Overview
FV-1 EEPROM flasher hardware is an open-source printed circuit board by e-zsche, from the e-zsche/FV-1-standalone-programmer repository on GitHub. It is a 2-layer board of 64.9 × 89.1 mm with 22 parts on 44 nets, routed with 213 tracks and 36 vias.
It is built around the 24LC32A/P. Its parts include 8 resistors, 6 switches, 2 capacitors, 2 ICs and 1 diode. It belongs with the interfaces and adapters boards and the RP2040 boards of this library.
Main components
1README
README.mdMicropython FV-1 flasher
Small project for flashing 24LC32A EEPROMs using any microcontroller which has enough flash and is able to run Micropython. Just because, a raspberry pico is used.
Code
Huge thanks to ndf-zz for writing the asfv1 assembler. Without your work this would not be possible. https://github.com/ndf-zz/asfv1/
As shlex is not in the standard Micropython library a copy of the source code is obtained and used for running the asfv1 assembler. To get it running on the MCU one line is removed. So far this does not seem to have an impact when running the code.
FV-1 programs are stored and read with a micro SD-card. All programs have to be in the root directory
and must have the .spn file extension to be found.
Hardware
Everything is run by a Raspberry Pi Pico MCU.
User interface consists of:
- Display
- SD card slot
- EEPROM sockets
- Buttons
Display
TFT display because it is cheaper than an OLED. Has the SD card slot integrated.
SD Card
Connected via SPI. Slot is Integrated into display module.
EEPROM sockets
There are two positions on the PCB. One is for THT chips, the other for SMD chips. SMD socket is the SOIC-8 socket from adafruit
Make sure to insert the EEPROM with the correct orientation!!
Buttons
In total there are five buttons arranged as a sort of D-Pad and a shift button.
Controls:
- up and down for scrolling through file list (faster scrolling when holding shift button)
- left and right for selecting program slot of selected file
- middle button
- start programming (when not selecting slot)
- selecting slot
Obtain SPN files
Writing programs yourself for the FV-1 is good way to get some programs. Info on the assembly language is a little harder to find than info on the FV-1 hardware. However there are some sources inside a forum dating back to 2019:
This is about all the info I could find on the assembly instructions itself...
Another wonderful source of programs is mstratman's collection of programs:

Questions
How big is the FV-1 EEPROM flasher hardware PCB?
It measures 64.9 × 89.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FV-1 EEPROM flasher hardware use?
22 parts, built around the 24LC32A/P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FV-1 EEPROM flasher hardware KiCad files?
From the e-zsche/FV-1-standalone-programmer repository on GitHub, at the commit this page was made from: the board is FV-1_EEPROM_flasher_hardware/FV-1_EEPROM_flasher_hardware.kicad_pcb and its schematic FV-1_EEPROM_flasher_hardware/FV-1_EEPROM_flasher_hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FV-1 EEPROM flasher hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask e-zsche before reusing the design.
