The i-MOD USB/I2C connector is a standard connector defined by Seco to allow customers to easily add functions to a baseboard.
Keith & Koep offers different extension boards ranging from a simple breakout board or an additional USB-type A connector to current-, voltage-, TOF-, NFC- sensors or IO-expander boards.
Customers may design their own peripherals which can be connected through a 10pol FFC cable.
This is the pinning of the connector on the baseboard.
Extension boards use the opposite numbering scheme.
Pin | Signal | Function |
|---|---|---|
1 | +5V | Power |
2 | USB_DM | USB D- signal |
3 | USB_DP | USB D+ signal |
4 | GND | Power |
5 | +3V3 | Power |
6 | I2C_CLK | I2C Clock signal |
7 | I2C_DATA | I2C Data signal |
