GPIO #
The Orange Pi zero has 2 Rows of GPIOs a 2x13 row and a 1x13 row.
The numbers on the board are not the numbers that you will be able to use in your program.
There is a formula that will help you to get the GPIO number when you have the pin number:
(Position of letter in alphabet - 1) * 32 + Pin number
For example, port PB12 would map to GPIO 44:
(2 - 1) * 32 + 12 = 44
