Three LED indicators assist programming and debugging, highlighting power status and TXD and RXD data transmission, alongside an operating level switch allowing the user to select 3.3V or 5V.

Package contents

  • 1x USB TO TTL converter
  • 1x 8-pin TTL "fool-proof" wire

Please Note

  • No USB cable included
  • This converter is designed to work on TTL level, NEVER connect it to RS232 level to avoid damage

Pinout

The pinout is printed on the converter, which is mapped as follows:

5V 5V output
VCC 3.3V or 5V output, configured by switch
GND Ground
TXD Connecting to MCU.RX (signal direction: MCU.RX << FT232 << PC.TX)
RXD Connecting to MCU.TX (signal direction: MCU.TX >> FT232 >> PC.RX)
RTS Connecting to MCU.CTS (signal direction: MCU.CTS << FT232 << PC.RTS)
CTS Connecting to MCU.RTS (signal direction: MCU.RTS >> FT232 >> PC.CTS)

System Support

The converter is compatible with popular systems such as Win7/8/8.1/10, Mac, Linux, Android and WinCE.
