ADDRESS JumperThe MCP23017 I2C interface can have up to 8 unique bus addresses. The Centipede Shield uses X00 to X11, where X is the value of the ADDRESS jumper. This allows the Centipede Shield address space to be shifted by four places, either to prevent interference on the I2C bus with another device, or to allow two Centipede Shields to coexist.
So my question is, which pins represent the "Wire I2C interface on analog pins 4 and 5 " and can i just solder connections of two centipedes in a daisy chain arrangement?
