JGA25-370B DC Geared Motor with Encoder (12 V) is a compact 12-volt brushed DC gear motor with an integrated quadrature encoder and is commonly supplied with a wheel hub for smart car and robot chassis kits. It is designed for applications where both high torque and precise speed or position feedback are needed.
Operating voltage: 12 V DC
Motor type: Brushed DC motor
Gearbox: Metal reduction gearbox (25 mm diameter)
Encoder: Hall-effect quadrature encoder (A/B outputs)
Output shaft: 4 mm D-shaped shaft
Wheel hub: Often included for direct wheel mounting in robot chassis kits.
Speed:123RPM
Most models have 6 wires:
Motor power
Red: Motor +
White (or Black): Motor –
Encoder
VCC (3.3–5 V)
GND
Channel A
Channel B
The motor wires connect to a motor driver (such as an L298N, TB6612FNG, or DRV8833), while the encoder wires connect to digital input pins on a microcontroller like an Arduino or ESP32.
Common applications
Smart robot cars
Differential-drive robots
Line-following robots
Autonomous mobile robots (AMRs)
AGVs (Automated Guided Vehicles)
Conveyor systems
DIY robotics projects
Advantages
High torque from the metal gearbox
Accurate speed and position feedback
Durable construction
Compatible with Arduino, ESP32, Raspberry Pi, and STM32
