"@Colin,

Here's a link to info on the 3dr radios:

RSSI on both ends is done in MAVLINK "radio" packets instead of hardware. The above link could give you some insight to RSSI…"

"@Jani: Many thanks!"

"@Thomas - I'm looking for the schematic for the button board that attaches to the ASM main board that you show. Paul's shows the button board above. I'm interested in the  5 solder pads to the right of the photo on the button board and to confirm…"

"Jani: Is there a schematic for the button board that Paul has pictured above? I'm trying to understand what the 5 pads Paul has marked on the diagram actually are? I'm looking to add some other I2C devices to the I2C port on the Mega 2560 chip? If…"

"@ Paul: Most helpful! I have a couple of I2C devices I want to try out.

@ Jani: Looking forward to the updates. Schematic would be helpful.

Thanks.

Robert..."

"Jani: Is there a schematic for the button board? Does the I2C port come out to the 5 pin connector pads on the button board? If so, what is the pin out?

Thanks

Robert..."

"Colin: What version of Arduino IDE are you using to compile your code? I have 1.5.2 loaded as I'm using if for a DUE based project at the moment."

"Cuprum: Yes, your moded code would be of interest!

Can you explain the antenna tracking pins issue a little more? Maybe a pic? Was it a matter of getting the ardiuno code to match the hardware pins used for the antenna tracking? What version of…"

"Jani: Thanks for the info."

"Jani: Is there schematic available?

Is the I2C port at 5v or 3.3v? I'm interested in hookup up some 3.3v I2C devices to a ASM V1.5 and wanted to know if I would need a level convert like a PCA9306 or TCA9406 to do so.

Thanks.

Robert..."

"Is there a schematic available for the ASM v1.5?"

"Bill: Thanks. Will fire up the RN-XV/3dr radio combo and give her a try. Looking forward to your next app.

What version of firmware are you running on the RN-XV?"

"Bill: Great app! looking forward to your WIFI instructions as I have all of the hardware you speak of for testing etc."

"Colin: Great work!

Do you have a bill of material that goes with the PCB?"
