TheDWM-S90S LoRa base station module (SPI) is a series of gateway communication modules that comply with the LoRaWAN international communication specification. The module is packaged in a stamp hole and provides an SPI communication interface, which can be embedded on the user's main board, so that the user's main board has the function of LoRaWAN gateway.
DWM-S90S supports 8 simultaneous uplink channels, EU433/CN470/EU868/US915 multi-band optional, allowing access to various LoRa applications. The gateway module can be connected to the standard LoRaWAN core network server, allowing users to easily and quickly access the IoT system.
DWM-S90S series is based on SX1301+SX1255 chip combination, supports LoRaWAN standard protocol Class A/B/C equipment, has 8 uplink channels,1 downlink channel, the maximum transmit power is +27dBm, and the maximum receiving sensitivity is -140dbm.
