Witty Pi is een add-on bord dat realtime klok- en energiebeheer toevoegt aan uw Raspberry Pi. Het kan de ON/OFF-volgorde van uw Raspberry Pi bepalen, en het energieverbruik aanzienlijk verminderen. Witty Pi 4 is de vierde generatie van Witty Pi en het heeft deze hardware aan boord: In de fabriek gekalibreerde en temperatuurgecompenseerde realtime klok met ±2 ppm nauwkeurigheid. Eigen temperatuursensor met 0,125 °C resolutie. On-board DC/DC converter die tot 30 V DC accepteert. AVR 8-bit microcontroller (MCU) met 8 KB programmeerbare flash. Nauwkeurige real-time klok en aan/uit-schema De realtime klok (RTC) op Witty Pi 4 is in de fabriek gekalibreerd en de firmware van Witty Pi 4 maakt ook temperatuurcompensatie voor het kristal. Hierdoor is de RTC zeer nauwkeurig en is de werkelijke jaarlijkse fout beperkt tot ±2 ppm. Wanneer uw Raspberry Pi opstart, zal de tijd opgeslagen in de RTC de systeemtijd overschrijven. Hierdoor weet uw Raspberry Pi de juiste tijd, zelfs zonder toegang tot het internet. U kunt het opstarten en/of afsluiten van uw Raspberry Pi plannen, en er een tijdgestuurd apparaat van maken. U kunt zelfs een schema-script definiëren om een ingewikkelde aan/uit-sequentie voor uw Raspberry Pi te plannen. Het plannen van de aan/uit-volgorde voor Raspberry Pi is de populairste functie van Witty Pi, en het is erg handig voor systemen die gevoed worden door een batterij. Door Raspberry Pi alleen aan te zetten wanneer dat nodig is, kan de batterij veel langer meegaan als Witty Pi is geïnstalleerd. Temperatuur-gestuurd apparaat De temperatuursensor op Witty Pi 4 heeft een resolutie van 0,125 °C. De temperatuurgegevens worden gebruikt om het kristal te compenseren en de RTC nauwkeuriger te maken. U kunt ook de actie (opstarten of uitschakelen) specificeren wanneer de temperatuur boven of onder de vooraf ingestelde drempel komt. Dit betekent dat u van uw Raspberry Pi ook een temperatuurgestuurd apparaat kunt maken. DC/DC converter en e-latching power switch Witty Pi 4 wordt geleverd met een DC/DC converter aan boord, waarmee u uw apparaat kunt voeden met 6~30V voeding. U kunt uw apparaat ook van 5 V voorzien via de USB type C connector. Witty Pi 4 heeft ook een e-Latching aan/uit-schakelaar, die veel lijkt op de aan/uit-schakelaar op uw PC/Laptop computer. U kunt uw Raspberry Pi aan/uit zetten met een enkele tik op de knop. De software die op de achtergrond draait, voert het uitschakelcommando uit voordat de stroom wordt uitgeschakeld, dit voorkomt dat gegevens worden beschadigd door hard uitschakelen. Witty Pi 4 ondersteunt alle Raspberry Pi modellen die de 40-pins GPIO header hebben, inclusief A+, B+, 2B, Zero, Zero W, Zero 2 W, 3B, 3B+, 3A+ en 4B. U moet de 40-pins header van tevoren aan het Zero/Zero W/Zero 2 W model solderen, zodat ze een betrouwbare verbinding met Witty Pi kunnen maken. Een enkel I²C-apparaat Witty Pi 4 gebruikt MCU om een enkel I²C-apparaat met standaard adres 0x08 te emuleren, en mapt ook alle I²C-registers in realtime klok en temperatuursensor als virtuele I²C-registers in hetzelfde apparaat. U kunt alle I²C registers in de realtime klok en temperatuursensor benaderen via het enkele I²C apparaat dat door Witty Pi 4 wordt geëmuleerd. Het voordeel van dit nieuwe ontwerp is dat Witty Pi 4 andere I²C-apparaten (realtimeklok, temperatuursensor) verbergt en de proxy van hen wordt om met Raspberry Pi te praten. Omdat het door Witty Pi 4 gebruikte I²C-adres in elke waarde kan worden veranderd, kunt u altijd voorkomen dat het I²C-adres conflicteert. UWI ondersteuning Witty Pi 4 wordt volledig ondersteund door UWI (UUGear Web Interface), en u kunt toegang krijgen tot uw Witty Pi 4 op elk apparaat dat netwerk toegang heeft.

