Changed the power unit to LiFePO4 6000 mA followed by a DC/DC step up 3.2v to 5 v and a charger module So I can charge the device with my phone adapter.
The PMS5003 needs 5v but data lines are 3v3 so no need for level shifter when connecting to the WIO terminal.
because I have only one , I made The WIO terminal ‘clickable’ on the project box
