this is motor driver address details
I2C Address Selection
The default I2C address is 0x12. ADR2 shorted to GND will set the address to 0x14, ADR1
shorted to GND will set the address to 0x16, ADR1 and ADR2 shorted to GND will set the
address to 0x18. If the PPM signal is shorted to GND on start-up the driver will set the
addresses as 0x22, 0x24, 0x26 and 0x28 instead of 0x12, 0x14, 0x16 and 0x18. This allows for
an additional 4 address
