2 CH341 Programmers USB To UART IIC S PI I2C Converter Parall

Detailed Information About The Product:

product description:
1. The CH341USB conversion module is equipped with the CH341A chip. CH341A is a USB bus adapter chip which provides asynchronous serial ports printing ports parallel ports and commonly used 2-wire and 4-wire synchronous serial interfaces through the USB bus;
2. This module can be used for serial port expansion 12C interface EEPROM and S PI interface FLASH and STC microcontroller programming program debugging data acquisition flashing etc.
Product name: CH341 module
Color: blue

Interface Description:
1. I2C/SP and EPP/MEM parallel port mode the shorting cap is inserted into I2C/S PI D1 red light is always on;
2. UART mode short-circuit cap is inserted into UART D2 blue light is always on;
3.12C interface and UART interface;
4. The output voltage VCC and signal level select SP interface insert 2 short-circuit caps at the same time and the second is 5V;
5. Output voltage VCC and signal level selection when two short-circuit caps are inserted into the 3V3 terminal at the same time it is 3.3V;
6. The printing port and EPP/MEM parallel port the screen printing on the back of the board is the definition of EPP/EMEM parallel port.
