About the Multicartridge smd-32u4-front dipswitch PCB

Multicartridge smd-32u4-front dipswitch is an open source AVR/Arduino PCB design by ifilot, published on GitHub. It is a 2-layer board measuring 80 × 100 mm, with 72 components from 32 distinct parts.

Its main chip is the ATmega32U4-A, from the AVR/Arduino family. Other key parts include the 74HC00, SST39SF020, 74HC157, 74HC573 and 74HC123. By type, the board carries 27 capacitors, 23 resistors, 12 ICs, 3 connectors, 2 switches and 1 transistor.

From the project

Collection of homebrew P2000T cartridges

A SLOT1 cartridge designed to enable selection from 32 memory banks, assuming the use of a 512KB ROM chip. It features a dedicated bracket PCB for holding the DIP switch, which can be connected to the main PCB using either six wires or a custom flex cable. Additionally, this cartridge includes a soft reset switch, equipped with a debouncing circuit using a 74HC123 multivibrator. This cartridge uses THT components.
