LoDev S76S

An STM32 LoRa® development platform that's software-compatible with Arm® Mbed™

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.
