Product Details

The MAX32670-SX-ARDZ base board features the MAX32670 high-reliability, ultralow power microcontroller based on Arm Cortex®-M4 processor, and the SX1261 long range RF transceiver. The integrated RF transceiver supports a frequency range from 800 MHz up to 960 MHz, making it suitable for high-performance flexible platforms that wirelessly transmit encrypted data at long range; enabling a wide range of IoT applications using ADI sensing solutions.

Due to its low power consumption, this module is ideal for devices running on small-sized batteries. The on-board MAX32670 Arm Cortex®-M4 32-bit microcontroller provides the platform with complete capability to run entire RF stacks and user applications.
