POT: Multi I2C Bus (PMI2C01)

 PMI2C01 Board Layout.JPG
 Feature
 Sit on top of Pine A64 board
 All the header receptor will have extended length pin to allow other POT board to insert on top of it
 Allow easy access to all the I/O pin on the Pine A64 header
 2 channel of I2C bus is wire out for easy access
 I2C bus repeater IC (PCA9517A) are included in each I2C bus to allow connection of more devices on each bus
 Support 3.3V and 5V I2C bus for each channel separately
 On Board separated 3.3V supply regulator for 3.3V I2C Bus 
 Each I2C bus pin are protected with ESD protector devices
 Each channel consist of 4 pcs of XH 4 pin 2.54mm pitch connector and 2 pcs of XH 5 pin 2.54mm pitch connector
 For the XH 4 pin connector, will consist of GND,SCL,SDA,5V pin
 For the XH 5 pin connector, will consist of GND,nINT,SCL,SDA,5V pin
 5V supplier is direct connect from Pine A64 adapter's supply thus prevent over loading Pine A64 board
 The nINT pin will allow peripheral with interrupt pin link back to the Pine A64 I/O pin
