Designed for ultra-low power consumption at just 5μA in deep sleep, it supports battery charging via the BQ25101 chip. With a rich interface including UART, IIC, SPI, and 2MB flash memory, it’s programmable via Arduino, CircuitPython, and MicroPython, making it ideal for wearable devices, IoT, and TinyML applications. ## Description 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 a 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. Review: Bought to use as SteamVR Dongle - 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. Review: Mauvais produit... - 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 !!! ## Features - 📌【Powerful CPU】As the first wireless product in the Seeed XIAO family, Seeed Studio XIAO nRF52840 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. - 📌【Wireless Capabilities】XIAO nRF52840 has Bluetooth 5.0 NFC module with an onboard antenna.
