About the Relatively-Universal-ROM-Programmer PCB

Relatively-Universal-ROM-Programmer is an open source PCB design by AndersBNielsen, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 68.8 × 53.6 mm, with 141 components from 30 distinct parts.

Other key parts include the MIC2288, 74HC573 and C146583. By type, the board carries 65 resistors, 34 diodes, 12 transistors, 12 capacitors, 8 connectors and 5 ICs.

It belongs with the usb & debug tools and dev boards & breakouts designs in this gallery.

From the project

Hardware to program W27C512 EEPROM or any 24/28/32 pin ROM requiring from 5V to 27V programming voltage.

This is meant to be a cheap way to program W27C512 EEPROMs which require 14V erasure voltage and 12V programming voltage... Or basically any other 24/28/32 pin ROM requiring from 5V to 27V programming/erasure voltage.

You can either make your own, get a PCB from JLCPCB using the guide below or order a kit with SMD components presoldered from iMania.dk (sockets available if needed). Kits with SMD components presoldered are available from my store, iMania.dk
