Serial Basic Breakout – CH340G USB 轉 TTL 轉換模組

SparkFun Serial Basic Breakout 是一款易於使用的USB-to-Serial模組，基於WCH的CH340G IC。它適用於5V和3.3V系統，應在大多數操作系統上自動安裝，無需額外的驅動程序。Serial Basic使用CH340G IC快速輕鬆地將串行信號轉換為USB。它是極受歡迎的FTDI Basic的低成本替代品。

串行基本的引腳排列模擬了數百種FTDI-to-USB衍生產品上常見的DTR / RX / TX / VCC / CTS / GND引腳排列。它還可以用作調試的通用串行設備（例如使用GPS模塊）。電路板後部有一個跳線，用於控制VCC引腳上的輸出電壓。默認情況下，電路板輸出3.3V並具有3.3V信號。將此跳線更改為5V將導致電路板在5V信號的VCC引腳上輸出5V電壓。

SparkFun Serial Basic Breakout – CH340G

The SparkFun Serial Basic Breakout is an easy-to-use USB-to-Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340G IC to quickly and easily convert serial signals to USB. It’s a great lower-cost alternative to the extremely popular FTDI Basic.

The pinout of the Serial Basic mimics the common DTR/RX/TX/VCC/CTS/GND pinout found on hundreds of FTDI-to-USB derivatives. It can also be used as a general serial device for debugging (such as with a GPS module). There is a jumper on the rear of the board that controls the output voltage on the VCC pin. By default, the board outputs 3.3V and has 3.3V signals. Changing this jumper to 5V will cause the board to output 5V on the VCC pin with 5V signals.
