// This file contains the pin mappings for the Seeed XIAO BLE nRF52840 [Sense] boards.
|
|
//
|
|
// Seeed XIAO BLE is an ultra-small size, ultra-low power Bluetooth development board based on the Nordic nRF52840.
|
|
// It features an onboard Bluetooth antenna, onboard battery charging chip, and 21*17.5mm thumb size, which makes it ideal for IoT projects.
|
|
//
|
|
// Seeed XIAO BLE nRF52840 Sense is a tiny Bluetooth LE development board designed for IoT and AI applications.
|
|
// It features an onboard antenna, 6 Dof IMU, microphone, all of which make it an ideal board to run AI using TinyML and TensorFlow Lite.
|
|
//
|
|
// SoftDevice (s140v7) is pre-flashed on this board already.
