TTGO T-SIM A7670E Power Supply Voltage
-
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? -
