2S-6S 2A x2 Dual-Channel Bidirectional Brushed ESC

A tiny two-channel brushed motor controller that drives two small DC motors forward and in reverse from one board. It suits 370 and 520-size geared motors in tracked vehicles, tanks and small RC cars, as long as each motor's rated current stays at or below 2 A.

Key features

• Two independent bidirectional channels, 2 A each with 4 A peak
• Wide 6–25 V input, covering 2S to 6S LiPo
• 5 V / 1.5 A BEC to power the receiver
• Signal-loss protection: after a dropout, return the throttle to centre to re-arm
• Over-current protection and a 130 °C over-temperature cut-out
• 25 × 16 mm board at 19 g, with an aluminium heat sink

Specifications

• Channels: 2, bidirectional
• Current: 2 A per channel, 4 A peak
• Input: 6–25 V (2–6S LiPo)
• BEC: 5 V, 1.5 A max (linear regulator)
• Board size: 25 × 16 mm
• Weight: 19 g

The BEC is a linear regulator, so it runs hot above 4S or when it feeds a high-current servo; in those setups power the servo from a separate UBEC. Do not pair it with 540-size or other high-current motors — repeated over-current burns the board even with protection on. It is built for ground vehicles and is no substitute for a brushless drone ESC.
