Catalyst Dual Brushless ESC with Integrated Radio

Description

The Catalyst is an extremely compact dual brushless ESC with an integrated radio receiver, designed specifically for small combat robots.

It combines two brushless motor controllers with an AFHDS 2A 2.4 GHz receiver, eliminating the need for a separate receiver and saving valuable space and weight inside your robot. The ESC runs AM32 firmware and comes preconfigured, while still allowing advanced users to change the settings.

The board supports 2–6S LiPo batteries and has two additional PWM outputs that can be used for weapon ESCs or servos. Built-in mixing and an AUX switch for control inversion make it particularly convenient for combat robot drive systems.

The compact 19 × 29 mm footprint and 4 g weight make it a good choice when every gram and millimeter matters.
