Arm Mbed software compatible STM32 LoRa Development platform
LoDev by Ronoth is an open source LoRa® Development board featuring the S76S SiP (system-in-a-package) from AcSip. The S76S is a compact SiP featuring STM32L073 micro-controller, SX1276 LoRa® Radio, and RF matching components, all in a very compact 11x13 mm package that comes with an FCC modular certification. LoDev allows IoT (Internet of Things) engineers and hobbyists to develop their own sensors and devices with long-range connectivity.
LoRa® technology is one of the leading wireless technologies powering the emerging Internet of Things. It is used in tons of cool technologies such as automatic meter reading, smart parking, and even livestock tracking. It has the unique ability to send packets over fairly long distances using minimal power (We’re talking kilometers!). LoRa® technology is perfect for devices that are located far away and need to send small amounts of data.
LoRa® wireless technology is used in industries and use-cases including:
LoDev is perfect for hobbyist and professional engineers to develop their own sensors and devices. It allows rapid development of sensor applications by leveraging the rich Mbed developer community.
LoDev is open-source and made by a hardware enthusiast for hardware enthusiasts. It is breadboard friendly and comes with a ton of software examples to get you started. It was built with the Mbed IDE and community in mind, but will work with any IDE supporting ARM Cortex.
Mbed IDE allows you to easily import the provided sample projects, compile them, make changes and share your projects all inside your browser. Some of the sample projects include:
LoRa® technology is widely applicable in agriculture and environmental monitoring. That’s why we’re offering a weather sensor pledge level. It includes a DHT11 temp and humidity sensor, soil moisture sensor, and light sensor with full source code available as an importable Mbed project to get started.
LoDev can be used to provide endless creative solutions to everyday problems. We built a mailbox sensor switch using a custom 3D printed part that attaches with magnets. This allows us to know when our mail has arrived in real time.
LoDev is the platform of choice for engineers and hardware designers looking to move rapidly into the growing LoRa® ecosystem. LoDev along with the S76S SiP offer a best of breed solution in all key areas.
Check out the S76S comparison chart below for a good illustration of why the S76S is the best LoRa® solution for low TCO and fast GTM.
LoDev is the only LoRaWAN™ compatible development board featuring the S76S SiP.

At the heart of LoDev is the S76S SiP (System In a Package).
When you are looking to use that development board, it is important to consider the cost and time involved in taking a prototype to a custom product. The S76S is the smallest, most cost effective LoRa® SiP that is FCC Certified. It also comes in a friendly LGA package that is much easier to route than fine pitch BGAs, and requires no additional external components outside of decoupling capacitors.

All orders will be delivered to backers using Crowd Supply’s fulfillment service. Delivery within the US is included in the listed price while delivery outside the US will incur the shipping surcharge listed for each pledge level. For more information, please see Crowd Supply’s guide on ordering, paying, and shipping.
LoDev has been through several iterations of development and has been used in the field for many months. We’ve produced dozens of them and have made numerous design improvements to aid manufacturability.
Ronoth, LLC (Formerly Third Venture Inc) is the same team that brought you LoStik and has experience delivering products through Crowd Supply in the past.
There is risk when delivering thousands of units in a timely manner because of component availability and lead times. We already have conversations ongoing with suppliers and have already purchased some key components for an initial production run.

"The module has a receiver sensitivity down to -146dBm, an adjustable signal strength of up to +20dBm, and a range of up to 15km in rural areas, and 5km in urban areas. "
"Die Auslieferung soll im Mai beginnen. Bei erfolgreichen Kampagnen ist die Hardware auf Crowdsupply übrigens dauerhaft nachbestellbar."
"This has an in-built SX1276 LoRa radio, so it makes the whole package really small."

We are a handful of crazy tech entrepreneurs who have a passion for open-source hardware and software. We've worked together for close to 10 years now and have probably had more than three ventures, but we're only counting the best ones. We're always fascinated with the uncountable ways the internet has changed and connected the world around us and continuously look toward new ways we can be a small part of this generations most exciting advancement.
