Requires an M5Stack Cardputer ADV device and a USB-C cable for flashing, an SD card and second screen are optional.
Purplx is custom firmware that turns an M5Stack Cardputer ADV, a small handheld device built around an ESP32-S3 chip, into a self contained little computer with a cyberpunk theme. The README is clear that this is not a hacking tool, it is more like a full operating system packed with games, survival information, everyday utilities, and a way to launch other firmware without losing your place. It supports an optional second screen wired in alongside the device's built in display, so bigger apps get a proper screen while a smaller panel keeps showing quick status details. Ten playable games are built in, including Snake, Tetris, Chess, Checkers, Pong, 2048, Wordle, Conway's Game of Life, and an original roguelike called Netrun with procedural levels and permanent death. There is also a tamagotchi style virtual pet that keeps getting hungry, bored, and tired over real time, even while the device is switched off. For situations without internet or phone signal, Purplx stores an offline survival guide covering first aid, finding water, starting fires, useful knots, signaling for rescue, and navigating without GPS, all built into the firmware itself. It also includes a Morse code trainer that can transmit messages using the screen's backlight and speaker, a continuous SOS beacon, and a short library of plain English lessons explaining how WiFi and Bluetooth attacks work along with the legal ways to practice them, like bug bounties and competitions. A standout feature is a WiFi based radar that can sense a person's presence by watching how ambient WiFi signals get disrupted as they move nearby, using no camera or microphone at all. Rounding things out are everyday tools like a clock, flashlight, dice roller, calculator, unit converter, a simple notes app, and a music player for WAV files stored on an SD card. Purplx is written in C++ for the ESP32-S3 platform. To use it you flash it onto a Cardputer ADV over USB-C, and an SD card is recommended for notes and music but is not required for most features to work.
