About the Scorpion card pub PCB

Scorpion card pub is an open source STM32 PCB design by psk7, published on GitHub under the MIT license. It is a 2-layer board measuring 83.1 × 45.4 mm, with 88 components from 45 distinct parts.

Its main chip is the STM32F103R8, from the STM32 family. Other key parts include the EPM3064, MAX3421EEHJ+T, IP4220CZ6, 25LC256T and EXT. By type, the board carries 36 capacitors, 21 connectors, 16 resistors, 10 ICs, 4 crystals and 1 diode.

From the project

Подключается к разъему периферии платы компьютера. Позволяет использовать USB клавиатуры, мыши, джойстики, геймпады.

Подключается к разъему периферии платы компьютера. Позволяет использовать USB клавиатуры, мыши, джойстики, геймпады.

Автономный контроллер USB клавиатуры и геймпада. Не привязан к разъему Scorpion и может быть использован с любым Spectrum совместимым компьютером, использующим стандартную ZX клавиатуру, но не имеет поддержки Kempston Mouse и возможностей, обеспечиваемых периферийным разъемом ZS-Scorpion за исключением клавиатуры и Kempston джойстика.

Scorpion card pub: common questions

What microcontroller does the Scorpion card pub use?

The Scorpion card pub is built around the STM32F103R8, from the STM32 family.

How big is the Scorpion card pub PCB?

The Scorpion card pub measures 83.1 × 45.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Scorpion card pub?

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

Where can I download the Scorpion card pub design files?

From the psk7/scorpion-card-pub repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Scorpion card pub design in my own project?

Yes, under the terms of its MIT license, which psk7 chose for the repository.

Can I test firmware for the Scorpion card pub without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
