README
README.mdPower Framework Expansion Card
Non-isolated 5V output with a 500 mA current limit.
Pinout
To connect to this board, one has to use a 2-pin JST XH connector. The following table represents the pinout, pin 1 being on the left as looking into the expansion card.
| # | Ref | Description |
|---|---|---|
| 1 | GND | Ground connection |
| 2 | 5V | Positive voltage |
LEDs
Left LED signals if input is powered. It is expected to be on at all times.
Right LED signals if output is powered and there are no faults. It will turn off
if there is an over-current state (typically at around 525 mA).
Commands
Each char is a separate command. If it is recognized, output will be tilde
character (~), original command, and CR``LF.
| Char | Description |
|---|---|
0 | No smoothing for voltage and current |
1 | Voltage and current read are smoothed over 2 readings |
2 | Voltage and current read are smoothed over 4 readings |
3 | Voltage and current read are smoothed over 8 readings |
4 | Voltage and current read are smoothed over 16 readings |
5 | Voltage and current read are smoothed over 32 readings |
6 | Voltage and current read are smoothed over 64 readings |
7 | Voltage and current read are smoothed over 128 readings |
8 | Voltage and current read are smoothed over 256 readings |
9 | Voltage and current read are smoothed over 512 readings |
d | Disable output |
D | Disable output and allow saving for startup |
e | Enable output |
E | Enable output and allow saving for startup |
S | Saves current settings |
Any command state that can be saved permanently (e.g. E) needs to be followed
by S command in order to be saved.

Questions
How big is the PowerFEC PCB?
It measures 24 × 27.9 mm and has 2 copper layers, 0.8 mm thick.
What parts does the PowerFEC use?
28 parts, built around the PIC16F1455-I/P, ZXCT1009FTA, AP22652W6 and B2B-XH-A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PowerFEC KiCad files?
From the medo64/PowerFEC repository on GitHub, at the commit this page was made from: the board is hardware/PowerFEC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerFEC design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
