Pin data pending — do not wire from this page.Every pin assignment below is a placeholder (TBD). Nothing here has been verified against the Delta hardware. Wiring from placeholder data will damage the controller, the motor, or both.Until this page is filled in, take pin assignments from the board silkscreen or the schematic.
This page documents the physical connectors on the Delta GaN ESC (REV A) and what each pin carries.

​
Power and phase

High current and high voltage. The Delta accepts up to 93 V continuous and delivers up to 70 A continuous with forced airflow. Never make or break these connections under load, and use an anti-spark connector on the battery side.

​
Battery input

​
Phase output

Phase order determines direction of rotation. Prefer flipping the direction toggle in Motor Settings over swapping phase wires — see motor tuning.

​
Signal connectors

​
Control input connector

Carries the throttle and control signals configured in input configuration.
The 5 V rail’s current budget is TBD. Do not power a receiver, companion computer, or servo from it until that figure is confirmed.

​
UART

​
CAN

Termination: TBD — whether the Delta includes an on-board 120 Ω terminating resistor, and whether it is switchable, is not yet documented.

​
USB

USB-C, data only. The Delta is not powered over USB and will not enumerate until DC power is applied to the main input terminals. Use a USB A → USB C cable. See the quickstart.

​
Mechanical

Filling this in: replace each TBD with the verified value, then remove the warning at the top of the page. Every figure should be traceable to the schematic or a measured board — not inferred.
