Can a Xiao nRF52840/SX1262 presolder stack be used on an Expansion Board Base for XIAO with Grove OLED? I have a Xiao/lora hat stack mounted on an Adafruit Bff module now. But I want to move the stack over to an expansion board base with an OLED. I read that it won’t work with the stack. Just trying to find out for sure before I mess something up. Thanks Cam

Hi there,

Yes, and YES… Works great ,be sure to get the pins right in the sketch, double check them,

LORA + GPS + Xiao +expansion w/OLED and WS8212 LED Strip for status.

Thanks for the info and pics, I appreciate it! I read you could, and I read you couldn’t stack them on the expansion board base.

Hi there,

Sure, NP.
The stacking can be done by putting the GPS on the Bottom too.
Depending on Which Xiao kit you use , it changes slightly. :v:

I’d be careful with this combination. The XIAO nRF52840 is supported by the Expansion Board Base, but the SX1262 stack uses specific pin connections, so it may not be a simple plug-and-play setup. I’d check the pin mapping and physical clearance before moving the stack. The Expansion Base documentation confirms nRF52840 compatibility, but it doesn’t specifically confirm the SX1262 stack.

Hi there,

So, Having done exactly that , NOTHING to worry about, Both are supported, so
I don’t know where you get the “Beware” vibe from… :face_with_peeking_eye:

Not only does it work but , Look Mom, :blush: it has a display too…
Hit the Magnifier up in the corner and search it you will find a video demo and code working a Ping-Pong test between 2 nodes and some Range tests as well.

YOLO

You can use the Other Grove Ports also…add a WS8212 8-bit Strip and use it for status

Have a look at the schematic, You quickly see it is a No-brainer. :brain:

Works on the Smaller Breakable to a shorty :smile:
Grove Expansion as well. and you can add an external display too.
