Board

Summary

This mod is writted for the PIC16F630 microcontroller. This mod is written with the SDCC. Maybe the SDCC is not the best for PIC, but it do the job very well.

How to compile and program

This MOD must be compiled with SDCC. To program the micro I suggest the Minipro/XGecu programmer. But i'm sure it can be programmed with the PICKit.

To compile use the "--use-non-free" parameter. Or use the MAKEFILE in the firmware directory.

License

The PCBs are under the CERN OHL license. The firmwares, under the GPL3.

This is an OPEN project. So, like any other project like this, the hope is that others can improve it an reshare with the community. Don't go out this basic guideline.

Questions

How big is the MD Mod PCB?

It measures 20.3 × 20.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MD Mod use?

19 parts. 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 MD Mod KiCad files?

From the screwbreaker/MDmod repository on GitHub, at the commit this page was made from: the board is PDK/MD_Mod.kicad_pcb and its schematic PDK/MD_Mod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MD Mod design in my own project?

Its repository states no licence, so its author keeps all rights: ask screwbreaker before reusing the design.
