# Hardrock-50 Remote Display
|
|
|
|
The Hardrock-50 is a 50W power amplifier for amateur radio QRP transceivers. It has a display showing valuable information like the selected band, the SWR, power, temperature etc. Since I am using the HR50 in a remote station, I cannot directly access those information via the display.
|
|
|
|
However, the HR50 offers serial communication via a USB port. This project tries to solve this problem with the help of a separate, wifi enabled hardware display. It consists of the following two components:
|
|
|
|
* Heltec ESP32 board with display
|
|
* a python flask application, which represents the communication via the serial interface in the form of an API
|
|
|
|
This diagram shows which components are required and how the communicate:

This is how the display looks like in action:
