One of the best microcontrollers imo, works so well and has through charging a 3.7v lipo battery pads on the bottom. This is my 2nd favorite microcontroller seeed makes. My all time fav is Xiao-mg24. It has everything this controller has but also has a microphone and accelerometer built on!

I was dubious. But I use these little guys everywhere. Nice, low power consumption, very versatile. Easy to set up with the Arduino IDE (or similar environments), well-documented, and have had zero trouble with any of the I/O on the XIAO, despite my inadvertent, accidental attempts to put their tolerances to the test.These boards are one of my most frequently used project boards, and they find their way into the majority of my prototyping builds.

These were something of a chore to flash, but once you figure it out, they function great. they are really small and battery life is outstanding. i would certainly rebuy these.

Lots of code support online for getting this up and running. Easily had it serving a website on my local network for remote control via ngrok, plus powered some pretty hefty motors with only USB power and no issues. Impressive for the price and size.

Very easy to use compared to some of the other esp32 boards I've picked up from amazon. The serial IO usbc port connects seamlessly to my pc and I can very easily use platformIO or the arduino IDE to flash it and monitor serial output. Will definitely buy more for future IoT projects

These are game changers with home assistant. With a little work and know how, you can automate anything.

Very quickly becoming my favorite MCU, it can definitely be more powerful than needed, but after spending days googling and debugging cheaper and less powerful chips in the hopes of keeping dev costs down, i'd rather have a sturdy v6 under the hood than deal with an undocumented, poor designed 4 cylinder.Has less pins than your esp32 dev or wroom modules but if you need multiple serials and don't want to play the software serial bit bashing game, this thumb sized chip will do it without issue, i've yet to get that with the wroom even though it boasts supposedly 3 uarts..Cheaper dual core, 4mb 160mhz can be had for between 4 and 7 bucks a piece, but with at least double the footprint, without onboard lithium charge host, 5v regulator that can handle solar input and so far really good support. you can even go cheaper with a single core for about 2 bucks each.. but the HOURS and HOURS googling issues or error messages because the seller has the entire support site in chinese, outdated pin out diagrams, narrow community support will each that savings up.seeed studio has a nice chat tool that quickly googlefu's for you results for error messages that might appear and quite a few peripheral providers (oleds, sensors) have xiao esp32 specific libraries available.definitely would grab several if they go on sale

It's a great little board. Now even easier to program using ChatGPT.

Works great for my application. Comes with stick on antenna.Works well with Arduino IDE using the USB connection.

Ich habe mir dieses Board als Ersatz für meinen altes ESP32 Board geholt, dass nicht mehr richtig performt hatte. Ich habe es relativ simpelt gehalten und als Bluetooth Proxy via ESPHome auf meinem Home Assistant konfiguriert, um den Gardena Bewässerungscomputer anzubinden. Das Ganze lief mit dem alten Board über 2 Jahre lang relativ stabil. Das Problem fing damals allerdinbgs schon mit der extrem begrenzten Reichweite des Bluetooth Empfang an, was dazu führte, dass ich den Proxy sehr nah am Bewässerungscomputer platzieren musste. Der Empfang reichte nicht wenn ich das Board in der IP65 Box verstaut hatte (1,5m Entfernung zum Computer) und musste aus der Box rausgeführt und nah platziert werden. Vermutlich ist das Board deshalb dann auch letzten Endes ausgestiegen. Auch das Pairing mit dem Gardena war immer ein Krampf.Das nun erworbene ESP32-C3 Board von Seeed Studio überzeugt was Reichweite und Handling angeht, auf ganzer Linie. Dem Board liegt eine kleine Antenne bei, die ich angebracht habe. Wenn ich mir die Bluetooth Karte im Home Assistant anschaue, dann sieht es aus als ob der die gesamte Nachbarschaft scannt (Scanmodus ist "aktiv").Wer nach einem Günstigen, kleinen und unkompliziertem Bluetooth Proxy für sein Smart Home Projekt sucht ist mit diesem Board hier bestens bedient. Klare Kaufempfehlung!

This is a very good microcontroller board for both beginners and professionals. It has built in wifi and built in battery management system. I love it ❤️.
