A simple USB to serial converter. Specifications:

  • 3.3V-5V TTL voltages (only RX pin)
  • Converts TTL logic levels to computer RS232 levels
  • Power supplies: 5V, 3.3V, GND (min)
  • RX (3.3V-5V)
  • TX (5V)
  • Features a Reset pin for convenient programming with the Pro Mini
  • Built-in polyfuse (self-resetting fuse) of 500mA for the 5V via USB

Note 1:The pinout is not the same as on our FT232 module which is handy for programming the Pro Mini. Pay attention to the pins if you want to program a Pro Mini with this module!  
Note 2:The voltage of the TX pin is 5V and is therefore only suitable for communication with 5V systems/chips! Use a level shifter or make yourself a resistance divider to go from eg 5V to 3.3V.

The drivers can be found here:

Note: users report that the driver for Mac on both old and new computers may be unstable, read this extra link to get it working. In addition, no drivers need to be installed for MacOS Mojave, these are already present.
