Modul funguje, jak má - podařilo se mi ho zprovoznit v LoraWan síti The Things Network v kombinaci s vývojovou deskou Wemos D1 Mini.
Škoda, že není prodávan na breakout desce (příp. i s anténním konektorem) anebo ve formě shieldu .
Bohužel jsem si při objednání nevšiml, že se jedná se o miniaturní modul s roztečí vývodů 1,2mm; pájení v amatérských podmínkách bylo velmi obtížné. Nakonec se však podařilo :)
