ESC Programming Card

Configuring a brushless ESC's behavior - when it cuts power on a low battery, how it handles braking, its timing advance - normally means connecting it to a computer and running configuration software, which is overkill when a quick field adjustment is all that's needed. This card does the same job standalone: plug the ESC in, step through settings with the four-button interface (ITEM, VALUE, OK, RESET), and the indicator light confirms each change, no laptop or software required.

Compatibility across 45A, 60A, 80A, and 120A ESC ratings covers the common current range used in everything from small quads to larger multirotor builds, and its compact 80 x 55 x 12mm size makes it genuinely pocketable for field use rather than something left on a workbench. Because it works directly with the ESC's own programming protocol, it functions independently of whatever flight controller or software ecosystem a particular build uses.

Common uses are field-adjusting ESC low-voltage cutoff and braking settings without a laptop, initial ESC setup and testing before installing into a build, and quick parameter changes between flights when a build's behavior needs tuning on the spot.
