And the topmost pin is pin #1 in the view below, correct?

Thanks @Alex-Kushleyev. I hooked up the voxl2 mini to the lepton breakout via the m0188 board and the voxl2 fails to boot (the first green light just stays solid). The voxl2 boots just fine with the m0188 attached if I try without the lepton breakout attached. Does that point to a power issue re:the 2.8v vs 3v mismatch? Or something else?

@Alex-Kushleyev Actually one follow-up question - just to confirm, J6 & J10 on the M0188 also operate at 2.8v? The lepton board I'm trying to use (https://groupgets.com/products/purethermal-breakout-board) takes 3-5v input. I just checked the Lepton datasheet and was surprised that the minimum voltage is actually 2.8v. Any experience with these purethermal breakout boards or any idea if this setup will work?

Perfect! Thank you @Alex-Kushleyev!

Hello! We are trying to use a M0188 adapter board (https://docs.modalai.com/M0188/#lepton-2---j5-external-spi-to-m0104-j10) to connect two leptons to a voxl2 mini. Are the pinouts for J10 & J5 available somewhere? They are listed as TODO on the linked documentation page above.

Thanks,
Jared
