Ai-Thinker AiPi-Knob is a rotary encoder screen development board built around the Ai-M61-32S platform. According to the official Ai-Thinker documentation, this Ai-Thinker knob screen dev board integrates a 1.28-inch round display, rotary encoder control, RGB lighting, built-in audio, infrared transmit and receive, download pins, and exposed USB connectivity for richer interactive embedded projects. AiPi-Knob comes with factory demo firmware and is aimed at smart control panels, UI interaction prototypes, embedded display projects, smart home control interfaces, and Ai-Thinker HMI development. The official demos include appliance-style interfaces such as washing machine control, RGB light control, TV control, and air-conditioner control, which makes this Ai-Thinker development board a strong fit for screen-first product ideas.
