Mouser launches Microchip SAM R30 Sub-GHz module for ultra-low power WPAN design

November 6, 2019-Mouser Electronics, a global authorized distributor of Electronic components focusing on the introduction of new products, will stock Microchip Technology’s SAMr R30 sub-GHz module from now on. As the industry’s ultra-small IEEE 802.15.4 compatible module, SAM R30 includes an ultra-low-power microcontroller and sub-GHZ radio technology in a 12.7 × 11 mm package. It is suitable for space-constrained designs such as home automation, Wireless networked sensors and control devices in smart cities and industrial applications can extend battery life.

The Microchip SAM R30 module supplied by Mouser Electronics uses Microchip SAMR30E18A system-in-package (SiP), equipped with a 32-bit Arm Cortex -M0+ core, up to 256 KB of flash memory and 40 KB of RAM. The module is designed for sub-1GHz frequency bands that do not require a license—such as 780 MHz (China), 868 MHz (Europe) and 915 MHz (North America), with a receiving (RX) sensitivity of up to -105 dBm and a transmitting (TX) output power up to +8.7 dBm.

Compared with similar devices using the 2.4 GHz frequency band, this module provides twice the connection coverage and better communication capabilities through walls and floors. The SAM R30 module has an ultra-low power sleep mode of less than 800 nA, which is ideal for Internet of Things (IoT) sensor applications that require a long battery life. In addition, developers can also use Microchip’s MiWi™ protocol stack to implement dedicated point-to-point, star or self-healing mesh networks.

Mouser Electronics also stocks the SAM R30M Xplained Pro evaluation kit, which includes an on-board embedded debugger, QTouch buttons, two Xplained Pro expansion heads and embedded current measurement circuits. This development board has a chip antenna and an SMA connector for an external antenna, a digital temperature sensor and a USB-UART/I2C converter. This development board is supported by the Atmel Studio integrated development platform, which provides predefined application examples.

Both the SAM R30 module and the SAM R30M Xplained Pro evaluation kit have passed the Federal Communications Commission (FCC), Industry Canada (IC) and Radio Equipment Directive (RED) certifications, allowing designers to focus on accelerating time to market without having to consider RF testing Certification costs.
