SmartElex 30D Smart Motor Driver - 30A Dual Channel High-Power Driver for Combat Robots

For robots that demand raw power, the SmartElex 30D Smart Motor Driver delivers 30A continuous and 85A peak per channel - enough to run two large brushed motors in the most demanding competition robots. With four input modes (RC, Analog, PWM, Serial Packetized) and 16 kHz MOSFET switching for silent operation, it's the most capable Indian-made motor driver at this price point.

Specifications

• Channels: 2 (dual motor)
• Continuous current: 30A per channel
• Peak current: 85A (for 2 seconds) per channel
• Motor voltage: 7V-28V
• Logic: 3.3V / 5V compatible
• Input modes: RC, Analog, PWM, Serial Packetized
• Switching frequency: 16 kHz
• Protection: Overcurrent + thermal shutdown
• Mode selector: 4-position DPDT onboard switch
• Test buttons: onboard push buttons for manual motor testing

Why it beats generic high-current drivers

Most 30A boards use relays or linear H-bridges that heat up and burn out at peak loads. The SmartElex 30D uses low-Rdson MOSFETs at 16 kHz - no heat, no noise. The onboard microcontroller handles current limiting, thermal shutdown, and mode switching automatically.

Real-world projects

1. Heavyweight Combat Robot

Drive two 24V wheelchair motors from a LiPo pack via RC receiver for arena combat at national championships.

2. Agricultural Rover

Control large DC drive motors for a field navigation robot using PWM from Raspberry Pi 4.

3. Electric Go-Kart

Dual rear wheel drive with Analog throttle control from a Hall-effect pedal sensor at motor voltages up to 28V.

How it compares

RobotShop's equivalent dual 30A driver costs Rs.8,000+. The SmartElex 30D at Rs.4,128.30 is manufactured in India with a supplier warranty and is available with COD - unique at this power level.

FAQ

Q: What battery voltage is recommended?
A: 4S-6S LiPo (14.8V-22.2V) is ideal. The board accepts 7V-28V.

Q: Can I switch between RC and PWM modes without rewiring?
A: Yes - use the onboard 4-position DPDT switch to change modes without any wiring changes.

Q: What is the warranty on this product?
A: 6-month supplier warranty (this is a high-power product). Contact The Engineer Store Bengaluru team for claims.

Q: Does it support regenerative braking?
A: No. The 30D provides active braking via motor shorting, not regenerative braking.

Q: What motors are compatible?
A: Any brushed DC motor from 7V to 28V. Suitable for wheelchair motors, drill motors, and large hobby motors.
