Developed with Mini PCIe form factor and integrates a 32bit MCU, CypressS6E1C32, and LoRa transmitter Semtech SX1272, ELM series is a LoRa module with standard PCI Express mini card form factor. It fulfills the long distance IoT applications with LoRa wireless technology through AT commands from Windows or Linux platform such as Industrial PC, embedded MCU board with commonly used UART (ELM-A) or USB (ELM-B) interfaces. ELM is mainly intended for the ISM (Industrial, Scientific, and Medical) frequency bands at 862-932MHz. The module integrated many RF functions and PA to make the maximum output power up to +20dBm and signal coverage can reach up to 5km. Users can control the external device or access external sensor data by UART port. ELM can support very good wireless performance in 2 Km distance with 90% successful transmission rate. Multi-end points can form a broadcast network, with the same frequency and encryption the end points can communicate without pairing in advance. Thus, effectively reduce the effort in deployment and maintenance.
