If you have just unboxed a small, blue or black heatshrink-wrapped device labeled "Brushless ESC V2.3," you are likely holding one of the most ubiquitous yet poorly documented pieces of RC electronics on the market. Whether you are building an FPV drone, a 1/10 scale RC rock crawler, a mini racing boat, or a 3D printed plane, the V2.3 Brushless ESC is a workhorse.
Plug this into your receiver’s Throttle channel (usually Channel 2 on airplane/helo radios, or Channel 1 on some pistol grips). Ensure the ground wire matches the negative pin on the receiver. brushless esc v2.3 manual

The V2.3 rarely comes with a programming card (though some generic Hobbywing or SkyRC cards work). Most users must use the Transmitter Stick Programming method. The Ultimate Brushless ESC V2
Brushless ESC v2.3 is a compact electronic speed controller for 3‑phase brushless DC motors (BLDC). It supports bidirectional motor control, programmable throttle response, regenerative braking, and multiple protection features (over‑current, over‑temperature, low‑voltage cutoff). Intended uses: RC cars, boats, small drones, robotics, and hobby projects. Ensure the ground wire matches the negative pin
