클루 보드 -nRF52840 익스플레스 BLE, 센서, LCD
(Adafruit CLUE - nRF52840 Express with Bluetooth LE)
개요
- 본 제품은 micro:bit 보드와 유사한 폼팩터를 가진 CLUE 보드입니다.
- nRF52840 SoC 및 많은 센서와 1.3인치 디스플레이를 탑재하고, micro:bit 과 같은 edge connector를 장착하고 있는 제품으로 BLE를 지원합니다.
- IMU 센서, APDS9960 근접, 조도, 컬러, 제스쳐 센서, PDM 마이크로폰 사운드 센서, SHT 습도센서, BMP280 온도 및 대기압 센서를 장착하고 있습니다.
- 2개의 사용자 버튼, 리셋버튼, RGB LED, 버저, 스피커, Qwiic/STEMMA QT 커넥터 또한 지원합니다.
- 아두이노 IDE나 CircuitPython을 이용하여 프로그래밍이 가능합니다.

Revision history:
- As of March 13, 2020 we've made some changes from the previous ALPHA version to move the screen slightly so its a little more centered, and some components moved around to account for the screen connector move. The design is otherwise identical to ALPHA (hardware, shape, pinout, etc)
Product Dimensions: 51.7mm x 42.2mm x 12.3mm / 2.0" x 1.7" x 0.5"
Product Weight: 13.0g / 0.5oz

While the CLUE looks a bit like a 'bit it has totally redesigned-from-scratch technology:
- Nordic nRF52840 Bluetooth LE processor - 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor
- 1.3″ 240×240 Color IPS TFT display for high resolution text and graphics
- Power it from any 3-6V battery source (internal regulator and protection diodes)
- Two A / B user buttons and one reset button
- Tons of sensors!
- RGB NeoPixel indicator LED
- 2 MB internal flash storage for datalogging, images, fonts or CircuitPython code
- Buzzer/speaker for playing tones and beeps
- Two bright white LEDs in front for illumination / color sensing.
- Qwiic / STEMMA QT connector for adding more sensors, motor controllers, or displays over I2C. You can plug in GROVE I2C sensors by using an adapter cable.
- Programmable with Arduino IDE or CircuitPython
Please note that at this time there is no MakeCode or Scratch support for the nRF52840 chipset (of course, we'd love to see MakeCode but there is no ETA when it may be added). While the CLUE is the same outline and we did our best to make the edge-connector pins match up, most cases for the 'bit wont fit the CLUE, and code may not be immediately compatible without adjustment, especially since only Arduino and CircuitPython are supported at this time.
