Product Description
| Product Introduction This module is a gold-plated USB-to-TTL converter, fully compatible with all STC microcontroller series. Unlike the PL2303 solution, it avoids download issues caused by driver differences. It uses a brand-new, original CH340G chip, officially recommended by STC for USB-to-TTL conversions. It eliminates incompatibilities caused by different drivers or computers, and offers high stability. It is widely used for set-top box upgrades, router firmware upgrades, hard drive firmware repairs, mobile phone system upgrades, game console flashing, STC microcontroller program downloads, USB-to-TTL communication, and serial port debugging. |
| Product Features Power indicator light (PWR), TXD, and RXD indicators. Reserved RTS and CTS positions allow for intuitive monitoring of product operation even without a tester. Dual voltage settings of 3.3V and 5V, selectable via a shorting cap. Compatible with XP, Windows 7, Windows 8, and Windows 10. Multiple protections against short circuits, overcurrent, reverse polarity, and high voltage. Golden exterior and high-quality pin headers for increased durability. High and stable performance, fine workmanship, and compact size. |
| Note: 1. The TXD and RXD pins are cross-connected, which is a common mistake for beginners. 2. A cold boot is required when downloading the program. That is, after clicking the download button in the software, disconnect and reconnect the VCC cable. 3. MCUs without a built-in crystal oscillator must be programmed in a minimal system circuit. Note that a crystal oscillator is required. |
