15. Classroom:bit(CR00003)#

15.1. Introduction#

Classroom:bit is a breakout board for micro:bit, it has extended the IO ports on micro:bit in the form of GVS, through which they are availble to connect with all octopus sensors in 3v, such as the LED light, the light sensor, the servos and etc., the buzzer and noise sensor are also loaded on it. The classroom:bit and micro:bit v1.5 has all functions that you can find in micro:bit v2.0. ../_images/classroombit-1.png

15.2. Characteristics#

  • Extend all the I0 ports in the form of GVS.

  • With the onboard buzzer and noise sensor, the classroom:bit and micro:bit v1.5 has all functions that you can find in micro:bit v2.0.

  • Lead out the IIC connections seperately, it’s able to connect with OLED, BME280 and the other IIC products.

  • Support Lego connections.

Powering through the USB cable is fine(or through a micro:bit), if connecting to servos or other similar devices that need high currency, it’s recommended to power through the USB.

GVS#
