The DYS XM20A ESC's are a BLHeli 20 amp capable electronic speed controller. These are designed to operate high KV motors. They are designed for quick multi-rotor throttle response with a refresh rate of the throttle signal of up to 500Hz. This is compatible with all modern flight controllers including boards running F3 chips. Features OneShot125 with 3000Hz refresh rate. Also programmable via USB and supports reversing of brushless motors and 3D modes. Motor direction is reversed by switching two wires when connecting the motor to the ESC.
Note: the only difference between the V1 and V2 models are that the V2's come with motor wires pre-soldered. V1's do not.
The circuitry and features are exactly the same other than this small detail.
