The nRF9160 Feather by Jared Wolff (aka Circuit Dojo LLC) is an electronics development board. It features the nRF9160 by Nordic Semiconductor. This part is capable of both CAT M1 LTE and NB-IoT for communication with the outside world. It’s compatible with the Zephyr RTOS which is fully baked into Nordic’s nRF Connect SDK. Other toolchains and languages coming soon to a Github repository near you.
The nRF9160 Feather is a true Feather, and then some, board. As you would expect, It works well across both USB and LiPoly batteries.
The board is designed to be nice to your batteries. Not only can you take advantage of Nordic’s advanced power states, but you can also put the device into a low power standby state. Laboratory measurements are putting that mode at about 2µA of current. 2µA!
The nRF9160 Feather is also designed to take harness every last mW your battery has to offer. That means from full-to-empty it’s using every last mW your battery has to offer. It runs at 3.3V and can support and work with most Featherwing boards!
The nRF9160 Feather is CE, FCC & ISED compliant. It’s also authorized for use on the Verizon network!
You can load your applications directly to the nRF9160 Feather without an external programmer. That’s right, there are no extra costs associated with getting started with your nRF9160 Feather.
We’ve tweaked the MCUBoot boot-loader and command-line tools to boost loading speeds by 10x. This means loading via the boot-loader is nearly as fast as using an external programmer!
The nRF9160 Feather has been reviewed and the results are in.
It now has the Open Source Hardware Association stamp of approval!
That means you’re able to view the source and build on the design yourself. All the Eagle files, PDF schematic, and 3D files are available for download today at the documentation website. (see below)
Documentation is readily available and you can access it on docs.jaredwolff.com at any time.
Hardware is licensed with CERN 1.2, firmware with Apache 2.0, and documentation with CC-SA-4.0.
The nRF9160 Feather runs on the up-and-coming RTOS. Combined with Nordic’s nRF Connect SDK and you have full-fledged support. More development ecosystems coming in the future…
nRF9160 Feather used an external active antenna. That means that it will work with most ceramic antennas that look like the one below.
You also have the option to purchase a pre-verified module. Not all GPS antennas are made equal. Go with the included one and you’ll be ready to rock.
Here are some additional antenna specs:
Start your asset tracking projects off on the right foot with the nRF9160 Feather enclosure. It pairs perfectly with the GPS antenna and a 18650 battery cell. (not included). Check out the photos and details below:
The case has a few features you may find handy:
Order it with your nRF9160 Feather and make the package complete! It comes in a kit including the 18650 holder enclosure and PH wire assembly.
Connect to your PC for power and USB-to-UART with this cable.
