Decent USB Host: USB, Wifi and Bluetooth on Atari 8-bit computers

The DecentUSB Host aims at being a low-cost extension for Atari 8-bit computers that brings USB, Bluetooh and Wifi capabilities to the platform.
It's open source both in hardware and software to allow the community to easily build new features.

The device is a multi-function interface to keyboards, gamepads or memory devices in a single board that costs less than $15 to build.

The Raspberry Pi Pico has been a fantastic booster for retro-computer extensions. Its fast PIO state machines and its extremely low price enable applications involving precise timing of signals with a much lower barrier to entry than FPGAs.

Specifically, the Pico-W can act as a USB host, a Bluetooth host, and a WiFi card. By connecting it internally to the relevant Atari 8-bit buses and signals, we can interface modern devices with our favorite retro platforms.
