Xiao BLE nRF52840 from Seeedstudio is the next product in the Seeed Xiao series. It is the equivalent of the Seeed Xiao BLE nRF52840 Sense board - the only difference is the lack of an IMU sensor and a PDM microphone. Xiao BLE nRF52840 has a small size of 21 x 17.5 mm and numerous communication interfaces, such as: 1x UART, 1x I2C, 1x SPI, 1x NFC, 1x SWD, 11x GPIO, 6x ADC, 1x LEDN 3in1, 1x user LED. Programming and powering the board takes place via the USB type C interface - it also charges the battery. The board is equipped with 2 MB of Flash memory, it can be programmed in Arduino, MicroPython, CircuitPython and other programming languages.
