Updating Firmware at the Edge Using Amazon FreeRTOS – Now Digi-Key Technical Library

by

Amazon FreeRTOS helps developers simplify the process of connecting an Internet of Things (IoT) device to the cloud. However, even with a simpler cloud connection, a major hurdle that many developers will be facing is how to update their devices’ firmware in the field.

Firmware updates are often done using a bootloader which can come in many different forms based on the device architecture and the communication peripherals available. Since bootloaders are commonplace and included in nearly every embedded system, developers need to leverage existing solutions instead of developing one from scratch. This allows them to spend more time focused on their own product’s differentiators and features.  http://bit.ly/2wAFeRg

How to Optimize Energy Use in IoT Edge Devices – Just Published by Digi-Key

by

Jacob Beningo explains:  When designing battery-powered Internet of Things (IoT) devices, a prime objective is to extend the time between recharges, or in the case of standard cells, the lifetime of the battery. There are many traditional approaches, but these lack the necessary system level perspective needed to fully optimize a design.

For maximum use of available battery power, the IoT device needs to be optimized as an entire system and not as a collection of unrelated components. This article will examine the latest techniques and technologies available to optimize an IoT design’s energy consumption and how best to apply them.  http://bit.ly/2whM7a0

Now in the Digi-Key Article Library: How to Isolate High Voltages in Single-Supply Industrial Robotic Systems

by

High voltage differentials in industrial automation systems can create havoc without the proper application of galvanic isolation techniques

The connection of multiple systems in industrial automation applications provides many benefits, but when there are high voltage differences between these systems, designers need to manage voltage inconsistencies. These include large differences in system grounds. The hardware techniques that tackle these analog and digital galvanic isolation challenges have optic, magnetic, and capacitive barriers. The types of isolation transmission signals include analog signals, power, and digital signals.  http://bit.ly/2HXUbSw

New From Digi-Key: Take Advantage of IC Load Switches’ Features to Safely Minimize Power Consumption

by

Industry Expert Bill Schweber Explains…..

To minimize power consumption, a simple MOSFET is often used to gate power to unused circuits. However, a better option is to use a load switch as it has additional functions to handle the many subtleties and vagaries of power rail management.

Load switches are offered with an array of performance parameters and ratings from multiple vendors, which enables a good fit between application priorities and available parts.  Schweber’s article is featured on Digi-Key’s website –  http://bit.ly/2HVqSvj

New from Digi-Key: Add Firmware Security to an IoT Design with a Single Chip

by

In an increasingly security aware IoT landscape, IoT developers face seemingly conflicting demands for rapid development and tighter security for all phases of the application lifecycle. While many emerging solutions come with mechanisms for encryption, IoT designs need to be able to address a wider range of security threats.

To allow them to do so, IoT applications need to build on a root-of-trust established with secure boot and firmware updates at the device level.

This article will show how, using a single security device from Microchip Technology, developers can rapidly implement a range of security mechanisms needed to ensure IoT application security.   http://bit.ly/2rc7t5M
