USB Flash/EPROM Programmer: common questions

What microcontroller does the USB Flash/EPROM Programmer use?

The USB Flash/EPROM Programmer is built around the Pico, from the RP2040/RP2350 family.

How big is the USB Flash/EPROM Programmer PCB?

The USB Flash/EPROM Programmer measures 148.8 × 132.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the USB Flash/EPROM Programmer?

121 components, from 38 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 USB Flash/EPROM Programmer design files?

From the robsonsmartins/usbflashprog 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 USB Flash/EPROM Programmer design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the USB Flash/EPROM Programmer 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.
