Als erstes drahtloses Produkt in der Seeed XIAO-Familie hat Seeed XIAO BLE eine leistungsstarke Nordic nRF52840 MCU ausgestattet, die in einem Bluetooth 5.0-Modul entwickelt wurde, das um 32-Bit-ARM Cortex-M4-CPU mit Floating-Point Unit (FPU) mit 64 MHz arbeitet. Mit der Fähigkeit der drahtlosen Verbindung bleibt es immer noch der klassische Formfaktor der Seeed XIAO Serie von klein und exquisit, der für tragbare Geräte und Internet of Things Projekte verwendet werden kann. Des Weiteren kostet es nur 5μA im Tiefschlafmodell und es unterstützt das Batterielademanagement aufgrund des BQ25101-Chips. Um IoT- und TinyML-KI-Projekte besser zu unterstützen, gibt es eine erweiterte Version "Seeed XIAO BLE Sense", die sowohl 6-Achsen-IMU- als auch PDM-Mikrofone trägt.
Im Vergleich zu XIAO RP2040 hat XIAO BLE eine reichhaltigere Schnittstelle. Das erste, was zu beachten ist, ist, dass die Near Field Communication (NFC) auf dem Board funktioniert. Zweitens gibt es eine winzige und elegante Reset-Taste auf einer Seite der Typ-C-Schnittstelle. Auf der anderen Seite ist es in einer Drei-in-Eins-LED zusammen mit einer Power-LED konzipiert. Es gibt 11 digitale i/o, die als PWM-Pins verwendet werden können, und 6 analoge i/o, die als ADC-Pins verwendet werden können. Es unterstützt UART, IIC und SPI alle drei gängigen seriellen Ports. Genau wie Seeed XIAO RP2040 verfügt er über einen integrierten 2-MB-Flash, was bedeutet, dass er auch von Arduino, MicroPython, CircuitPython oder anderen Programmsprachen programmiert werden kann.

For the size and price this little sbc is a beast. Granted it is not fast and does not have a ton of space, but there are loads of features packed into this tiny package. The XIAO series boards are like the Tardis of SBCs, bigger on the capabilities than the tiny footprint should allow.

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

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.

These modules just don't like USB3 ports.Could not get any programs to upload, got a "not in DFU mode" error. And it suggested grounding some mysterious unknown "DFU" pin. I have similar Adafruit nRF52840 boards and they work just fine.After some time of trying this and that, I tried a USB2.0 port on the Windows 10 machine I am running the Arduino IDE on. After that programs would upload in the "DFU" mode. I almost returned this module, but seems to work now.One more thing. The XIAO-nRF52840 has a teeny weeny, tiny, tiny, microscopic reset button. You need to double click this to enter the "DFU" mode.When the "DFU" mode is entered, a "D" drive will appear in "This PC" and a COM port will become available.When this module was plugged into a USB3 port the "D" drive would appear, but it showed no files on the drive and accessing it would produce an error. Plugged into a USB2.0 port the "D" drive contains three files and the DFU program upload through the COM port succeed. After an upload the "D" drive and the COM port disappear and require a double click of the teeny, teeny, tiny reset button to upload another program.Also, I, for the heck of it, uploaded a program the the Seeed module using the board set to the Adafruit Feather nRF52840 module. That may of had some additional curative effect on the XIOA module.

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.
