Zephyr has a lot of tricks up its sleeve and most recently I used it to enable power regulators on a custom Golioth board. Perhaps the most interesting part of this is that it can be done entirely with the configuration code, without needing to dive in to any of the C files. And as […]
In this post, we look at the absolute minimum current drawn by the nRF9160 SOC when peripherals and modems are turned off, using the Power Profiler Kit 2 (PPK2) to measure the current consumption.
IoT devices are usually battery-operated and, more often than not, need to run on a single battery charge for multiple years. Before we know it, MCU power consumption becomes a huge deal when developing a product. Measuring power consumption of an MCU can be challenging since it does not depend on just one thing. It […]
How full is your battery? How much current is your USB device drawing? What is your energy usage of your bank of devices? Gaining granular feedback on your electricity usage is a valuable tool. We have previously discussed this as part of our AC Power Monitor. We took that concept and extended it for DC […]
This IoT Power monitor is the newest reference design from Golioth. Quickly deploy a fleet of devices for monitoring electrical equipment to increase efficiency and monitor machine outages.
How do you ensure you achieve the lowest possible power with your Cellular IoT Devices? We held a webinar on January 18th, 2023 where we tackled this question.
The Golioth team will team up with Jared Wolff of CircuitDojo to talk about reducing power in cellular based designs connecting to the Cloud. Use the form on this post to take part in the webinar.
Manufacturing is marathon, not a sprint. Chris Gammell walks through five phases of IoT device production, discussing what’s involved in each step and how Zephyr RTOS can help during his talk from the 2024 Embedded Open Source Summit.
Sandra Capri, CTO of Ambient Sensors, writes about building a Bluetooth Mesh demo where a cellular-based Thingy91 unit acts as a bridge to the Golioth Cloud.
The RAK5010 is a cellular board based on Quectel’s BG95 modem (Qualcomm chipset). A Nordic nRF52840 microcontroller “runs the show”, connecting to the modem via UART. This is a nice combination for a number of applications like remote sensing, application tracking, and Bluetooth <> Cellular gateway. Let’s walk through the process of developing for this board in the Zephyr RTOS.
