STM32 Usb Based firmware microcontroller for any Amiga internal keyboard adapter

STm32-to-Amiga-Local-Keyboard adaptER =====================================

The STALKER adapter board enables connecting USB HID keyboards to your Amiga 1000, Amiga 2000/3000, Amiga 4000/CD32, Amiga 500, Amiga 1200 and Amiga 600 and it is based upon 32-bit STM32 microcontroller.

The STALKER provides built-in USB stack which enables USB HID keyboards support without the need for installing additional AmigaOS software drivers. The whole installation process comes down to simply connecting a STALKER adapter and plug to the keyboard port of your Amiga 1000, 2000 or 4000 externally, or…

StandAlone-Adapter: common questions

What microcontroller does the StandAlone-Adapter use?

The StandAlone-Adapter is built around the STM32F401RBTx, from the STM32 family.

How big is the StandAlone-Adapter PCB?

The StandAlone-Adapter measures 78.7 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the StandAlone-Adapter?

51 components, from 24 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 StandAlone-Adapter design files?

From the gianlucarenzi/stalker repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the StandAlone-Adapter design in my own project?

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

Can I test firmware for the StandAlone-Adapter 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.
