Specifications
- 8 three-pin ports (signal, power, ground)
- Ports 1–8 carry Mainboard signals IO1–IO8
- Port power 5 V or 3.3 V, set by a jumper
- Connect servos, soil moisture sensors, motion sensors, buttons, LEDs and other analog sensors
- You can stack another module on top of it
- Uses: plant watering, robotic arms, motion alarms
Pins
Each port uses only its own signal. If you leave a port empty, its signal stays free for the other modules in the tower.
| Pin | Function |
|---|---|
| IO1 – IO8 | Signal of port 1–8 (S) |
| 5V / 3.3V | Port power (+), selected by a jumper |
| GND | Port ground (−) |
Example code
Try the example Servo dial right in your browser in Eduingo AI Lab. The servo is plugged into port 1 of the Connect and turns its arm as you turn the potentiometer. Try reversing the range to 180 to 0. Which way does the servo turn now?
