Thanks for your answer. Could you spare a link to the dc-dc modules? Some of what I found use the AMS1117, which burns 10mA while the MCU is sleeping For the MP2307 that is used by other dc-dc buck modules I found, I was unable to identify the quiescent current while the MCU is sleeping/idle. Thanks again!
Hi INTP, the voltage will be around 4.8-5.4 V (4 AA), maybe 7.4V (2 LiPo 3.7V) if the ESP does not run stable with a single LiPo.Thanks & best
Are those the voltages you have going into your ESP8266 module?I've been trying to find a concrete answer to the operating range, I have it in my notes as 2.5v to 4.7v
Alternatively, if you have an external, regulated, supply you'd like to deliver directly to the ESP8266, you can supply that voltage through the 3V3 pin (on the I2C header). While this voltage doesn't have to be 3.3V, it must be within the range of 1.7-3.6V.
Are those the voltages you have going into your ESP8266 module?
