Allow easy access to all the I/O pin on the Pine A64 header
On board 4pcs of LED with current limiting resistor all direct connect to I/O pin for status indicator
On board 4pcs of Tact switch
On board XH5 2.54mm pitch connector for UART0 allow easy connection to USB/UART adapter for console access
POT: Multi I2C Bus (PMI2C01)
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
