Someone made an ESP32 controller where the game lives on the pad itself

A Kickstarter campaign is funding the Smart Joystick Controller, an ESP32-S3-based handheld device featuring a 2.0" color LCD, dual analog sticks, haptic feedback, IR transmitter, and USB-C. It can function as a standalone handheld game console, a controller for external displays, or a remote for drones and robots. Compatible with Arduino, ESP-IDF, and MicroPython, it's fully programmable. Early bird pricing is $55, with standard pricing at $59, though standard crowdfunding risks apply.
