Hi Peter,
I've been away for a while and haven't been able to respond, my apologies.
I have 3 units of Raduino32 v4 PCBs with factory welded SMD components, except the integrated Si5351. And here's the problem: Si5351 is very, very small and difficult to weld at home. Also, it is difficult to find, and if found, very expensive. You could use the v4 PCB and connect the pins with wire-wrap to the connector that goes to the radio (this is what I have done).
Only a few THT components need to be soldered:
- 4x10K array resistor.
- LM7805
- The sockets for the modules.
?
To solve this problem I have added a 7 pin socket to insert a module with Si5351 which are available on Aliexpress at a reasonable price. I have also made other small modifications and corrected small bugs in v5. I was thinking of including the circuit for the S-meter sensor and replacing the LM7805 with a 12v to 5v Hi-Link module. This would be version 6.
This PCB is ready to order, but I haven't done it yet.
?
Schematic and PCB can be obtained here:?
Firmware:?
I was working on version 6 slowly (it's summer) but if there are 3 or 4 interested I can try to speed it up and order the PCBs quickly. I don't win anything, so PCBs cost around € 8 with soldered SMD components. I would add the shipping costs to each country.
Saludos,
