ARK 4IN1 ESC
NDAA compliant, made in the USA, 4 in 1 electronic speed controller running open source ARK32 firmware.
Before first use, configure KV, Pole Count, and Ramp Rate for each motor channel in the ARK32 Configurator. The KV/pole defaults will not match your motor. Factory ramp is 2 %/ms — lower it for large props. See ARK32 Configuration.
This ESC runs ARK32. Use ARK32 on this board. See Why ARK32.

Capacitance:
The ARK 4IN1 ESC has 450µF of bulk capacitance built in, which is sufficient for most 3S–6S installations with short battery leads.
For 8S and above, add an external bulk capacitor across the battery input to keep switching and inrush transients below the 65V absolute maximum. Long battery leads increase inductance and make transients worse at any voltage.
