Features: 2oz coppered foil 4-layer Printed Circuit Board ensures high current flows. Double synchronous rectification bucked BEC, 5V continuous 3A, 12V continuous 2A (up to 3A) output. Battery adjustable solder pads are arranged in pair for easy soldering of wires. Multiple option for images transmission and camera voltage, signal collection. The BEC input terminal has TVS protections to prevent high-voltage spark from impacting the direct current chip during battery insertion and removal. Same size as Naze32, CC3D flight control, weighing only 6g. Specifications: Material: Printed Circuit Board Size: Approx. 36x36mm/1.42x1.42inch Package Includes: 1x Power Distribution Board note: Pay attention to input polarities, do not reverse or short-circuit input! To obtain a stable BEC 12V output, the battery needs 4 to 6S. When using a 3S battery, BEC 12V cannot function properly. You can choose "VCC" to power the camera and images transmission. Do not touch the carbon fiber board behind the distribution board as it is prone to short circuits. Please use nylon column to isolate the installation.
