The DRAWS has an ADC built into it. You are correct that those are brought out on pins “Ain2” and “Ain3”. You can access the values of these in a variety of ways through the lmsensors/hwmon

I will let Anna or Bryan characterize the pins in more detail.

If you are monitoring the supply voltage, that is already handled on the 9-15 VDC input for powering the HAT (and Pi).
There is also a second ADC exposed on the accessory jack.

Re: NWDR's take on Raspberry Pi 3 Model A+?
Not an official endorsement or support, but I have a DRAWS HAT running on a 3A+ attached to a SmartiPi display.

Either is fine. (I also have one running on 3A+)
Follow-ups to the UDRC sub-group.

does it matter if you use a Pi 3B or B+ with the draws hat?

Re: Show US Your DRAW Photos
Correct. The stock power button is a pi hat connected to the usb battery pack.
Based on the angle that also means the draws board should fit easily inside. I'm going to use a laser cutter on the side

Re: Show US Your DRAW Photos
Looking at the photo of the case from the rear, you can see that the Rpi header is occupied by a board with a connector coming from it. That is where you need to install the DRAWS board.

Sorry, I've been kind of slow keeping up with the DRAWS thing. From a quick scan, I see that it interfaces with two radios, has built in GPS and can do digital with any Linux software that will run on

Thanks Johnathan. I’ll be working a things a bit today and this evening.
I’ll mainly be concentrating on D-STAR, YSF and DMR since that’s what I have test gear for.