The Picon Zero is an add-on for the Raspberry Pi. It has the same size as a Raspberry Pi Zero, making it ideal to function as a pHat. Of course, it can be used on any other Raspberry Pi via a 40-pin GPIO connector.As well as two full H-Bridge motor drivers, the Picon Zero has several Input/Output pins giving you multiple configuration options. That allows you to easily add outputs or analog inputs to your Raspberry Pi without any complicated software or kernel-specific drivers. At the same time, it opens up 5 GPIO pins from the Raspberry Pi, and it provides the interface for an HC-SR04 ultrasonic distance sensor.The Picon Zero comes with all components, including the headers and screw terminals, fully soldered. Soldering isn't required. You can use it right out of the box.Features pHat format PCB: 65 mm x 30 mm Two full H-Bridge motor drivers. Drive up to 1.5 A continuously per channel, at 3 V - 11 V. Each motor output has both a 2-pin male header and a 2-pin screw terminal. The motors can be powered from the Picon Zero's 5 V or an external power source (3 V - 11 V). The Picon Zero's 5 V can be selected to be from the Raspberry Pi's 5 V line, or a USB connector on the Picon Zero. That means that you can effectively have 2 USB battery banks: one to power the servos and motors on the Picon Zero and the other to power the Pi. 4 Inputs that can accept up to 5 V. These inputs can be configured as follows: Digital inputs Analog inputs DS18B20 DHT11 6 Outputs that can drive 5 V and be configured as: Digital Output PWM Output Servo NeoPixel WS2812 All Inputs and Outputs use GVS 3-pin male headers. 4-pin female header that connects directly to an HC-SR04 ultrasonic distance sensor. 8-pin female header for Ground, 3.3 V, 5 V, and 5 GPIO signals allowing you to add their additional features. Hardware ConfigurationPicon Zero has two jumpers for setting the hardware configuration. Ensure that you have placed them in the correct position. JP1 – Board 5 V Selector. This jumper selects where to get the 5 V power from for the Picon Zero Outputs. The options are: Jumper at the top between RPI and 5 V. The 5 V power for the board is taken from the Raspberry Pi pins on the GPIO connector. Because of the low power output devices and the 5 V motors, all devices can be powered with a single 5 V power input. Jumper at the bottom between USB and 5 V. The 5 V power is taken from the microUSB connector on the Picon Zero. Useful for higher power output devices, since you can provide extra power through the micro-USB connector on the board JP2 – Motor Power Selector. This jumper selects where the motors get the power. The two options here are the following: Jumper at the top between MotorPower and Vin. The motors are driven via the 2-pin screw terminal. The voltage can be between 3 V and 11 V. Useful for motors that require a voltage different from 5 V, or that require more current than is available on either of the USB input connectors Jumper at the bottom between 5 V and MotorPower. The motors are driven from the board's 5 V. Raspberry Pi ConfigurationThe Picon Zero is an I²C device. Make sure your Raspberry Pi is set up correctly to use I²C and SMBus: sudo apt-get install python-smbus python3-smbus python-dev python3-dev sudo nano /boot/config.txt Add the following lines at the end of the file dtparam=i2c1=on dtparam=i2c_arm=on Press Ctrl-X and use the default prompts to save sudo reboot Plugin the Picon Zero onto the Pi and run i2cdetect -y 1If everything goes well, you will see the Picon Zero showing up as address 22 as shown below:

The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485.The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs.A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. CompatibilityThe card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.Power RequirementsThe Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. RelaysThe 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF.Stacking Multiple CardsUp to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.Features Eight relays with status LEDs and and N.O contacts Eight layer stackable Eight 12-bit A/D inputs, 250 Hz sample rate Four 13-bit DAC outputs (0-10 V dimmers) Four PWM 24 V/4 A open-drain outputs Eight optically isolated digital inputs Contact closure/Event counters up to 500 Hz Four Quadrature Encoder inputs 26 GPIOs from Raspberry Pi available 1-WIRE and RS485 communication ports Pluggable Connectors 26-16 AWG for all ports On-board hardware watchdog On-board resettable fuse Reverse power supply protection Brass stand-offs, screws and nuts included Hardware self-test with loop-back cable Open source hardware, schematics available 32-bit Processor running at 64 MHz Uses only I²C port (address 0x28..0x2f ), all GPIO pins available Specifications Power supply: Pluggable Connector, 5 V/3 A Power consumption: 50 mA (all relays off), 700 mA (all relays on) On board resettable fuse: 3 A Open Drain outputs: maximum 3 A, 24 V Relays 1,2,3,4,5,8: N-O contacts, 6 A/24 VAC or DC Relays 6,7: 3 A/24 VAC or DC Analog Inputs: Maximum input voltage: 3 V Input Impedance: 50 K?

Raspberry Pi 4 was welcomed by the Pi enthusiasts for the increased processing power. However, this came at a price. The RPi 4 can draw up to 3 Amps, which means it has to dissipate 15 W of power. Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available.The Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack.DIN-Rail MountingTogether with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications.Stack Level JumperTwo Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling.
