Hi everyone, I hope you can advise me on my power situation. I saw a thread about this, but I’m not sure it’s the same.
I have two boards I’m working with, a 19003 and 19007 (I have a few of each), and GPSS on the boards of all of them. I am wiring a switch to these boards; the 19003 boards turn on and off as expected using the JPH 2.0 micro inlet. But the 19007 will not turn on when I use the same switch. When I use the micro on the 19007, I get a rapid red light flash, and there is nothing, no power. When I made a new switch, that is, JPH micro to JPH 'regular" and plugged into (I think) the solar inlet, the unit ran as expected.
The JPH micro to “regular” switch is a micro to the 2000 mAh battery, and then I soldered a “regular” JPH.
So, the question is why, why doest the micro not work on the 19007 boards? Is it okay to use the larger JPH to power the board?
The connectors, charger and voltage regulator circuits on the RAK19003 and RAK19007 are the same.
The battery connector (larger) is only for rechargeable batteries and you should not supply from other sources through this connector.
The solar connector (smaller) is for an external supply up to 5V, this can be a solar panel or an external 5V supply. It can work as well with a battery if the battery voltage is between 3.7 and 5V, but the battery will not be charged when using on this connector.
Your description is a little bit confusing. Maybe you can share more details or drawing where you use the switch, what battery and where you connect it to the Base Board.
Thank you. I think i got the power inputs backwards. I thought the micro was for rechargeable battery. Looks like i need to back to go back to my other boards and fix them.
