Back
You can change I²C address by cutting A0, A1, A2 at the back of board and soldering pull-up resistor on surface.The address at the time of shipment is 7 bit, and will be written 1001 000.
| A2 | A1 | A0 | Back(Right)Aligned 8bit signage | Front(Left)Aligned 8bit signage |
|---|---|---|---|---|
| 0 | 0 | 0 | 0x48 | 0x90 |
| 0 | 0 | 1 | 0x49 | 0x92 |
| 0 | 1 | 0 | 0x4A | 0x94 |
| 0 | 1 | 1 | 0x4B | 0x96 |
| 1 | 0 | 0 | 0x4C | 0x98 |
| 1 | 0 | 1 | 0x4D | 0x9A |
| 1 | 1 | 0 | 0x4E | 0x9C |
| 1 | 1 | 1 | 0x4F | 0x9E |
Front
When you have cut the short jumper at the back to change I²C address, you will need to solder chip resistor (1608 type, 10 KΩ) to R4, R5, R6.
Corresponds to:
A0 → R4
A1 → R5
A2 → R6
