DC Power Monitor: A Golioth Reference Design

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 […]


Free Zephyr Training Hosted By Golioth, June 7th 2023

Golioth continues to run training for hardware and firmware developers looking to learn more about Zephyr and connecting their devices to the cloud; our last public training had 30 engineers trying out Zephyr and Golioth on accessible IoT hardware. Our next training will take place on June 7th, 2023 at noon EST / 9 am […]


Low Volume, High Mix Mechanical Enclosures for IoT Projects

We’ve been spinning up a large number of reference design hardware units to showcase a number of use cases for Golioth. This means using a number of different internal and external sensors on one unified microcontroller platform using the nRF9160 cellular SIP. Putting these in a case is a challenge since each different sensor suite calls for different openings in the enclosure. This is the story of our journey for a solution that looks great, and is available to us with low-volume order quantities.

Why calibrate? IoT systems work with raw data

One of my first engineering jobs was in the Test and Measurement space. Tracing everything back to standards and calibration is a key part of the process. It takes a long time and is taken very seriously. I had many learning experiences that reinforced the importance of calibration (despite my tongue-in-cheek article title). IoT devices […]
