As the first wireless product in the Seeed XIAO family, Seeed XIAO BLE has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM® Cortex™-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz. With the capability of wireless connection, it still remains the Seeed XIAO series classic form-factor of small and exquisite which can be used for wearable devices and Internet of Things projects. Furthermore, it only costs 5 μA in the deep sleep model and it supports battery charge management because of the BQ25101 chip. To better support IoT and TinyML AI projects, there is an advanced version “Seeed XIAO BLE Sense” that carries both 6-axis IMU and PDM microphones.

Compare to XIAO RP2040, XIAO BLE has a richer interface. The first thing to note is that the Near Field Communication(NFC) is functional on the board. Secondly, there is a tiny and elegant reset button on one side of the Type-C interface. On the other side, it is designed in a three-in-one LED along with power LED. There are 11 digital i/o that can be used as PWM pins and 6 analog i/o that can be used as ADC pins. It supports UART, IIC, and SPI all three common serial ports. Same as Seeed XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages.

    The SEEED xiao was a disappointing board. It started in the first bootup but after using once it stopped displaying as arduino/ circuitpython board. I tried st-link, jtags but no avail.
    I recommend anyone considering this to spend a bit more and invest in the more reliable adafruit ble boards available on robu
