i already use this module to communicate more arduinos togheter, the interface is simple and with perfect line of sight i can communicate with included antenna for around 1.5Km. using internal in a house is perfect for this and with hight baudrate bidirectional. for external usage is good but data trasmitted is low and latency is around 2 seconds, really useful to lanch command to a remote machine. some useful information and command can be found here https://www.elecrow.com/download/HC-12.pdf http://avrproject.ru/112/rf_hc12/2016-01-14_122335_HC-12_v2.3B.pdf attached here is some test of distance
времена немного дольше, чем обычно, вызывают ковиды, но, как всегда, очень приемлемо все по описанию грех не присутствует ряд контактов для остальных отлично
