Description: AdafruitClue - nRF52840 Bluetooth LE - micro:bit compatible - Adafruit 4500.
The Adafruitdevelopmentboard, which supports Bluetooth communication and includes a number ofcommon sensors. It has a color TFT display and PDM MEMS microphone. It is equipped with a 3-axis accelerometer, gyroscope and magnetometer, it has a proximity, light, color and gesture sensor and humidity, temperature and pressure sensors. Powered from any source from 3 V to 6 V.Adafruit Clue ismicro:bitcompatible and can be programmed in Arduino IDE or CircuitPython environment.
The module is equipped with a13"colour IPSTFTdisplay with a resolution of240 x 240 px. Thanks to it both text and graphics are presented in high resolution. Additionally, there are two A / B buttons, one RESET button and NeoPixel RGB LED indicator. In order to ensure maximum comfort of use, the manufacturer has addeda buzzer,playing a sound signal and twoLEDs, which detect the light level and color.
The Adafruitdevelopment boardallows the user to usean impressive number of sensors.It consists of:
Accelerometer, gyroscope and magnetometer
- Proximity sensor, light, colour and gesture sensor
- humidity sensor
- temperature and pressure sensor
Adafruit development plate module.
