SAM R30 integrates an ultra-low-power MCU and a sub-GHZ radio in a tiny 12.7 × 11 mm package to enable longer battery life in space-constrained designs.
The module is based on the Microchip SAMR30E18A SiP with a 32-bit Arm Cortex-M0+ core and up to 256 Kbyte flash and 40 Kbyte RAM. The module has been developed for use in unlicensed sub-1GHz frequency bands worldwide. It delivers receive (RX) sensitivity up to -105 dBm and transmit (TX) output power up to +8.7 dBm.
The module has double the connectivity range than similarly powered 2.4GHz modules, and also offers better penetration through walls and floors. An ultra-low-power sleep mode of below 800 nA makes the SAM R30 module ideal for IoT sensor applications. Developers can implement propriety point-to-point, star, or self-healing mesh networks using Microchip’s MiWi protocol stack.
Mouser has also added the SAM R30M Xplained Pro Evaluation Kit. The kit includes an onboard embedded debugger, QTouch button, two Xplained Pro extension headers, and embedded current measurement circuitry. It has a chip antenna and an SMA connector for an external antenna, a digital temperature sensor, and USB-UART/I2C convertor. The board is supported by the Atmel Studio IDE.
The module and the evaluation kit are certified with the Federal Communications Commission (FCC), Industry Canada (IC), and Radio Equipment Directive (RED).
