Function introduction: 1.Power supply output: You can supply power to the microcontroller system through this module, which is convenient for debugging. 5V-500mA or 3. 3V- 100mA.(3.3V and +5V Compatible: This product supports 3.3V voltage.) 2.Overcurrent protection: The onboard resettable fuse will not damage the circuit board or computer even if the positive and negative poles are short-circuited. If there is a short circuit or the current exceeds 500mA, the fuse will automatically open. When the circuit returns to a non-short circuit state, the fuse will return to normal. 3.Transceiver indicator: When there is data on the sending line or the receiving line of the serial port, the transceiver indicator on the board will light up, which is convenient for debugging. 4.TTL level interface: It can be directly connected to a microcontroller or other embedded devices, such as 51, STC, AVR, ARM, FPGA, etc., without conversion. 5.RS232 level interface: connect to a computer or RS232 level serial device. 6.RS485 level interface: automatic sending and receiving control, no need for sending and receiving control lines, default receiving state, when there is data on the sending line, it is changed to sending state. 7.Free mutual conversion of four levels: circuit design, USB, TTL, RS232, RS485 free mutual conversion, physical switching through switches, convenient and reliable, no interference. 8.High-speed communication: baud rate up to 2Mbps. 9.DTR and RTS signals: The module leads out the DTR and RTS signals in the serial port and is multi-functional, and supports MSP430 microcontroller BSL download, etc. Package includes: 1 x CP2102 USB-UART Converter 1 x 12pin Female to Male Cable 1 x USB Extension Cable
