单通道集线器
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 and LLCC68.
