Description Seeed XIAO BLE nRF52840 Sense
This is the powerful Seeed XIAO BLE nRF52840 Sense of Seeed Studio. It's a small microcontroller board which is equipped with a Nordic nRF52840 MCU. It includes a Bluetooth 5.0 module for wireless connection. The XIAO BLE nRF52840 Sense contains two built-in sensors. One digital microphone and one 6-axis IMU (Inertial Measurement Unit).
Like the standard XIAO BLE, contains Seeed XIAO BLE Sense a rich interface. The first thing to notice is that the Near Field Communication (NFC) is functional on the board. Second, there is a small and elegant reset button on one side of the Type-C interface. On the other hand, it is designed in a three-in-one LED along with a power LED. There are 11 digital I/Os that can be used as PWM pins. There are 6 analog I/Os that can be used as ADC pins. It supports UART, IIC and SPI all three common serial ports.
The module has 2MB flash. You can program it with Arduino, MicroPython, CircuitPython or other programming languages.
