    Hi! Have been looking for some info on this board as the datasheet appears incomplete

    1. Does the carrier come with a JST-JST battery cable? According to you connect the carrier to the mkr by cable for the battery connector (didn’t realize) - the Opla kit comes with the cable it seems but wondering about the plain Carrier board

    2. What battery does it use - 18650 flat or button top? Protected or non-protected?


    Update: zooming in on reveals a Roofer INR18650-2500A which seems to be a flat top, at least.... it would appear that the mkr IoT carrier batter connector just passes straight to the mkr jst connector. I’ve been using a flat pack LiPo with my MKR NB1500 and (I believe) that is protected... but it’s a rather vague description unfortunately
