Chain Joystick

SKU:U205

Description

Chain Joystick is a high-precision Hall effect joystick input node in the M5Stack Chain series. It supports three-axis control signal input, including analog input for X/Y axes and digital key input for the Z-axis. The device uses a Hall effect joystick that achieves high-precision control by detecting magnetic field changes. It features non-contact operation, wear resistance, high accuracy, and strong anti-interference capability, ensuring product stability and long lifespan. It also integrates a programmable RGB LED for status indication and interactive display. It is suitable for human-machine interaction, robot control, and other application scenarios.

Chain Joystick integrates the STM32G031G8U6 core controller and adopts the UART serial cascading communication protocol. Through two HY2.0-4P expansion interfaces, it can extend more devices from the Chain series to build richer interactive applications.
