Product Introduction

The Super nRF52840 is equipped with the powerful Nordic nRF52840 MCU, featuring Bluetooth 5.0 connectivity. It also boasts a compact and exquisite design, making it suitable for wearable devices and IoT projects. The single-sided surface mount design and onboard Bluetooth antenna greatly facilitate the rapid deployment of IoT projects.

Super52840 integrates a charging indicator light and a three-color LED. There are 11 digital I/Os available as PWM pins, and 6 analog I/Os can be used as ADC pins. It supports three common serial interfaces: UART, I2C, and SPI. The board contains a built-in 2MB memory, and can be programmed using Arduino, Micropython, CircuitPython, or other programming languages.

Super52840 is an alternative product of Xiao nRF52840. They have the same pin arrangement. Super52840 uses Xiao's Bootloader. Compared with Xiao nRF52840, Super52840 has 7 additional IO pins, located on the back of the board (P0.31, P0.15), P0.19, P1.01, P1.03, P1.07, and P1.05).
