Chain Key Single-Key Input Node Integrated Programmable RGB LED, with Hot-Swappable Mechanical Keyb
Chain Key is a single-button input node with hot-swappable mechanical keyboard keys, featuring tactile blue switches and integrated programmable RGB LEDs.
Suitable for human-computer interaction, smart home control, and other applications.
Chain Key integrates an STM32G031G8U6 core controller, uses the UART serial cascading communication protocol, and can be expanded with more Chain series devices through two HY2.0-4P expansion interfaces to build richer interactive applications.
