Highly Integrated & Compact
XRotor Micro 40A 4in1 ESC features 32bit MCU and 3rd-generation BLHeli-32 firmware,
handles 6S up to 40A per channel. The built-in voltameter module which allows FC to
monitor the battery volt & amp in real time. With this 20x20 ESC makes your electronic
stack smaller and be able to shave some grams.
High Quality Hardware
High performance 32bit ARM MCU can run at 48MHz. 3IN 1 IC drive. Imported mosfet and
ceramic capacitor. 3 ounces of copper, 8 layers. Greatly reduce heat. More efficient.
BLHeli-32 Firmware Ready
The ESC flashed with the 3rd-generation BLHeli-32 firmware has great
performance & rich functions and supports adjusting parameters or upgrading
firmware via different ways (i.e. via throttle signal wire with using other
development board or a FC flashed with the Cleanfight/Betaflight firmware).
Unique soft mount
The soft mounts prevent vibrations from being transferred to the FC.
Soft wiring and welder pads for the best possible connection.
DShot1200 Ready
Besides the regular PWM mode, Oneshot125/Oneshot42/Multishot
modes, DShot150/300/600 modes, the latest DShot1200 mode is
also supported. In DShot1200 mode, the ESC has great
anti-interference performance and rapid response.
Hardware Generated PWM & Damped Light Mode
The ESC firmware uses hardware generated motor pwm for
smooth throttle response and silent operation. Damped light
does regenerative breaking, causing very fast motor retardation,
and it inherently also does active freewheeling.
