Overview
Rfreplacement is an open-source printed circuit board by c0pperdragon, from the c0pperdragon/C64-Video-Enhancement repository on GitHub, published under the MIT licence. It is a 2-layer board of 61 × 64.1 mm with 98 parts on 140 nets, routed with 1,151 tracks and 101 vias.
It is built around the 10M02SCE144I7G, THS7316D and LM1117IMPX-3.3. Its parts include 40 resistors, 34 capacitors, 3 inductors, 1 IC and 1 connector. It belongs with the FPGA and CPLD boards of this library.

smallreplacement/README.mdSmall RF Replacement
I made a smaller variant of the RF replacement board that can be used in C128 machines as well as in the C64C. By not supporting the "long" C64 boards with their 12V VIC, this FPGA board could be made as small as the smaller variant of the RF modulator and this should now also fit where the original board was too large.

Questions
How big is the Rfreplacement PCB?
It measures 61 × 64.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rfreplacement use?
98 parts, built around the 10M02SCE144I7G, THS7316D and LM1117IMPX-3.3. 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 Rfreplacement KiCad files?
From the c0pperdragon/C64-Video-Enhancement repository on GitHub, at the commit this page was made from: the board is rfreplacement/rfreplacement.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rfreplacement 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).
