MKRWAN1310 Power Consumption

Hi everyone,

I’m new to this forum and looking for advice on reducing the power consumption of my MKRWAN1310 board.

I’m currently using the following code to put the board into deep sleep mode:

#include "ArduinoLowPower.h"

void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(15000);
digitalWrite(LED_BUILTIN, LOW);
delay(15000);
LowPower.deepSleep(180000);
}

I measured the current consumption in deep sleep mode and found that my MKRWAN1310 is drawing 31mA (0.031A). I'm supplying power through the VIN pin (not using a battery), and I noticed that the CHRG LED keeps blinking, while the ON LED remains ON.

I want to reduce power consumption further, ideally below 10mA, and I don’t need power for peripherals like the USB. Are there any possible ways to achieve lower power consumption?

Some of the things I’m considering:

  • Disabling onboard LEDs
  • Disabling other unnecessary components

Any suggestions or insights would be greatly appreciated!

Thanks in advance!
