About the DRAM-Tester x1x4-lcd PCB

DRAM-Tester x1x4-lcd is an open source AVR/Arduino PCB design by goriponsoft, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100 × 100 mm, with 42 components from 23 distinct parts.

Its main chip is the Arduino Nano, from the AVR/Arduino family. Other key parts include the TC7660SCPA, MT3608 DCDC Module and I2C OLED Screen 0.91inch 128x32dot. By type, the board carries 18 resistors, 8 capacitors, 7 switches, 4 ICs, 2 LEDs and 1 connector.

It belongs with the displays & leds designs in this gallery.

From the project

DRAM tester that supports 4116/8265/4164/41256/4532/4416/4464/44256/4400 and is equipped with an LCD.

This is a stand-alone DRAM tester compatible with 4116/4164/41256/4532/4416/4464/44256 and equipped with an LCD. Although it is not a direct fork, it is created based on zeus074/dramtester and cloudree/DRAM_Tester. Thanks to the two original authors. Both of the two references are under the GPL3.0 license, so this DRAM tester will also be released under the GPL3.0 license.

DRAM-Tester x1x4-lcd: common questions

What microcontroller does the DRAM-Tester x1x4-lcd use?

The DRAM-Tester x1x4-lcd is built around the Arduino Nano, from the AVR/Arduino family.

How big is the DRAM-Tester x1x4-lcd PCB?

The DRAM-Tester x1x4-lcd measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DRAM-Tester x1x4-lcd?

42 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the DRAM-Tester x1x4-lcd design files?

From the goriponsoft/DRAM-Tester-x1x4-lcd repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the DRAM-Tester x1x4-lcd design in my own project?

Yes, under the terms of its GPL-3.0 license, which goriponsoft chose for the repository.

Can I test firmware for the DRAM-Tester x1x4-lcd without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
