One Watt Product At SSTPL

ioNODE_1W is a compact, low cost, low power wide area network (LPWAN) wireless module that supports the LoRaWAN long range wireless protocol. This new stand-alone module measures just 28*23 mm, is constructed in a metal shielded package and comprises a Semtech SX1272 ultra long range spread spectrum wireless transceiver and STM32 series ARM Cortex-M0 + 32 bit microcontroller (MCU) along with High Performance One Watt PA & Low Power LNA which makes the module ideal for high noise conditions. The ioNODE_1W module complies with the latest LoRaWAN Class A & C protocol specifications, it is simple to access LoRa-WAN IoT platforms.
