Product overview
The DYS XMS30A mini version ESC is a motor-control component for multirotor racing installations using high-KV brushless motors. Its compact board measures 32 mm long by 15 mm wide and weighs 9.26 g, giving integrators concrete dimensions for allocating installation space. Integrated solder pads support direct wiring, while a built-in capacitor forms part of the controller’s electrical configuration. The specified power input is 3-6s LiPo, and the controller has no BEC, a material constraint when planning power for onboard electronics.
The controller combines a Silabs F396 processor, BLHeli bootloader and firmware, and a MOS 7440 driver. Its throttle connection uses twisted-pair cable to reduce signal crosstalk, and its PCB design addresses impact resistance. Throttle signal refresh reaches up to 500 Hz, with 3000 Hz specified for Oneshot125; Multishot is also enabled. USB programming provides configuration access, including two-way and 3D modes. Named integration matches include DYS MR and SE racing motors and the Naze32 Rev6 and SP Racing F3 flight controllers.
