Small atmega 2560 board

Post by Peter »

I have an ez*2 with a promini and sensor board.
But I want to hookup at a osd, GPS and FrSky telemetry.
Using the telemetry for a vario. GPS is now i2c, osd and telemetry needs serial.
So I am looking for a small atmega 2560 I think. Max 4cm wide.
Does anybody know one? Preferably without sensors.

I have a naze32 acro as alternative, but that does not have the airplane rth software afaik.

Thanks, it's an old flysky receiver that I converted. Reused the pin headers.

I too would like to see smaller Mega boards with 10dof sensors. One problem seems to be fitting connectors for all i/o onto such board? (crius mega aiop has switched to 1/20" pin spacing headers, not really convenient)

It's a hard to shrink a 10Dof under the standard 50*50 size.

that board is 6x4 cm^2? Not a real improvement over standard 5x5.

It would better fit the ez*2 though.
I am also looking at a naze32. 36x36mm and 2 serial ports when using cppm. Very nice. But it is 3.3 volt and my minim osd and flytron GPS work on 5v. And PatrikE, your great rth software is not ported yet afaik.

You can feed minim osd and flytron GPS With 5v.
A resitor on the rx line on the FC Will limit currant from the other units.
