OpenESC-20x20 Rev 3
4-in-1 BLDC ESC, 20 x 20 mm mounting, 6-layer. Four independent AT32F421G8U7 controllers on AM32. 6S only, unchanged.
Input TVS removed
The 2x SMF24A-T13 are removed. Their 24 V standoff sits below the 25.2 V a full 6S pack reaches, so they conducted rather than protected. The board now has no input clamp; the DOY180N03T MOSFETs and the 165 A current-sense full-scale bound the envelope.
