Peak Peak Atlas ESR70 Gold – Low Resistance and Capacitance Meter
The Peak Atlas ESR70 Gold is an enhanced version of the previous Peak Atlas ESR70 Plus. It does everything that the ESR70 Plus did but better. It now measures capacitance up to 10x faster, and over a wider range, thanks to new test algorithms. The capacitance measurement is also much less influenced by parallel resistances or leakage current thanks to our new Triple-Slope measurement system. Using the supplied gold plated probes (removable), the Atlas ESR70 Gold can measure ESR down to a resolution of 0.01 ohms, up to 40 ohms. It can even measure ESR for capacitors that are in-circuit. Probes are removable, allowing 2 mm compatible probes to be fitted. Audible alerts are produced for various ESR levels allowing you to perform many tests in succession without having to look at the display. The ESR70 automatically takes capacitive reactance into account, so even low value capacitors (down to 0.3 uF) can have the ESR measured accurately. Features Uses a single AAA Alkaline cell (included). Alphanumeric LCD with backlight. Automatic analysis-start when you apply the probes. Automatic capacitor discharge using controlled discharge function. ESR (and low DC resistance) measurement (even in-circuit). Capacitive reactance automatically taken into account to ensure accurate ESR. Capacitance measurement (if testing out-of-circuit). Audible alerts for various ESR levels. Extended ESR measurement range up to 40 Ohms. Optional probe alternatives easily fitted. New Gold Features Improved LCD with better backlight. 10x faster capacitance measurement for large capacitors. Enhanced user options system. New triple-slope measurement system to vastly reduce the influence of parallel resistance and/or leakage current on capacitance measurements. Much wider capacitance measurement range now 0.3 uF to 90,000 uF (was 1uF to 22,000uF).

Adafruit Adafruit Feather 32u4 RFM69HCW Packet Radio (868 or 915 MHz) RadioFruit
Deze 900 MHz radio-versie kan worden gebruikt voor 868 MHz of 915 MHz transmissie/ontvangst – de exacte radiofrequentie wordt bepaald wanneer u de software laadt omdat deze dynamisch kan worden afgestemd.In het hart van de Feather 32u4 zit een ATmega32u4, geklokt op 8 MHz en op 3,3 V logica. Deze chip heeft 32 K flash en 2 K RAM, met ingebouwde USB, dus niet alleen heeft het een USB-naar-Serieel programma & debug mogelijkheid ingebouwd zonder noodzaak voor een FTDI-achtige chip, het kan ook fungeren als een muis, toetsenbord, USB MIDI-apparaat, enz.Om het gemakkelijk te gebruiken te maken voor draagbare projecten, hebben we een connector toegevoegd voor elke 3.7 V Lithium polymeer batterij en ingebouwd om de batterij op te laden. Je hebt geen batterij nodig, hij werkt prima rechtstreeks vanaf de micro USB connector. Maar als u wel een batterij hebt, kunt u die meenemen op reis en dan de USB aansluiten om op te laden. De Feather schakelt automatisch over op USB-voeding als die beschikbaar is. We hebben ook de batterij via een deler verbonden met een analoge pin, zodat je de batterijspanning kunt meten en monitoren om te detecteren wanneer je moet opladen.Functies Afmetingen 2.0' x 0.9' x 0.28' (51 x 23 x 8 mm) zonder headers erin gesoldeerd Licht als een (grote?) veertje - 5,5 gram ATmega32u4 @ 8 MHz met 3,3 V logica/voeding 3.3 V regulator met 500 mA piekstroomuitgang USB native ondersteuning, wordt geleverd met USB bootloader en seriële poort debugging U krijgt ook een heleboel pinnen - 20 GPIO-pinnen Hardware seriële, hardware I²C, hardware SPI-ondersteuning 7x PWM pinnen 10x analoge ingangen Ingebouwde 100 mA lipoly lader met oplaadstatus indicator LED Pin # 13 rode LED voor algemeen knipperen Voeding/contactpin 4 bevestigingsgaten Reset-knop De Feather 32u4 Radio gebruikt de extra ruimte die over is om een RFM69HCW 868/915 MHz radiomodule toe te voegen. Deze radio's zijn niet goed voor het overbrengen van audio of video, maar ze werken wel goed voor het verzenden van kleine datapakketjes als je meer bereik nodig hebt dan 2,4 GHz (BT, BLE, WiFi, ZigBee) SX1231 gebaseerde module met SPI interface Packet radio met kant-en-klare Arduino bibliotheken Gebruikt de licentievrije ISM-band ('Europese ISM' @ 868 MHz of 'Amerikaanse ISM' @ 915 MHz) +13 tot +20 dBm tot 100 mW uitgangsvermogen (uitgangsvermogen selecteerbaar in software) 50 mA (+13 dBm) tot 150 mA (+20 dBm) stroomverbruik voor transmissies Bereik van ca. 350 meter, afhankelijk van obstructies, frequentie, antenne en uitgangsvermogen Meerpuntsnetwerken met individuele knooppuntadressen maken Geëncrypteerde packet engine met AES-128 Eenvoudige draadantenne of spot voor uFL-connector Komt volledig geassembleerd en getest, met een USB bootloader waarmee je het snel kunt gebruiken met de Arduino IDE. Er worden ook koppen meegeleverd zodat je hem kan solderen en in een soldeerloos breadboard kan steken.

Adafruit Adafruit Feather RP2040
Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all thier native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).Technical Specifications Measures 2.0 x 0.9 x 0.28' (50.8 x 22.8 x 7 mm) without headers soldered in Light as a (large?) feather – 5 grams RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V logic and power 264 KB RAM 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM Tons of GPIO! 21 x GPIO pins with following capabilities: Four 12 bit ADCs (one more than Pico) Two I²C, Two SPI and two UART peripherals, one is labeled for the 'main' interface in standard Feather locations 16 x PWM outputs - for servos, LEDs, etc The 8 digital 'non-ADC/non-peripheral' GPIO are consecutive for maximum PIO compatibility Built in 200 mA+ lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking RGB NeoPixel for full color indication. On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I²C devices with no soldering! Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code) 3.3 V Power/enable pin Optional SWD debug port can be soldered in for debug access 4 mounting holes 24 MHz crystal for perfect timing. 3.3 V regulator with 500mA peak current output USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging RP2040 Chip Features Dual ARM Cortex-M0+ @ 133 MHz 264 kB on-chip SRAM in six independent banks Support for up to 16 MB of off-chip Flash memory via dedicated QSPI bus DMA controller Fully-connected AHB crossbar Interpolator and integer divider peripherals On-chip programmable LDO to generate core voltage 2 on-chip PLLs to generate USB and core clocks 30 GPIO pins, 4 of which can be used as analog inputs Peripherals 2 UARTs 2 SPI controllers 2 I²C controllers 16 PWM channels USB 1.1 controller and PHY, with host and device support 8 PIO state machines Comes fully assembled and tested, with the UF2 USB bootloader. Adafruit also tosses in some header, so you can solder it in and plug it into a solderless breadboard.
