This project uses multiple I2C breakouts. As a result, their addresses need to be adjusted by either soldering or cutting the address jumpers.
There are five ANO rotary encoder breakouts. These will be on addresses 0x49-0x4D.
- 0x49 - default address, leave jumpers as-is
- 0x4A - cut jumper A0
- 0x4B - cut jumper A1
- 0x4C - cut jumpers A0 and A1
- 0x4D - cut jumper A2
There are five alphanumeric display breakouts. These will be on addresses 0x70-0x74.
- 0x70 - default address, leave jumpers as-is
- 0x71 - solder jumper A0
- 0x72 - solder jumper A1
- 0x73 - solder jumpers A0 and A1
- 0x74 - solder jumper A2
