Description
miro EdgeCard 2G4 is a high-performance, fully standard compliant mPCIe 2.4 GHz LoRa®
gateway card. It can run any firmware binary built for Semtech’s 1+3 SX1280 gateway reference
design while providing more features and significant better performance. The powerful ARM-
Cortex M4 190 MHz MCU can run any standard or proprietary MAC-layer protocol using various
combinations of LoRa® and other SX1280-supported PHYs like FLRC, G(FSK), ranging, advanced
ranging and Time-of-Flight (ToF) localization - both indoor and outdoor. The optionally
integrated RF power amplifier provides a maximum transmission output power of up to
20.54dBm. Together with the highly optimized HF paths using low pass and SAW filters the
miroEdgeCard 2G4 allows to build highest capacity gateways which can be placed in high-
density urban or long-range rural environments and connect a large variety of sensors to LoRa
®
and proprietary networks.
Applications can take advantage of LoRa® (long range, robustness against radio noise) and the
huge ecosystem of LoRaWAN® components and infrastructure like gateways, packet forwarders,
network-servers, cloud services and many more. Moreover, existing edge-level network devices
can be easily upgraded to act as a 2401MHz-2479MHz LoRa® gateway. Any host system capable
of USB CDC is supported. Each Gateway module offers three receive channels and a single
dedicated transmit channel. This allows to receive data from multiple devices on different
channels at the same time.
