MT22A-OPTO-SF32 BLHeli 32bit Firmware Brushless ESCs for Multi-copter/UAV Drone

MT22A-OPTO-SF32 BLHeli 32bit Brushless ESCs for Multi-copter/UAV Drone/Hexacopter/Quadcopter BLHeli 32bit controllers are specially used for Multi-copter/Multi-rotors. 32bit mcu are used, enable the controllers have faster and more smooth throttle response than standard controllers. Main features: Excellent startup performance, great throttle linear and quick throttle response, excellent low-speed performance. Separate voltage regulator IC for MCU (Micro Controller Unit), high capability of anti-interference. Low-voltage protection, block-rotation protection and signal lose protection, etc. All these functions can effectively prolong ESC service life. Programmable by Trx or by a Maytech programming card (optional). Program-Card has a simple and visual surface to conveniently change parameters at any time anywhere. Safe start-up. The motor won’t be started no matter which position the throttle stick is on when battery connected. Motor rotating direction can be changed by exchanging two
