micro:bit용 다기능 확장 보드 micro:IO-BOX
(micro: IO-BOX Expansion Board
with On-board Li-ion Battery Power)
개요
- 본 제품은 micro:bit용 다기능 확장 보드 micro:IO-BOX입니다.
- 보드상에 리포 배터리를 장착할 수 있게 디자인되어 있으며, 2채널 모터 드라이버, 9개의 I/O 포트, 2개의 I2C 포트, 1개의 시리얼 포트, 버저, RGB LED, 리포배터리 충전회로 등을 탑재하고 있습니다.
- 보호 커버를 가지고 있어 좀더 안전하게 사용할 수 있습니다.
- CR123A 3.6V 1000mA 리튬 배터리와 사용이 가능합니다.
- 안정적인 전원공급을 위하여 좋은 품질의 부스트-벅 전원 관리 솔루션을 채택하였습니다.

- As we know, a motor's instantaneous current can reach up to 1A at its starting instant, which is a big challenge for power supply. So we specially carried out a strict test on our product: we make two TT motors keep rotating forward and reversely continuously, and even in such a condition, the board and motor can still work about 1.5 hours until running out of the battery. In normal operation, the battery can work for over 6 hours.
