Hola,
Some of you have asked me to send you all the necessary material for the operation. I would like to clarify some doubts in this regard.
I will send the PCB with all the components soldered. For its operation, it is necessary to add at least one ESP32 module. This achieves minimal performance. There are other additional functions that require additional components that are readily available.
In principle, I have not considered the possibility of supplying a complete kit with all the elements, mainly because a PCB can be sent by post as a simple registered letter. If many items are added, it would be necessary to prepare a package with the consequent complications in terms of billing, customs and taxes and I do not have the capacity to do so. Should any kit or equipment vendor wish to do so, I will be happy to provide all the necessary design, knowledge and support. I am retired and I want to continue enjoying without obligations ???.
However, if anyone is having a hard time getting any of the modules, I can gladly get it and ship it to them.
For the operation of the S-meter and SWR meter it is necessary to add an ADC converter module of the type ADS1115 and another one for the operation of the voltage and current meter.
To use Serial port 2 it is necessary to add a serial to USB module.
For the temperature control function of the power transistors and the regulator, 3 probes of the type DS18B20 must be added.
Below this message I add example links to buy these components.
Saludos,
