Jrifedptry 6-In-1 USB to UART Serial Port Module Kit USB TTL 485 232 Free Conversion CP2102 USB to TTL TTL to 232

Small size: The circuit board is small in size, less than the size of a USB flash drive, and only occupies the width of a USB port. Even on those laptops where the two USB ports are very close together, you can easily place two side by side. 3.3V and +5V compatible: This product supports 3.3V voltage. Nowadays, many high-end microcontrollers, such as ARM, STM32, , etc., use 3.3V voltage. Other modules are only compatible with 5V voltage, they do not have 3.3V voltage output function. Fully supports Win8, Win7, WinXp, Win2K, WinCE, Linux, systems, 32-bit and 64-bit systems. CP2102 core chip: CP2102 is a USB to serial port chip with , stability, and performance far exceeding that of cheap similar chips, such as PL2303, FT232, CH341, etc. Power supply output: This module can be used to power the microcontroller system to facilitate debugging. 5V-500mA or 3.3V-100mA.
