how many changes are there from V2 (accept for the obvious lack of arduino board and the new arduino pins?)
thanks
and of course is there a guestimate ETA?

Hi there,
These are the changes:
1. Arduino Mega 2560 directly attachable to the back of the PCB (only one Arduino Mega 2560 Pro (small arduino) needed, no need for Arduino shield).
2. Added input shift registers (74HC165) for the push buttons, the number of Arduino pins reduced a lot.
3. Added output shift registers (74HC595), all LEDs are now handled through 74HC959 shift registers, supplied externally with +5V, no current drawn from Arduino
4. Replaced the Transponder rotary switch with a smaller one.
BOM is pretty much the same, except for the extra 5 pieces of 74HC165 and 3 pieces of 74HC595 shift registers, as well as the smaller rotary switch.
In this version I have also gone with the EC11EBB24C03 dual encoders like in the V2.2 which is much easier and cleaner to install (a bit more expensive though)
I have been doing the last shift register connection, it is ready to be published (maybe next week after doing some more checking's)
Since the radio works with mobiflight, the functionality of the volume knobs and the rest of the radio depends on it. On the PCB, for the volume knobs you can solder either encoders with push buttons or potentiometers to simulate the volume. As far as I know that is not implemented yet in mobiflight (I might be wrong though)
Regards
AlbEagle

thank you so much for the quick reply and the amazing work you do.
will be keeping an eye on the site and order it as soon as it is available.
do you have the part number for the new rotary so I can order it already?

Hi just wanting to check on the pots position and make sure I've got them correct before soldiering. I purchased from the BOM link, I'm just a bit unsure as the pot has less pins than holes on the pcb. Can someone confirm if this is normal? I have photos but not sure how to post here Attachments:

I have photos but not sure how to post here Hi there, In the first picture, those are encoders, the two holes on the other side are used for the push button of the encoders which is optional.  In the second picture, you can use either potentiometers or rotary encoders. if you go with potentiometers, you don't need those two holes, if you go with encoders you can utilize the push button switch of the encoder if you want to (optional).  If you need further info, please let me know Best regards AlbEagle |
