De ESP8266 is een indrukwekkende, goedkope WiFi module die geschikt is om WiFi functionaliteit toe te voegen aan een bestaand microcontroller project via een UART seriële verbinding. De module kan zelfs worden geherprogrammeerd om te fungeren als een standalone WiFi connected device – voeg gewoon stroom toe! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Geïntegreerde TCP/IP-protocolstack Deze module is een zelfstandige SOC (System On a Chip) die niet noodzakelijkerwijs een microcontroller nodig heeft om inputs en outputs te manipuleren zoals u normaal gesproken zou doen met bijvoorbeeld een Arduino, omdat de ESP-01 fungeert als een kleine computer. Je kunt dus een microcontroller internettoegang geven zoals het Wi-Fi shield doet bij de Arduino, of je kunt de ESP8266 gewoon programmeren om niet alleen toegang te hebben tot een Wi-Fi netwerk, maar ook te fungeren als een microcontroller, wat de ESP8266 zeer veelzijdig maakt.
Deze Wi-Fi module is gebaseerd op de populaire ESP8266 chip. De module is FCC en CE gecertificeerd en voldoet aan RoHS. Volledig compatibel met de ESP-12E. 13 GPIO-pinnen, 1 analoge ingang, 4 MB flash-geheugen.
Pico Breakout Garden Base sits underneath your Pico and lets you connect up to six of our extensive selection of Pimoroni breakouts to it. Whether it's environmental sensors so you can keep track of the temperature and humidity in your office, a whole host of little screens for important notifications and readouts, and, of course, LEDs. Scroll down for a list of breakouts that are currently compatible with our C++/MicroPython libraries!As well as a labelled landing area for your Pico, there's also a full set of broken out Pico connections, in case you need to attach even more sensors, wires, and circuitry. We've thrown in some rubber feet to keep the base nice and stable and to stop it from scratching your desk, or there are M2.5 mounting holes at the corners so that you can bolt it onto a solid surface if you prefer.The six sturdy black slots are edge connectors that connect the breakouts to the pins on your Pico. There's two slots for SPI breakouts, and four slots for I²C breakouts. Because I²C is a bus, you can use multiple I²C devices at the same time, providing they don't have the same I²C address (we've made sure that all of our breakouts have different addresses, and we print them on the back of the breakouts so they're easy to find).As well as being a handy way to add functionality to your Pico, Breakout Garden is also very useful for prototyping projects without the need for complicated wiring, soldering, or breadboards, and you can grow or change up your setup at any time.Features
Six sturdy edge-connector slots for breakouts
4x I²C slots (5 pins)
2x SPI slot (7 pins)
Landing area with female headers for Raspberry Pi Pico
0.1” pitch, 5 or 7 pin connectors
Broken-out pins
Reverse polarity protection (built into breakouts)
99% assembled – just need to stick on the feet!

Thanks to its six sturdy slots, Breakout Garden enables the users to simply plug and play with various tiny breakout board.Just insert one or more boards into the slots in the Breakout Garden HAT and you’re ready to go. The mini breakouts feel secure enough in the edge-connector slots and are very unlikely to fall out.There are a number of useful pins along the top of Breakout Garden, which lets you connect other devices and integrate them into your project.You shouldn't be worried if you insert a board the wrong way thanks to provided reverse polarity protection. It doesn't matter which slot you use for each breakout either, because the I²C address of the breakout will be recognised by the software and it'll detect them correctly in case you move them around.Features
Six sturdy edge-connector slots for Pimoroni breakouts
0.1” pitch, 5 pin connectors
Broken-out pins (1 × 10 strip of male header included)
Standoffs (M2.5, 10 mm height) included to hold your Breakout Garden securely

It's suggested using the included standoffs to attache Breakout Garden to your Raspberry Pi.SoftwareBreakout Garden doesn't require any software of its own, but each breakout you use will need a Python library. On the Breakout Garden GitHub page you'll find an automatic installer, which will install the appropriate software for a given breakout. There are also some examples that show you what else you can do with Breakout Garden.
De MLX90640 SparkFun IR Array Breakout heeft een 32×24 array van thermopile sensoren die, in essentie, een lage resolutie warmtebeeld camera genereren. Met deze breakout kan je oppervlaktetemperaturen vanop een behoorlijke afstand waarnemen met een nauwkeurigheid van ±1.5 °C (in het beste geval). Dit bord communiceert via I²C met behulp van het door Sparkfun ontwikkelde Qwiic systeem, wat de bediening van de breakout vergemakkelijkt. Er zijn echter nog steeds 0,1'-spaced pinnen voor het geval u de voorkeur geeft aan het gebruik van een breadboard. Het SparkFun Qwiic connect systeem is een ecosysteem van I²C sensoren, actuatoren, shields en kabels die het prototypen sneller maken en u helpen fouten te voorkomen. Alle Qwiic-compatibele borden gebruiken een gemeenschappelijke 1 mm pitch, 4-pins JST-connector. Dit vermindert de benodigde PCB ruimte, en gepolariseerde aansluitingen helpen u alles correct aan te sluiten. Deze specifieke IR Array Breakout biedt een gezichtsveld van 110°×75° met een temperatuurmeetbereik van -40 °C ~ 300 °C. De MLX90640 IR Array heeft pull up weerstanden op de I²C bus; beide kunnen worden verwijderd door de sporen op de overeenkomstige jumpers aan de achterkant van de printplaat door te knippen. Let erop dat de MLX90640 complexe berekeningen vereist van het host platform, dus een gewone Arduino Uno (of gelijkwaardig) heeft niet genoeg RAM of flash om de complexe berekeningen uit te voeren die nodig zijn om de ruwe pixel data om te zetten in temperatuur data. U heeft een microcontroller nodig met 20.000 bytes of meer RAM.
