The SAM R34 is a family of ultra-low power microcontrollers combined with a UHF transceiver communication interface. It uses a 32bit ARM® Cortex® -M0+ processor and offers up to 256KB of Flash and 40KB of SRAM, including an area of battery backed-up SRAM. The UHF transceiver supports LoRa® and FSK modulation. LoRa technology is a spread spectrum protocol optimized for low data-rate, ultra-long range signaling. It is ideal for battery-powered remote sensors and controls.
