OSOYOO SX1276 LoRa Radio Wireless 868Mhz UART Serial Module LoRaWAN Transmitter Receiver + 868Mhz 3dBi SMA Antenna, Compatible with Arduino STM32 51 Single Chip Microcomputer

These are pretty impressive! I've just driven 12 miles. The first mile is through housing and the next over a hill and into sparce countryside. At 12 miles it was loosing about 50% of packets sent. That means that with error detection / correction, a range of 24 miles, non line of sight, is feasible. OK, it's not close to the 200km record for LoRa but it ain't bad!This board takes most of the complexity out of LoRa. At it's simplest just connect them up & data will flow both ways.One Gotcha I found. Connect Tx on the board to Tx, Rx to Rx on your microcontroller rather than the other way around.Altogether i'm very impressed!
