Schematic v1.2 #51

Closed HDC67 closed 6 months ago

HDC67 commented 1 year ago

Can you add the schematics for v1.2 to the repo please.

Thanks

lewisxhe commented 11 months ago

V1.1 and V1.2 are just more ADC resistors, sorry I can't provide them now because the data has been lost.

HDC67 commented 11 months ago

I find that hard to believe that you have lost the design that you are selling.

Please document it here then?

Still don't have shematic for V1.2 ?

HDC67 commented 10 months ago

Nope

Could you please double check, that the DTR Pin No. 3 from SIM7670E is in V1.2 still connected to the ESP GPIO Pin No. 25? The deep sleep method of driving ESP GPIO 25 HIGH to set DTR Pin high seems not to work properly. The wiring might have changed from V1.1 to V1.2.
