Official Smarian USB Transfer I2c Iic Uart TTL Flash Programming to Upgrade Hardware Software Debugging Ch341ta Serial Port DIY - Parts & Accs -

Features Standard serial port, serial port extension: simulation is used toupgrade the original serial peripheral equipment, or add USB serial port. Hardware debugging: use I2C debug I2C interface chip, burning I2CEEPROM memories and memory. MCU burn: burn through the UART interface to MCU program. Program debugging: through the UART interface program to printinformation, check the program running state. Data collection: through the I2C access to save the sensor data ofsuch equipment. Flash: serial flash, firmware updates, brush TV, routing,motherboard, etc.Curved needle interfacedefinition:The plate adopts6 pin inflection interface, spacing of 2.54 MM, dupont lines to connectavailable:RXD, TXD, GND, VCC, SDA and SCL (small board corresponding location mark)Specifies the following:RXD: input, TTL serial port receiving signals (by MCU TXD).TXD: output, TTL serial signal (by MCU RXD).GND: signal ground.VCC: power supply system, consistent with the conversion chip, power supply,can from the external input voltage, also can be used as output to the outsidepower supply.Serial data SDA: I2C bus (pull up resistors are integrated, the external, noneed to do pull).SCL: the I2C bus is a serial clock (pull up resistors are integrated, theexternal, no need to do to pull).USB2IIC function: SCL SDA GND, VCC don't pick up.USB2TTL function: after RXI TXO GND, VCC don't pick up.Select configuration mode:I2C_EN jumper sub for I2C, disconnect for UART serial portChoosing a configuration output interface level power supply:The VCC jump line configuration, the left side for 5 v power supply, portsignal level for 5 v. The right of 3.3 V power supply, port signal level of 3.3V.Specifications: USB adapter USB2I2C, USB2UART dual function USB turn I2C USB turn UART (TTL), on STC ISP download Integrating with the double function, can be c
