Display module
About the Display module
Display module is an open source PCB design by i-melnichenko, published on GitHub under the MIT license. It is a 2-layer board measuring 35.6 × 41.3 mm, with 8 components from 7 distinct parts.
Other key parts include the 74LS00 and 74LS373. By type, the board carries 2 ICs, 2 capacitors, 1 connector and 1 resistor.
It belongs with the displays & leds designs in this gallery.
From the project
An open-source modular computer built around the Intel 8088 CPU.
An open-source modular computer built around the Intel 8088 CPU.
This project explores the design of a modular 8088-based computer using through-hole DIP components and a custom expansion architecture.
The project is developed incrementally, starting with a minimal working system and gradually adding new hardware and software capabilities.
The default firmware is a minimal ROM BIOS. It builds a 32 KiB EEPROM image, initializes an HD44780-compatible 20×4 LCD on Exp1, copies the bundled program to SRAM, and transfers control to it.
