Radio Dongle EA

The Radio Dongle EA version allows you to connect an external antenna, which can increase the range of the entire radio network up to several times. We also recommend using the Core Module EA with an external antenna for the most demanding conditions with more obstacles for the individual connected devices. This item is fully compatible with the Core Module. It has a 32-bit ARM microcontroller with 192 kB of flash memory and 20 kB of RAM. In addition to the integrated sub-GHz radio for the 868/915 MHz band, it also includes two security chips, giving it enough space for up to 32 TOWER devices. You can load firmware into it via USB using HARDWARIO Playground (it works on Windows, macOS, and Linux).
