XIAO nRF52840 - Supports Arduino/CircuitPython - Bluetooth5.0 NFC, with Onboard Antenna, Microcontroller with Rich Interface for Tiny Machine Learning Works with Amazon Sidewalk.

Bought a pair of these to use as SteamVR dongles to connect my Valve Index controllers to. Super easy to set up, just had to hold the button while the device was plugged into my PC, dragged and dropped the firmware onto the device, and was set to go. Much cheaper than any other aftermarket SteamVR dongle, works great.

I got one of these to replace a different nrf52 board. I was able to get a Bluetooth keyboard working and I love it! It uses the same SoC as the adafruit feather series and I was able to get most of their libraries working! I have ordered multiple as their small form factor makes them perfect for what I’m making. Small complaint that the arduino BSP includes the boot loader, but I can’t seem to figure out how to burn the factory boot loader back after I replaced it. It hasn’t affected any of my projects but I have wanted to revert back to the original boot loader a few times.

I bought a few of these for smaller projects. I have made several adruino projects with no issues but haven't been able to make these work. I'm pretty sure its my fault. I would consider myself at an intermediate skill level with Arduino but these seem to need a bit more skill. I also have trouble with the cheap knock off Arduino minis. It's most likely a settings issue. I dropped my star rating because of the skill needed to make it work even though its listed as if it can act a direct Arduino Uno replacement. Will be awesome once I get them to work right.

Good pricing on this, came with pins and all

These work great out of the box and have fantastic online support. Stable and going strong for me after a month of deployment.

The pads for the battery were damaged on arrival, the board has examples for Arduino but half of them don't compile...

fast shipping. Nice small processor board for prototyping.

I coded it in as recall micropython as well as arduino code. I used the BLE to talk to a phone app. Worked great. Didn't come with the pinout card/sticker but whatever.

Les ressources Seeed XIAO sont complexes à mettre en oeuvre, voir impossibles. J'utilise la carte en utilisant celles de son concurrent Adafruit en gravant la séquence d'initialisation de ce dernier. Mauvais produit !!!

Der Seed Studio XIAO BLE Nordic nRF52840 werkelt bereits erfolgreich in meinem neuen solarbetriebenen Meshcore- Repeater und saugt auch die Akkus nicht leer, wie ein seither verwendeter Heltec V4. Insgesamt eine lohnende Anschaffung!

コンパクトで、リポ1セル繋げばそれでおしまい。充電回路も入ってるし、arudinoで書けるから、まさに最高のおもちゃ。いや、おもちゃなんてことはでは言い表せないくらいの有能なパーツ。

他の方も言及していますが、出品者によって品質が異なるようです。 最初の出品者から購入した商品は、2つとも一部の入力を受け付けませんでした。 次の出品者から購入した商品は、2つとも動作に問題ありませんでしたが、USB-Cの端子の接続が認識されない時があります。向きを変えたり少し待って差し直せば認識します。また、Bluetoothに相性問題があるかもしれません。iPhoneとはすんなり接続できますが、WindowsPCとの接続が安定せず使い物になりませんでした。マイコン同士の通信も問題ないためWindowsPC側の問題な気がしますが、まあ安定しませんでした。 秋月電子など信頼のおける店舗で購入した方がいいかもしれませんね。

Ich verwende diesen Mikrocontroller mit CircuitPython. Ich wollte eine Emulation einer Bluetooth-Tastatur mit zeitlich automatisch wiederkehrenden Eingaben haben. Das klappt einwandfrei.
