Product overview
The HAKRC 12S 50A is a 4-in-1 electronic speed controller with stacked hardware that separates the control board from the power board. Its AT32F421G8U7 controller operates at up to 120MHz, alongside an FD6288Q three-in-one IC driver. The power board uses eight layers and 3 oz copper foil, with two 80V MOS devices connected in parallel. Resin-plugged PCB holes, a double-pad layout and metallized edging form part of the construction, with the edging intended to help retain the pads during use.
Integration requirements include a 56*52 mm board footprint, 34.5g net product weight and a 6S-12S LiPo input. The controller supports PWM, Oneshot125, Oneshot42, Multishot and Dshot150/300/600, and uses HAKRC-AT4G-Rev.32.9-muiti firmware. Included circuitry comprises an ammeter for real-time bus-current detection, industrial-grade DC-DC circuitry and Japanese Murata filtering capacitors. The 50A continuous-current specification carries a specific qualification: operation for about 50s in a sealed constant-temperature box. Peak current is 60A, and the specified current ratio is 135.
