Forget pulling out a microntroller such as an Arduino Uno for flashing boards without a USB port (i.e. Iskra Mini or Troyka Wi-Fi).

This compact USB-UART Converter will make any microntroller USB compatible.

General Information

This module serves as a bridge between the USB port of a computer and the microcontroller. This allows you to connect any device with a serial interface UART to your computer.

The converter is useful for setting and flashing a Troyka Wi-Fi. Using this tool, you can fine tune Bluetooth and GPS / GLONASS modules through commands. The module is also useful for flashing a homemade Arduino.

Connection

Connect the module to the computer via micro USB cable.

There are a pair of Troyka headers on the module:

Bottom

  • Signal (TX) - digital output USB-UART converter. Used to transfer data from USB to microcontroller. Connect to the RX pin on the microcontroller.
  • Power (V) - connect to the operating voltage of the microcontroller.
  • Ground (G) - connect to the GND pin of the microcontroller.

Top

  • Signal (RX) - USB-UART converter digital input. Used to receive data from the microcontroller to USB. Connect to the TX pin on the microcontroller.
  • Signal (R) - the reset pin.
