## Description

The Adafruit LED Glasses Driver is a slim, Bluetooth-enabled controller board built around the Nordic nRF52840 chipset. Originally designed to drive the Adafruit LED Glasses RGB LED matrix, it also works brilliantly as a compact standalone development board with built-in sensors and STEMMA QT connectivity. Unlike standard Feather boards, this driver trades GPIO breakout pins for a slim profile with onboard sensors — a LIS3DH triple-axis accelerometer for motion and orientation sensing, and a PDM digital microphone for audio sensing. If you need GPIO access, consider the ItsyBitsy nRF52840, Feather nRF52840 Express, or Feather nRF52840 Sense instead. Key Features nRF52840 Processor – ARM Cortex M4F at 64 MHz with hardware floating point, 1 MB flash, and 256 KB SRAM Bluetooth Low Energy – 2.4 GHz radio with FCC/IC/TELEC certified module, up to +8 dBm output power Native USB – No separate USB serial chip needed; supports CDC serial, HID (keyboard/mouse), mass storage, MIDI, and more via TinyUSB Built-in Sensors – LIS3DH triple-axis accelerometer and PDM digital microphone 2 MB External QSPI Flash – For CircuitPython file storage STEMMA QT Connector – Plug-and-play I2C for adding sensors and peripherals Battery Support – JST PH 2-pin battery port with optional LiPo charging (enable via solder jumper) On/Off Switch – Proper power cutoff to microcontroller and external sensors UF2 Bootloader – Drag-and-drop firmware updates; no special tools required Dual Platform Support – Works with both Arduino IDE and CircuitPython Ideal For Driving the Adafruit LED Glasses front panel Compact wearable electronics and cosplay projects Bluetooth-enabled sensor projects with motion and audio Portable I2C sensor hubs via STEMMA QT Package Contents 1× Adafruit LED Glasses Driver (nRF52840 Sensor Board) Note: This board has no GPIO breakout pins. LiPo charging is disabled by default — short the solder jumper on the back to enable it, and only use 4.2 V/3.7 V rechargeable batteries.
