It connects directly to the host via Tab5 Ext.Port1, enabling a plug-and-play input experience. The module integrates an STM32F030C8T6 main control chip, responsible for keyboard matrix scanning and communication processing. The preloaded firmware supports three operating modes: Normal, HID, and Character, adapting to different interaction requirements. The keyboard adopts a 14 x 5 matrix design, supports multiple simultaneous key presses, and provides a complete set of letters, numbers, symbols, and commonly used function keys such as Aa, Ctrl, Sym, Alt, Tab, Esc, and arrow keys. The device communicates with Tab5 via I2C and provides an independent interrupt pin for low-latency real-time reporting of key events. Two onboard RGB LEDs can be used for full-color status indication. With a compact structure and simple connection method, it is suitable for text input, command interaction, and various portable applications that require a physical keyboard. Features Uses STM32F030C8T6 as the main control chip Designed for Tab5, plug and play via direct connection to the expansion port Three operating modes to meet diverse requirements 14 x 5 matrix, supports multiple simultaneous key presses Complete key layout with various commonly used function keys I2C communication with low-latency reporting through an interrupt pin Onboard dual RGB LEDs for colorful status indication Side latches securely lock onto Tab5; two M3 screw mounting holes reserved on the back Compact structure with strong adaptability for portable scenarios Includes 1 x Tab5 Keyboard Applications Text input Command interaction Portable application scenarios Educational programming and maker projects Specifications Specification Parameter MCU STM32F030C8T6 Keys 70-key keyboard I2C Address 0x6D (default) RGB LED 2 x WS2812E-1313 Interface 2 x 5 PIN header, 2.54mm pitch Standby Power DC [email protected] Operating Power RGB (white) maximum brightness: [email protected] (RGB off): [email protected] Product Size 128.0 x 59.4 x 13.1mm Product Weight 65.2g Package Size 147.0 x 82.0 x 16.5mm Gross Weight 97.4g Learn and Documents → DOCUMENTS Show more
