The Edgeberry Base Board provides essential additional functionality for deploying the Raspberry Pi Model B as an IoT edge device in a real-world environment.
- 12 to 24VDC input power supply for reliably powering the device with up to 3A at 5V.
- Indicators and button for providing status feedback and device interaction
- Expansion slot for Edgeberry Hardware Cartridges
- Robust enclosure for withstanding the environmental challenges of the real world
Edgeberry Device Software
For using your Edgeberry hardware with the Edgeberry ecosystem (e.g. the Edgeberry Dashboard), you'll need to install the Edgeberry Device Software. Follow these installation steps. If you have different plans with this board, this software is not required for correct operation of any of its hardware components.
(re)Writing the EEPROM
[!important] When you purchased the Edgeberry Hardware, the manufacturer has written the EEPROM. If you are the manufacturer, or you're hacking your Edgeberry board, then continue with the following steps.
- Close the
write protectionjumper (JP1) on the Edgeberry Hardware to enable writing the EEPROM - Download and build the Raspberry Pi Hat eeprom utils on your device
- Make the EEPROM file from the eeprom_settings.txt using
eepmake
e.g.$ ./eepmake eeprom_settings.txt edgeberry.eep - Flash the EEPROM using
eepflash.sh
e.g.$ sudo ./eepflash -w -t=24c256 -f=edgeberry.eep - Now
rebootthe device and check the device tree for your hat's settings
e.g.$ cat /proc/device-tree/hat/vendor)

Questions
How big is the Edgeberry PCB?
It measures 135 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Edgeberry use?
57 parts, built around the LM2596S-5.0, 24LC256-I/P, BC547 and SS54. 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 Edgeberry KiCad files?
From the Edgeberry/Edgeberry-Baseboard repository on GitHub, at the commit this page was made from: the board is Edgeberry.kicad_pcb and its schematic Edgeberry.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Edgeberry design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
