Quick Start
This guide introduces the FoBE Breakout GP8403 and how to use it.
Hardware diagram
The following figure illustrates the FoBE Breakout GP8403 hardware diagram.
Mechanical dimensions
FoBE Breakout GP8403 is a single-sided 25.4mm x 50.81mm (1" x 2") 1.6mm thick PCB with two SH1.0 4-pin connectors and a set of 6-pin 2.54mm header holes.
Output is provided by 4 x 3.81mm screw terminal blocks.
Fixing by 4(or more, up to 8) x 1.6mm Screw holes.
Interfaces
The board provides two 4-pin SH1.0 connectors, all providing the same IIC connections for MCU control.
| Interface | Description |
|---|---|
| GND | Ground |
| 3V3 | Power supply |
| SDA | I2C bus data line |
| SCL | I2C bus clock line |
And a set of 6-pin 2.54mm header holes, providing the same IIC connections for MCU control, plus an interrupt pin.
| Interface | Description |
|---|---|
| NC | Not Connected |
