Here is a cool gift idea for retrogaming fans. The PocketStar is a keychain sized gaming console compatible with Arduino. It has Bluetooth and WiFi connectivity and supports multiplayer gaming. It has an ESP32-C3 processor, a speaker, vibration motor, and built-in accelerometer.
The PocketStar has an app store in development. It has a 0.95 Inch OLED display with 94*64p resolution. The battery is rechargeable and lasts up 5+ hours. Like what you see? You can find this project on Kickstarter.
