3. ESP32-GATEWAY power supply and consumption
ESP32-GATEWAY typically consumes around 50mA of current depending on the software. The board
can consume much less (uA) using the ESP32 power saving modes.
The absolute maximum power ESP32-GATEWAY can draw from the power supply would be the
determined by the maximum input of the regulator on the power input line. Of course, consider that on-
board peripherals and the main module would use some of that current. When you power the board
from either the USB or the +5V pin of the CON1 header → the regulator is TPS62A02ADRLR can
output maximum 2000mA continuously.
