A Wii RTC-RVL ("MX chip") relocation flex
This flexible PCB aims to simplify the relocation of the Wii MX chip, to make creating portables that utilise it as easy as possible.
Due to the overlapping of the via used for the U10, I decided to also relocate it onto here. I also added a solder pad if U10 emulation (like what's featured on the RVL-PMS line) is used, or if U10 is located elsewhere.
Additional pads were added for soft shutdown and the EXI bus, primarily for the RVL-DD.
This flex primarily reuses the original components found on the Wii motherboard, with the reference designators for the passive components matching the corresponding components from the Wii.
- R60 = 1kΩ, 0402 (1005 metric)
- D31 = 0603 (1608 metric) package, unknown specs
- C101, C102 = 5pF, 0402 (1005 metric)
- C98 = 100nF, 0402 (1005 metric)
To reduce space, the crystal has been swapped for a smaller one. Any crystal with a frequency of 32.768 kHz and a load capacitance of 4pF in a 2mm x 1.2mm package should work fine.
Some suitable replacements:

Questions
How big is the MXBreakout2 PCB?
It measures 47.2 × 28.3 mm and has 2 copper layers, 0.1 mm thick.
What parts does the MXBreakout2 use?
29 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 MXBreakout2 KiCad files?
From the VoxelTek/mxHound repository on GitHub, at the commit this page was made from: the board is old/MXBreakout2.kicad_pcb and its schematic MXBreakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MXBreakout2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask VoxelTek before reusing the design.
