Inside and outside the mini ESC distribution board 3oz copper foil 4-layer high PCB, all materials, high temperature resistance, good heat dissipation, to the passage of current, the actual measurement of each ESC distributes 50A current without problems. built-in 2-way DC-DC low Ripple step-down BEC, 5V continuous 3A, 12V BEC continuous 2A (maximum 3A, the measured 2.5A continuous and no problem) output video and camera voltage multiple (VCC, 12V, 5V), video signal hub size is 30.5* 30.5, compatible with mainstream flight controllers such as NAZE32, CC3D, and F3. Battery ESC pads are arranged in pairs for easy wire bonding Colour: Material:alloy usage notice: Pay attention to the input polarity, do not reverse the input, short-circuit to obtain a stable BEC 12V output, the battery needs 4~6S. When using a 3S battery, the BEC 12V cannot be regulated normally, and there may be an inductive sound. The output is 1~2V lower than the actual voltage of the 3S. You can "VCC" to power the camera and video transmission. Do not touch the carbon fiber board behind the distribution board, it is easy to short circuit. Please use nylon posts or double-sided tape to isolate and install. Weight: 6.2g Size:36 x 36mm Fixing hole distance: 30.5mm PCB thickness: 1.2MM Package Contents: 1 x distribution board Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
