Grabbed a couple more nodeMCU’s for projects I have in the pipeline, but I didn’t realize that this has a different form factor to the other type (like your SKU 26133). This PCB is quite a bit larger. I had thought the only difference was the serial comms IC (CH340 vs CP2102) … wish I’d gone for the other now as these will be harder to fit in the enclosures I have. Also the assembly on these looks ever so slightly artisanal, if you know what I mean. Oh well, I’ll make it work!
