## Description

30A bidirectional speed controller for brushed motors, ideal for RC cars and boats, robots or DIY projects, offers forward, reverse, brake modes for precise control and fast response. Operates at 4.8–8.4V with 2S LiPo or 4–7 NiCd cells, supports 30A forward 20A reverse and 40A peak, compatible with 130 180 260 280 380 motors.
30A bidirectional ESC (Electronic Speed Controller) for RC applications using brushed motors. The controller allows the motor to operate in forward, reverse and brake modes, providing precise control and fast response to commands.
It can be used in RC cars, boats, robots or other DIY projects that require bidirectional speed control.
Compatible with 130, 180, 260, 280 and 380 type motors, this ESC supports constant currents of 30A forward and 20A reverse, with peaks of up to 40A for short periods. It is compact, lightweight and efficient, providing an ideal solution for controlling DC motors in 2S LiPo or 4–7 cell NiCd systems.

Pin position | Name | Function | Description
1 | + (VCC) | Positive power input | Connect to the positive terminal of the battery
2 | – (GND) | Negative power input | Connect to the negative terminal of the battery
8 | M+ | Output to the engine | Brushed motor positive terminal
9 | M | Output to the engine | Negative terminal brushed motor
Signal connector | RC signal channel | PWM signal input | Connect to RC receiver (throttle channel)
Use:
Connect the wires from the M+ and M– outputs to the brushed motor terminals.
Connect the signal wire (usually 3 pins: signal, VCC, GND) to the RC receiver.
Connect the ESC to the appropriate battery (LiPo 2S or NiCd 4–7S).
Turn on the system and calibrate the acceleration signal according to the radio control instructions.
The brake function is automatically activated when the control suddenly switches from forward to neutral. The brake can be activated or deactivated from the dedicated switch.
