This board is designed to be a thin, bluetooth-enabled driver board for our Adafruit LED Glasses RGB LED matrix. That said, it's a perfectly good stand-alone development board for the Nordic nRF52840 chipset, with a very slim design, optional LiPo battery support, a few sensors, and a Stemma QT port for adding other devices or sensors with I2C plug-and-play. The driver looks a little like a Feather but it does not have any breakout pins to keep it very compact. If you need access to GPIO pins, we recommend an nRF52840 ItsyBitsy, nRF52840 Feather or Feather Sense.

Features:

ARM Cortex M4F (with HW floating point acceleration) running at 64MHz
1MB flash and 256KB SRAM
Bluetooth Low Energy compatible 2.4GHz radio (Details available in the nRF52840 product specification)
FCC / IC / TELEC certified module with up to +8dBm output power
2MB external QSPI flash for CircuitPython file storage
Built in LIS3DH accelerometer and PDM microphone
Red LED for general purpose blinking, plus a tiny NeoPixel for colorful feedback
STEMMA QT connector for plug-and-play I2C support.
JST PH 2-pin battery port with optional LiPoly charger

Package Include

1 x Adafruit LED Glasses Driver - nRF52840 Sensor Board

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
