This USB to TTL serial adapter module can work with different types of computer systems and drivers. The power LED, TXD LED and RXD LED on the module can help indicate whether it works normally. With the build-in signal voltage switch, when you switch to 5V, the power at TXD and RXD will be 5V; if you switch to 3.3V, then the power is 3.3V. Therefore, if your device can take only 3.3V input, this module is a great choice. A 500mA self-restore fuse is used for over current protection. The module can also be used for general serial applications.
Pin Definition: RXD, 5V, TXD, GND.
With RXD and TXD transceiver communication indicators.
With a build-in signal voltage switch – select 5V or 3.3V for the power at TXD and RXD as you switch.
A female and a male serial port, thus supporting two connecting ways.
- USB-to-Serial Adapter Module x 1
Works perfect as a Pi TTY serial interface.Works on Raspberry Pi for TTY debug or serial interface. Supports both 3.3v (Pi) and 5v (Arduino)
Compatible with Windows 10 / Windows 10 IOT - Not a counterfeit chip! No drivers required, Windows 10 recognized immediately.
Much cheaper solution than the 20.00-30.00 cables that are offered by other vendors.
Well packaged with anti-static bag.
For Raspberry Pi:
TX -> RX (UART0_RX / GPIO15)
RX - > TX (UART0_TX / GPIO14)
GND -> GND
5V - leave disconnected (Possibly could be used Read moreto power the Pi if your source port has the correct amperage >= 2 amp)
