Reference Design
The One-Channel Hub reference design provides LoRaWAN network connectivity utilizing the lowest cost solution available by incorporating Semtech's LoRa sub-GHz transceiver with a low cost Espressif MCU, and adds an LCD display for simple user operation. Currently compatible with SX1261, SX1262, SX1268, LR1121(for dual SF-operation) and LLCC68.
With the LR1121, the One-Channel Hub supports two SFs in parallel. This enhances versatility of the network, with the possibility to connect very remote sensors, using SF10 for example, as well as nearby sensors, i.e. using SF7, providing lower power consumption or more data throughput.
