Super nRF52840 is a replacement for the Xiao nRF52840, and they share the same pinout. Super52840 uses the Xiao bootloader, and compared to the Xiao nRF52840, it provides 7 additional I/O pins located on the back of the board (P0.31, P0.15, P0.19, P1.01, P1.03, P1.07, P1.05).
The Super nRF52840 features the powerful Nordic nRF52840 MCU, integrated with Bluetooth 5.0 connectivity, and comes in a compact and sleek form factor, making it ideal for wearable devices and IoT projects. The single-sided PCB design and onboard Bluetooth antenna greatly facilitate the rapid deployment of IoT projects.
Super52840 integrates a charging indicator LED and a tri-color LED. It offers 11 digital I/O pins that can be used as PWM pins, and 6 analog I/O pins that can serve as ADC inputs. It supports three common serial interfaces: UART, I2C, and SPI. The board also includes 2MB onboard memory, and can be programmed using Arduino, MicroPython, CircuitPython, or other programming languages.
