USB TYPE-C to TTL CH340C DC 5V / 3.3V Serial Port Module Development

Product introduction: Product manual: This product is a Type-C to TTL serial port module, using CH340 USB bus conversion chip, with 2 indicator lights on the board, which are communication indicators. Because there is no serial port on our current computer, we generally use a USB to serial port module, with only one purpose, to map the computer #39;s USB port to a serial port. Product parameters: Working voltage: 5V or 3.3V Default working voltage: 5V Working temperature: -40°C~85°C Baud rate: 50~2Mhz Operating system: Windows xp, 7, 8, 10 ISP and communication: Support STC MCU download program Support STM8 download program with boothloader Support Arduino download program with boothloader Support STM32 serial port download program description: V+VCC power supply positive input and output: when the working voltage is 5V, it is the 5V power output, when the working voltage is 3.3V, it is connected to the external 3.3V power supply V- GND Power negative pole: 0V TX data sending end: connect to MCU or target board data receiving end RX data receiving end: connect to MCU or target board data sending end Package Included: 1x CH340C module
