This is small form factor board, the layout and components are the same as the larger pcb you are able to use any compatible raspberry pi with this board. (3A+/B+/Zero2). The design of this board is for the pi zero2. If you have any questions please ask before purchase.
This is a newly made RAD Expansion Unit C64 cartridge. It does not work on its own you need to provide your own Raspberry Pi.
This is a good video about what the RAD is : https://www.youtube.com/watch?v=ObHsK_K6BXs&t=4s

The RAD Expansion Unit is a cartridge/expansion for the C64 and C128 using a Raspberry Pi 3A+, 3B+ or Zero 2 to implement the actual functionality. Currently it emulates a RAM Expansion Unit up to 16mb (compatible to CBM 1700/1750/1764 REU, CLD Super 1750 Clone, CMD 1750/1750XL) and a GeoRAM/NeoRAM memory expansion up to 4mb. It also features a menu to browse, manage and launch REU- and GeoRAM-images, NUVIEs, and PRGs. The RAD is designed to not only emulate existing extensions, other things that have already been tested (but not yet included here) are, for example, MOS 6510/8500 emulation (incl. turbo mode) or using the RAD as a (co-)processor (in fact the menu runs on the ARM CPU only).
