About the SF2000 PCB

SF2000 is an open source ESP32 PCB design by jbilander, published on GitHub under the CC-BY-SA-4.0 license. It is a 4-layer board measuring 111.5 × 84 mm, with 105 components from 42 distinct parts.

Its main chip is the ESP32-C5-WROOM-1U-N8R8, from the ESP32 family. Other key parts include the LM1117-3.3, ABLIC S-1132B43-M5T1U, SN74CBT16211, SN74CBT3244PW and SN74LVC16245ADGGR. By type, the board carries 60 capacitors, 16 resistors, 14 ICs, 13 connectors, 1 crystal and 1 switch.

It belongs with the retro computing designs in this gallery.

From the project

Spitfire 2000, A low-end 42 MHz Accelerator with IDE and 4/8 MB fast RAM for the Amiga 2000 co-pro slot (or A500 through an adapter).

This is WORK IN PROGRESS, a DIY hobby project. If you are going to make and sell boards you are also the one doing the customer support.

The firmware for this board is in a separate repository available here: https://github.com/jbilander/SF2000-FW

SF2000: common questions

What microcontroller does the SF2000 use?

The SF2000 is built around the ESP32-C5-WROOM-1U-N8R8, from the ESP32 family.

How big is the SF2000 PCB?

The SF2000 measures 111.5 × 84 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SF2000?

105 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the SF2000 design files?

From the jbilander/SF2000 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SF2000 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which jbilander chose for the repository.

Can I test firmware for the SF2000 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
