I haven’t gone through these in detail but from a glance it looks reasonable @Andrew

Another question sorry. I’ve been having issues with my gps module. It’s just not picking up sat fixes anymore. I bought a cheap gps unit from a local electronics store on a whim but no idea if compatible with the robo :man_shrugging:

Can anyone confirm by any chance?

No idea. One of the smart twins needs to answer this. I’ll ping.

Might very well be! The only thing I’m not certain of here is the voltage input at VCC. Currently we power the GPS module with 3.3v.

What version of robogotchi do you have? I can get you the pinout from the GPS port to match up.

Thanks for the help. I think the specs on this gps were 3.5v-5v so should be ok.

As for my Robogotchi, i think it’s an early version but will have to check. Got it from fullsendelectric when they had them in stock.

You can use the GPS pinout here to connect it. Tx/rx convention is sometimes backwards (tx/tx rx/Rx vs tx/Rx rx/tx), so flip them if you don’t get data (won’t hurt anything).

The Robogotchi LCD itself should show you satellite lock, and/or the app will.

Funny enough i got my original GPS working by moving it in the enclosure. It was wedged in next to esc and now it’s on top. My next problem is getting enough accuracy from it. It functions at 5hz but I cant increase the baud rate to anything higher than 9600. Is this to do with the GPS unit or a limitation from the robogotchi? Maybe it’s worth trying out my other GPS unit to see if it functions on a higher baud rate.

I am very noob at all of this sorry. Apologies if it’s all been covered and my skum reading missed it.

Thanks all.

Is BN-220 the only GPS module the robogotchi supports, or could I buy a BN-250 or BN-180 from the Metr store and use that instead?

Btw, any update in regards to more robogotchi stock?

This will work.

Chips still in short supply, sorry to say.

Hmm, my BN-180 GPS module doesn’t seem to be picking up any satellites. Granted I did plug it in wrong the first time round, but I don’t see anything burnt. I also tried connecting RX to TX and TX to RX, still no dice. Tried increasing baud rate as well, but no success. :frowning:
