PCB Update: version 3.2
This new PCB version replaces the deprecated ATmega328 MCU with the ESP32-C3 SoC, improving performance and adding wireless control capabilities. The device will be configured during operation via a desktop application, supporting both USB and Wi-Fi connectivity.
The custom-made bifilar transformer has been replaced with a factory-manufactured Mini-Circuits ADT1-1+ transformer, ensuring higher reliability and consistency.
The toggle switch, which was previously used to power the device on and off, has been removed due to its large size and the complexity of integrating it into the device enclosure.
Note
The source files for the PCB of this version of the device are not publicly available! For purchase inquiries, please contact me directly.

Documentation changes
The Gerbers directory has been renamed to PCB. Gerber, BOM, and schematic files are now located in the PCB subdirectory corresponding to the specific device version.
References to different device versions based on the output amplifier have been removed from the main README. The basic technical characteristics of the device and the PCB manufacturing parameters are moved to the PCB directory and are now stored separately for each device version. A new "Firmware info" section has been added, providing details about the latest firmware version, supported transmission protocols, and configuration capabilities via the user application.
The current consumption test results have been added for PCB versions 1.0 and 3.2, and updated for version 2.0.
The "How to use this repository?" section has been revised to align with the new project structure.
Information about Mini-Circuits has been added to the "Who helped me with the development of the project?" section.
