Interface Introduction

The Serial Expansion Module leads out all the I2C address lines, and can set the addresses of A0 and A1 through the jumper cap. In addition, there are 6 interrupt pins, which can stack up to 16 Serial Expansion Modules. The demo codes we provide is to set the address to 0x48, setting the interrupt pin to P5 (BCM), and setting the jumper caps as follows:

* Hardware Connection : Header

* I2C_Address: A0 -> 3V3 IRQ_PIN: IRQ -> P5

* A1 -> 3V3
