Im Markus from Germany. I want to use the MKR1400 for an IoT Project. I connected over the IC2 Port a temperature sensor, OLE Display 0.96 zoll and GPS. Both sensor are connected to 5 V Pin Port. So far everything works fine while MKR1400 is connected to USB Port and Im able to sent the data to the cloud.
However my intent is to connect the MMR over a LIPO. Therefore I bought over Ebay a LIPO with 3.7 Volt and 2500 mAH. I connected the LIPO to the Port to charge the LIPO which worked well. I can measure with the power meter on the LIPO between 4.0- 4.2 Volt, which look like that the LIPO can be re-charged ordinary.
I encountered now the issue if I operate the MKR over the LIPO only it doesn't work.
- Has someone an idea how I get this device operated over a battery?
- Can I use a simple an other options ?
