Stratus Pro Power Analysis

Lower power design is critical for battery-powered IoT devices, ensuring long operational lifetimes without frequent maintenance or recharging. At Conexio, we have meticulously engineered the Stratus Pro with ultra-low-power hardware, leveraging efficient power regulators, optimized RF circuitry, and intelligent component selection. Our firmware is designed to maximize energy efficiency by implementing aggressive power management strategies, dynamic duty cycling, and deep sleep states.

As a result, the Stratus Pro achieves an industry-leading <10µA power consumption in active sleep mode—one of the best in the market. This seamless integration of hardware and firmware innovations enables our device to operate for years on a single charge, making it ideal for remote and industrial IoT applications where power efficiency is paramount.

Low Power Mode

The low power mode sample application demonstrates how to put the Stratus Pro in the active low power mode and measure the device current consumption using the Nordic's Power Profiler Kit II.

This application also demonstrates the low power hardware design of the entire cellular kit while constantly powered by the nPM1300 PMIC, without having to shut nPM1300 down or put it into shipment mode.

Some of the main firmware components that allow to put the nRF91 into low power state are:

• disabling the serial and logs in the prj.conf

CONFIG_SERIAL=n
CONFIG_LOG=n

• disabling the UART receiver in the platform device tree.

 &uart0 {
	status = "okay";
	/delete-property/ rx-pin;
};
