MCU STC Auto Downloader / Programmer | USB to TTL DownLoad Cable | Dual Voltage 3.3V, 5V Universal

Product Description:

Programmer for MCU STC microcontrollers. USB to TTL converter module: USB to TTL converter module based on the CH340DC chip. It is a simple module for communication via USB with devices in the RS232 TTL standard. The system also allows you to program the MCU STC microcontroller. The module provides a voltage of 3.3V and 5V. It also supports MSP430 BSL (only with MspFet software). The system ensures high data transmission up to 115200. The converter can program the microcontroller of the STD12, STC11, STC15, and STC51 series.

Additionally, a 500mA fuse has been used in the system to protect the connected system against damage. The fuse is resettable. The module has an aluminum housing that protects the converter. The system also has a LED indicating the operation of the system.
