Icarus IOT Board

Post by dkkmrohn »

Everything has been working great up until tonight using Icarus IoT. I got a new, smaller 600mAh lipo battery. Reading the datasheet I saw no mention of mAh minimum. However, I was aware from the circuit dojo version they said nothing less than 300mAh.

After I plugged in the smaller battery I didn't see app running. I went back to USB and 1800mAh battery and everything was fine except for one thing- No charge light came on :-(. Could I have browned out the charge circuit? I figured 600mAh was enough head room.

Please let me know your thoughts.

Thanks
Dave

Just checked. The new battery I thought was from same supplier. Polarity was inverted. :-(. I assume I damaged a component with the charging circuit when I plugged in USB. Nrf9160 SiP works fine.
