CH340E MSOP10 USB to TTL Module Board Can be Used as PRO Mini Downloader, 501 Original

Description:1. The USB to TTL downloader can be used as serial communication, MCU downloader, STM32 downloader, routing downloader, etc.2. The downloader has a USB interface, which can easily extend the download line, while reserving pin arrangement interface to facilitate short-distance download and plug-in.Feature:1. There are not only power supply lamp PWR, but also TXD and RXD indicator lamp, which is convenient to intuitively understand whether the product is working without instruments.2. Support for WINDOWS 98/ME/2000/XP/Server 2003/VISTA/Server 2008/Win7/Win8 32-bit/64-bit/win10 64-bit.3. Small volume and high performance.4.3.3/5V arbitrary selection.5. Micro-USB Interface Data Line.6. With 3.3V voltage regulator chip, ultra-stable work, compatible with 5v, 3.3V MCU program download and debugging.Specification:Material: FR4 + Electronic ElementColor: GreenProduct size: 15.7mm*15.7mm*1.6mm/0.61*0.61*0.06''Product weight: 3g (including packaging)STC MCU Download Mode:1) The wiring is as follows: (only 3 wires need to be connected)TXD Terminal of USB Downloader - > Connect Single Chip Microcomputer P3.0 (RX)RXD End of USB Downloader - > Connect Single Chip Microcomputer P3.1 (TX)GND End of USB Downloader - > Connect Single Chip Computer GND2) The development board or small system is powered by a separate power supply. After connecting the wires, it will be found that even if the switch of the development board is closed, the power indicator lamp of the development board will light up (weaker), which is a normal phenomenon. It is still downloaded by downloading STC series microcontroller through serial port (the power supply needs cold start once).STM32 MCU Download Mode:1) The wiring is as follows: (only 3 wires need to be connected)TXD End of USB Downloader - > Connect Single Chip Microcomputer PA10 (RX1)RXD End of USB Downloader - > Connect Single Chip Microcomputer PA9 (TX1)GND End of USB Downloader - > Connect Single Chip Computer GND2) Development boards or small systems are powered by separate power sources. Or use the USB downloader to provide 5V power supply. In download, boot0 needs to be connected to VCC. After download, GND needs to press the reset key to complete the operation. Support for Win7 32-bit, 64-bit operating system, support Win XP operating systemNote: Please allow 1-3mm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item.
