•
4 digital IO connectors
E-brick Connector - Analog In/PWM Type
Pin ID Pin Name Remark
Pin#1 A1
Connect to a micro:bit pin with analog input/PWM function
Pin#2 A2
Same to A1, but most sensor module may not use the A2 pin
E-brick Connector - Digital IO Type
Pin ID Pin Name Remark
Pin#1 D1
Connect to a micro:bit pin with digital io function
Pin#2 D2
Same to D1, but most sensor module may not use the D2 pin
E-brick Connector - IIC Type
IIC (Inter-Integrated Circuit)
發音為
I-squared-C
是由飛利浦半導體（現在的恩智
浦半導體）發明的多主機
(master)
，多從機
(slave)
，單端，串行計算機總線。
它通
常用於在短距離，板內通信中將低速外設連接到微控制器。
有一些基於

IIC (Inter-Integrated Circuit)
, pronounced I-squared-C, is a multi-master, multi-
slave, single-ended, serial computer bus invented by Philips Semiconductor (now
NXP Semiconductors). It is typically used for attaching lower-speed peripheral to
microcontrollers in short-distance, intra-board communication.
