Botlab Dynamics BotDrive 8-Bit 4-in-1 ESC 50A

The Botlab Dynamics BotDrive 8-Bit is a 4-in-1 ESC manufactured in India, built around the EFM8BB21F16G microcontroller and FD6288Q MOSFET driver for smooth, precise motor control on 5-inch freestyle and racing builds.

Key features

• EFM8BB21F16G 8-bit MCU with FD6288Q MOSFET driver for clean throttle response and stable commutation.
• 50A continuous per motor (60A burst), running on 2–6S LiPo input.
• Pre-flashed with BLHeli_S firmware (JH50 target), supporting DShot300/600 and PWM protocols for compatibility with common flight controllers.
• Compact 30.5x30.5mm mounting on a 40x41mm board keeps the stack light.
• Designed and manufactured in India, giving domestic drone builders a locally made alternative.
