Vielen Dank genau das hab ich gesucht. Kommen da an VCC überall 3,3v an?
@Lordcyber Sorry, I do not look often at this site. I understand you want to know the voltage of this circuit. The nominal voltage is 3V3, but in the datasheet of the two part you can see the following: STM32L051: 1.65 V to 3.6 V power supply and the RFM95W: 1.8 to 3.7 V. So roughly you can apply 1.8 to 3.6 V. For example I do use the LS14500 cell to connect directly to this board and this works fine.
