About the EEPROM Programer PCB

EEPROM Programer is an open source RP2040/RP2350 PCB design by Alex-Hermeling, published on GitHub. It is a 2-layer board measuring 77 × 60 mm, with 3 components from 3 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the AT28C64B-15PU. By type, the board carries 2 ICs and 1 connector.

From the project

A repo to store all of the KiCad files for this project

V0.1 has many problems with the schematic and the PCB design. First, the schematic contains a mistake with both XOR segments. A wire is supposed to go from the right resistor under Q10 to 5V and from the right resistor under Q14 to 5V. Also, the design of the PCB is flawed because it is hard to hand-solder. While designing this PCB, I was too focused on saving space, which should not have been the case for the first version. The input and output holes were too small to fit any regular-size wire. All of these problems were fixed in V0.3.

EEPROM Programer: common questions

What microcontroller does the EEPROM Programer use?

The EEPROM Programer is built around the Pico, from the RP2040/RP2350 family.

How big is the EEPROM Programer PCB?

The EEPROM Programer measures 77 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EEPROM Programer?

3 components, from 3 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 EEPROM Programer design files?

From the Alex-Hermeling/Transistor-Calculator 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 EEPROM Programer design in my own project?

The repository has no license, so all rights stay with Alex-Hermeling. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the EEPROM Programer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
