Power board
About the Power board
Power board is an open source PCB design by kamilix2003, published on GitHub under the MIT license. It is a 2-layer board measuring 20.5 × 14.5 mm, with 18 components from 9 distinct parts.
Other key parts include the TPS60403DBV and AP2127K-3.3. By type, the board carries 8 capacitors, 3 diodes, 2 ICs, 2 connectors, 2 resistors and 1 fuse.
It belongs with the rf & radio and displays & leds designs in this gallery.
From the project
Interface for RF phase shifter as part of phased antenna array
STM32G0B01 based board for controlling daisy-chained digital phase shifter via SPI-like serial interface. User can interface with the board either by buttons and LEDs on the board or via virtual serial port over USB, communication over serial port is realized using simple TLV protocol. The board is providing bipolar supply for the phase shifters.
