USB to TTL Serial Module Set – PL2303HX, CP2102 & CH340G | 3-Piece Arduino & Microcontroller Kit

USB to TTL Serial. 3-Piece Set. PL2303HX + CP2102 + CH340G. Arduino & Microcontroller. −40° to +85°C.

The USB to TTL Serial Module Set is the essential maker toolkit for Arduino enthusiasts, hobbyists, and engineers who need reliable serial communication between a computer and microcontrollers — a 3-piece set covering three of the most widely used USB-to-TTL (UART) bridge chipsets: PL2303HX, CP2102, and CH340G. Having all three chipsets means you’re covered regardless of your project’s OS driver requirements or microcontroller compatibility. Each module operates across an extended temperature range of -40°C to +85°C, making them suitable for development, prototyping, and real-world deployment in diverse environments.

Key Features
