  Hi, I don't find how "correct" configure the Arduino IDE, to use the full memory including PSRAM of the device.
  Setting it like a generic ESP32 its not valid. This one, includes the ESP32-WROVER-E MCU with 8Mb of PSRAM and 16Flash.

  Selecting a ESP32-WROVER and executing this code ...

  log_d("Total heap: %d", ESP.getHeapSize());
  log_d("Free heap: %d", ESP.getFreeHeap());
  log_d("Total PSRAM: %d", ESP.getPsramSize());
  log_d("Free PSRAM: %d", ESP.getFreePsram());

  The console output is ...

  [D][WifLib.ino:15] setup(): Total heap: 343784
  [D][WifLib.ino:16] setup(): Free heap: 317564
  [D][WifLib.ino:17] setup(): Total PSRAM: 4194252
  [D][WifLib.ino:18] setup(): Free PSRAM: 4194252

  Thanks.

  The ESP is ...

  Hi Lilygo,

  Can you please confirm the acceptable input voltage range of the TTGO T-SIM A7670E?

  From your schematic I see a MT1471 regulator accepting input voltage of 4.5-16V that outputs 4.2V for the modem, this 4.2V is further stepped down to 3.3V unsing the AP2112 regulator.
  Am I correct in saying that the TTGO T-SIM A7670E will fuction with 4.5-16V input on the Vbus pin?
