Adafruit Mini I2C Gamepad with seesaw - STEMMA QT / Qwiic Breakout Board - 2-Axis Joystick & 6 Buttons
- ?? Core Functions and Features
- Integrated joystick and buttons: The board features a 2-axis 10-bit precision analog joystick and 6 microswitch buttons (4 large buttons arranged in a rhombus shape, and 2 small buttons located in the center, corresponding to the Start and Select functions).
- Seesaw technology core: The board is equipped with a pre-programmed ATtiny816 microcontroller that runs the seesaw firmware. It reads the analog signals from the joystick and the button states and converts them into a clean I2C interface, so even if the main controller does not have analog input pins, it can still be used normally.
- Optional interrupt pin: An optional IRQ interrupt pin is provided. When a button is pressed or released, it can trigger an interrupt to notify the main controller, thus freeing up processor time for other tasks.
- Flexible I2C address: The default I2C address is 0x50. The board has two address jumpers (A0 and A1), allowing you to cascade up to 4 of these game controllers on a single I2C bus.
- Plug-and-play design: Using standard STEMMA QT/Qwiic connectors, it supports quick connection without soldering, and can be easily integrated into the existing I2C ecosystem.

?? Main Applications
Game Controller: Create a compact controller for your DIY game projects or retro game consoles.
Robot Remote Controller: Use as a direction and function control handle for robots or remote-controlled vehicles.
User Interaction Interface: Provide an intuitive human-computer interaction solution for any embedded project that requires direction control and multiple buttons.
Product Features
No burden on the main control: I2C interface means you don't have to sacrifice any valuable GPIO or analog pins, and even if the main control itself doesn't have an ADC, it's no problem.
Advantages of seesaw firmware: Offload the complex joystick reading and button debounce work to the onboard coprocessor, allowing the main control to focus on more important tasks.
Easy Expansion: Through I2C address jumper, you can easily connect multiple game controllers to the same main control to achieve multiplayer games or multi-axis control.
Complete software support: Provides a complete Arduino library and CircuitPython/Python library, along with detailed usage tutorials, making your development process easy and fast.
?? Packaging List
