Product overview
The Maytech MT32A-4N1-SF32 is a four-in-one brushless electronic speed controller intended for multicopters and quadcopters. Its physical integration requirements comprise a 36 × 36 mm footprint, a listed 30.5 mm mounting-hole dimension and a net weight of 13 g. The controller uses Maytech 32-bit BLHeli firmware and a 32-bit MCU. A separate voltage-regulator IC supplies the MCU, with interference resistance identified as a feature. The electrical specification lists 32 A continuous current, 42 A burst current, a 3 A / 12 V SBEC and support for 2–4-cell LiPo batteries.
This is an ESC component for integration into a flight system. Its control features include throttle linearity, quick throttle response, low-speed operation and coordinated response across the ESCs. Low-voltage, blocked-rotation and signal-loss protection are included, while safe startup inhibits motor operation when the battery is connected regardless of throttle-stick position. Parameters can be programmed by Trx or an optional Maytech programming card; the card is an accessory option. Motor direction can be changed either through the programming card or by exchanging two of the three wires from the ESC.
