Hi all,
I am using SIM908 modem. I have some issue with SIMCARD. I connect LED to pin NETLIGHT (SIM908)
After power on SIM908 modem, I saw this LED blink. SIM908 seem ran. But Voltage on SIM_VDD pin: 0V. BUt as follow SIM908's datasheet, voltage on this pin:1.8V or 3.3V.
I can explain that.
Pls, help me.
Thank you very much,
