The Flatbox Rev 5 Passthrough aims to add USB passthrough to the Flatbox Rev 5 allowing easy access to a board which can use USB passthrough.
While BOM and CPL files are provided, it is recommended to order and assemble these yourself.
All of the boards so far have been ordered though JLCPCB. Due to minimum order numbers you would get five of these at a time. It is not recommended to have these assembed by JLC due to cost. If you are looking to have them assembled you should check out another project that has an embedded RP2040.
Please note that you will need to source and solder your own Waveshare RP2040-Zero board (or similar), passthrough port, tactile switches and hotswap sockets.

You will need the following parts to assemble the Flatbox Rev 5 USB passthrough: 6 x 6x6 tactile switches (height will depend on the case and button cap style you are intending to use, I went with 6x6x7 switches) 6 x tactile switch caps (these will also depend on how you want the finished product to look, I went with the newer rubber style ones) - 1 x Waveshare RP2040 Zero, clone or similar (I went with the RP2040 SuperMini for this) - LINK 1 x Mid-mount USB passthrough port - LINK 12 x Kailh Choc v1 hot-swap sockets - LINK 12 x Kailh Choc v1 or v2 switches
Please also note that only print files for the choc v1 caps are included. If you want to use Choc v2 switches you will need to source your own print files for the caps.
Optionally you can also get some of the new Choc v1 caps that are popping up on AliExpress. Please note that the ones linked HERE are an odd shape and you will need to use THIS larger hole top plate print.
