my DRAMTester for 4164 and 41256 DRAM
DRAMduino
The DRAMTester shield is a Arduino UNO shield , to test DRAM 4164 and 41256 . It check the DRAM with diffrent read/write operations
Its based on the work on https://forum.defence-force.org/viewtopic.php?t=1699
This repository contains all eagle files, gerber file, BOM, schematics
Depending on where the parts and pcbs are purchased, the price for the complete shield is around 6€ (2023), without Arduino UNO and power supply I built this project, because the PCB on PCBWay has to small holes for all ZIF Sockets
