About the Oldskool PCB

Oldskool is an open source ESP8266 PCB design by rh1tech, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100 × 79 mm, with 100 components from 45 distinct parts.

Its main chip is the ESP01 Reset, from the ESP8266 family. Other key parts include the Pimoroni PGA2350, AMS1117-3.3, MW7211A, 74HC4052D,653 and ESP-01v090. By type, the board carries 42 resistors, 25 capacitors, 12 connectors, 8 ICs, 5 jumpers and 5 switches.

It belongs with the iot & wireless and retro computing designs in this gallery.

From the project

RP2350 Based Hardware Emulation Platform

FRANK is a hardware emulation platform built around the Raspberry Pi RP2350 (Pico 2 modules and RP2350A QFN). RP2040 / Pico still works in FRANK's socket, but in practice only a handful of firmware (mainly the older ZX Spectrum cores) still targets RP2040. Everything modern (IBM PC, NES, SNES, Genesis, the DOOM / id Tech 1 ports, FRANK OS, and so on) is RP2350-only.

Oldskool: common questions

What microcontroller does the Oldskool use?

The Oldskool is built around the ESP01 Reset, from the ESP8266 family.

How big is the Oldskool PCB?

The Oldskool measures 100 × 79 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Oldskool?

100 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the Oldskool design files?

From the rh1tech/frank repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Oldskool design in my own project?

Yes, under the terms of its GPL-3.0 license, which rh1tech chose for the repository.

Can I test firmware for the Oldskool without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
