Oaqmvgin Chain Joystick Hall-Effect Joystick/Z Input UART Serial Link cascade enables multi-device networks; two HY2.0-4P expansion interfaces grow series applications now.

It also integrates a programmable RGB LED for status indication and interactive display. Suitable for human-machine interaction, robot control, and other applications. The device uses a Hall effect electromagnetic joystick, achieving high- control by detecting changes in the magnetic field. It features non-contact operation, wear resistance, high , and strong anti-interference capabilities, ensuring product stability and long lifespan. The ChainJoystick is a high- Hall effect electromagnetic joystick input node. It supports three- control signal input, including analog input for the axes and digital input via buttons for the Z . The ChainJoystick series of devices integrates the STM32G031G8U6 core controller and adopts the UART serial port cascading communication protocol. Through two HY2.0-4P expansion interfaces, more Chain series devices can be added to build richer interactive applications.
