Unit JoyStick2

SKU:U024-V2

Description

JoyStick2 Unit is A high-precision hold-electromagnetic rocker control unit that integrates a joystick control signal acquisition firmware using the STM32G030F6P6 microcontroller. The unit communicates via I2C and supports three-axis control signal inputs, including analog input for X/Y axes and digital input for the Z-axis button. The JoyStick2 Unit uses a Hall effect joystick, which detects magnetic field changes to achieve high-precision control, featuring advantages like non-contact operation, wear resistance, high precision, and strong anti-interference capabilities, ensuring stability and long service life. Additionally, the device is equipped with WS2812 RGB LEDs for status indication and interactive display, and a reserved STM32 firmware upgrade interface for easy firmware updates. This product is suitable for applications like game control and robot operation.
