Analog Devices Inc. MAX32670-xx-ARDZ Development Platforms

Analog Devices Inc. MAX32670-SX-ARDZ and MAX32670-LR-ARDZ Development Platforms feature the MAX32670 high-reliability, ultra-low-power microcontroller based on the Arm® Cortex®-M4 processor. The MAX32670-SX-ARDZ has the SX1261 long-range RF transceiver, while the MAX32670-LR-ARDZ has the LR1110 long-range RF transceiver module. These integrated RF transceivers support a frequency range from 800MHz up to 960MHz. The frequency support makes the devices suitable for high-performance flexible platforms that wirelessly transmit encrypted data at long range, enabling a wide range of IoT applications using Analog Devices sensing solutions. MAX32670-LR-ARDZ also utilizes Semtech’s Long Range Cloud™ Geolocation capabilities to significantly reduce power consumption by determining asset location in a cloud-based solver.

Due to low power consumption, these modules are ideal for devices running on small-sized batteries. The onboard MAX32670 Arm Cortex-M4 32-bit microcontroller provides the platform with the capability to run entire RF stacks and user applications.
