RPi Pin Connects to
4 (5V) Relay VCC (Headlight)
6 (GND) Relay GND (Headlight)
7 (GPIO4) L298N D2 (Left Motors Forward)
9 (GND) L298N GND (0V)
11 (GPIO17) L298N D1 (Left Motors Reverse)
13 (GPIO27) L298N D4 (Right Motors Forward)
15 (GPIO22) L298N D3 (Right Motors Reverse)
16 (GPIO23) Relay SIGNAL (Headlight)
12 (GPIO18/PWM0) Pan Servo SIG
18 (GPIO13/PWM1) Tilt Servo SIG

 
 

L298N Motor Driver

The L298N motor driver module is screwed to the undercarriage of the bot. Each side’s pair of motors is connected in parallel to one output of the L298N.

L298N Pin Connects to
12V SLA Battery +12V
0V (GND) SLA Battery GND
M1+, M1- Left Hand Side Motors
M2+, M2- Right Hand Side Motors
5V 5V output for camera servos
