This slim and versatile Bluetooth-enabled driver board is crafted for the Adafruit LED Glasses RGB LED matrix, doubling as a robust stand-alone development board for the Nordic nRF52840 chipset. Its compact design incorporates optional LiPo battery support, integrated sensors, and a STEMA QT port for seamless I2C device connections.Each board features a built-in LIS3DH triple-axis accelerometer for motion detection and a PDM digital microphone for audio analysis. The native USB support, Cortex M4 processor with 1 MB of FLASH, and 256KB of SRAM ensure high performance. The integrated TinyUSB support enriches USB capabilities, transforming the board into a USB CDC descriptor capable of acting as a keyboard, mouse, MIDI device, or storage drive.Additional features include a Cortex M4F processor with HW floating point acceleration running at 64MHz, FCC/IC/TELEC certified Bluetooth® LE radio, and 2MB external QSPI flash for CircuitPython file storage. With a JST PH 2-pin battery port, resetting capabilities, and mounting provisions, this board ensures optimal usability and performance. Pre-loaded with UF2 bootloader, it supports easy firmware updates with drag-and-drop functionality. https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2025-11-03 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2025-12-04 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2025-12-14 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2025-12-20 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2025-12-25 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-01-02 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-01-13 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-01-24 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-01-26 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-01-29 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-02-01 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-02-04 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-02-12 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-02-20 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-04 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-06 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-13 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-15 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-20 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-25 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-03-27 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-04-01 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-04-08 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-04-13 https://elecena.pl/product/29479098/adafruit-led-glasses-driver-nrf52840-sensor-board 2026-04-15
