+
+A Game Boy flash cartridge designed to work without a plastic shell. 32KB, so perfect for small games like Tetris, or utilities like my [Better Button Test](https://github.com/orangeglo/better-button-test).
+
+Two parts...
+- [SST39SF010A](https://www.digikey.com/en/products/detail/microchip-technology/SST39SF010A-70-4C-WHE/2297827) flash chip
+- 0603 0.1uF ceramic cap
+
+Order as...
+- 2mm PCB (Up to 2.4mm may work as well, untested)
+- ENIG finish
+
+I recommend ordering from [JLC](jlcpcb.com), as they offer the 2mm option for a reasonable price at largish quantities.
