RGB LEDs (WS2812)
User programmable WS2812B RGB LED. Connected to GP18.
Programmable Buttons
Accessible from the user program. Connected to GP20 and GP21
Piezo Buzzer
Can be used to play tone or melody. Connected to GP22.
Buzzer Mute Switch
Used to mute the piezo buzzer.
GPIO Status LEDs
LED indicators for RP2040 GPIOs on Grove Ports.
Turn on when the GPIO state is high.
Motor Test Buttons
Press to test the functionality of the motor driver.
Motor will run at full speed.
● MxA : Forward*
● MxB : Backward*
Servo Ports
Connectors for 4 x RC servo motors.
Signal is connected to GP12, GP13, GP14 and GP15.
V+ voltage is equal to power source voltage.
Motor Status LEDs
Turn on when the motor is running.
● MxA : Forward*
● MxB : Backward*
DC Motor Terminals
Connect to the motor terminal.
Motor voltage at full speed is equal to power source voltage.
Motor direction is dependent on the polarity.
● M1A : GP8
● M2A : GP10
● M1B : GP9
● M2B : GP11
Table 1: MAKER-PI-RP2040 Board Functions
∗ Actual motor direction is dependent on the motor connection.
Swapping the connection (MxA & MxB) will reverse the direction.
