IoT Stamp Module LoRa ISLM3i
OVERVIEW
Prodigy® IoT Stamp Module LoRa LSM3i is a stamp size PCB board developed around the powerful MCU SAM34/ 35 from Microchip® with the RF front end circuit and antenna connector.
The module is optimized for low power applications such as wireless sensors, building and home automation devices, alarms and industrial networks. The LSM3i has built-in 32bit ARM® processor with 256KB of Flash and 40KB of SRAM, including an area of battery backed-up SRAM. The LoRa technology is optimized for long-range communication with minimal line-power demand. Supports maximum transmit power is +17 dBm without an external amplification. The module monitors the input DC battery voltage with its high accuracy ADC circuit.
