Power board
About the Power board
Power board is an open source PCB design by nikola825, published on GitHub under the MIT license. It is a 4-layer board measuring 44 × 47.5 mm, with 96 components from 9 distinct parts.
Other key parts include the AP7381-50Y-13 and AP7381-33SA-7. By type, the board carries 40 capacitors, 24 transistors, 24 resistors, 6 ICs, 1 connector and 1 diode.
It belongs with the robotics & motion designs in this gallery.
From the project
Hobby home-made fpv quadcopter
This folder contains PCBs for a 1x and a 4x ESC. Mostly inspired by the AM32 reference hardware
AM32REF_F051 target can be flashed using standard AM32 flashing process.
The boards are supposed to be soldered together using the castellated edges on the logic board and pads on the power board.
It has no high power requirements. Can be fabricated as a cheaper 1 Oz/ft^2 thickness PCB
