IMPORTANT! If you are connecting a battery to the board, double-check the polarity of the BAT connector - it is reversed compared to typical battery connectors! Either swap the + and - of your battery or pull the connector's plastic up and put it back in reverse! Connecting a standard Li-Po battery without this precaution would damage the battery charger of the board!
