Core Module EA

You can upload the firmware using a Micro USB cable using the HARDWARIO Playground or  Firmware Tool (works on Windows, macOS, and Linux). It is easy to start development on this platform using the HARDWARIO Firmware SDK (Software Development Kit). The SDK offers clean and consistent APIs that allow event-driven programming. These APIs are designed for low-power and battery-operated applications. If you need to debug your application and the logging API is insufficient, you can use an SWD debugger and the onboard 10-pin connector. The Core Module can communicate wirelessly with another Core Module, or you can create your wireless network using the Radio Dongle.
