About the Sdfsdf PCB

Sdfsdf is an open source Raspberry Pi PCB design by lightningspore, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 19 components from 9 distinct parts.

Its main chip is the WAVESHARE_LCD_BUTTON_BOARD_1.3IN, from the Raspberry Pi family. Other key parts include the LuckFox_Pico. By type, the board carries 8 resistors, 2 ICs, 2 connectors, 2 jumpers and 1 capacitor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Use an air-gapped Raspberry Pi Zero to sign for Bitcoin transactions! (and do other cool stuff)

SeedSigner code fork: https://github.com/lightningspore/seedsigner/tree/0.8.5-luckfox

Previous Iteration: LuckFox Pico Pro Max (More Flash, SPI Flash)

These example builds can build a device for around $60.

Replace /dev/diskX with your actual SD card device path.

Sdfsdf: common questions

What microcontroller does the Sdfsdf use?

The Sdfsdf is built around the WAVESHARE_LCD_BUTTON_BOARD_1.3IN, from the Raspberry Pi family.

How big is the Sdfsdf PCB?

The Sdfsdf measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sdfsdf?

19 components, from 9 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 Sdfsdf design files?

From the lightningspore/seedsigner-luckfox-pico 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 Sdfsdf design in my own project?

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

Can I test firmware for the Sdfsdf without the hardware?

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