SZZL M-Kit

The SZZL M-Kit is a compact, USB-enabled device designed for mouse and keyboard emulation with ultra-reliable input handling. Featuring an ATmega32U4, CH340C converter, and MAX3421 host controller, it’s ideal for custom HID projects, USB device integration, and voltage-safe embedded applications.

Features:

- Mouse Emulation: Our prebuilt pcb configuration can replicate mouse and keyboard events, much like a KMBox. With built-in USB capabilities, the M-Kit is programmable to react to various inputs and transmit corresponding signals to a computer

- CH340C USB-to-TTL Converter: Offers stable UART communication, broad driver support for Windows, macOS, and Linux, and efficient handling of data transmission for programming, debugging, and real-time communication

- ATmega32U4 Microcontroller: Featuring native USB support and HID capabilities for direct USB communication, making it ideal for advanced Arduino projects like custom keyboards, game controllers, and real-time data transfer applications

- Onboard MAX3421: USB host controller chip, enabling USB device communication for embedded systems and Arduino projects, used for applications like USB peripherals integration, data logging, and device control

- 74HC4050 Hex Buffer Chip: For robust voltage level shifting, allows for safe interfacing between components of varying voltage levels while protecting microcontroller I/O pins, for reliable signal conversion in electronic and Arduino projects
