IEEE 802.15.4-compliant module is only 12.7x11mm
The SAM R30 module is what Microchip claims to be the industry’s smallest IEEE 802.15.4-compliant module, combining an ultra-low-power microcontroller (MCU) with a sub-GHz radio.

Measuring just 12.7x11mm, about half the size of the next smallest module on the market, the SAM R30 module meets the needs of space-conscious designs such as home automation sensors and controls. Based on IEEE 802.15.4, the device supports proprietary networks that can be easily customized and configured. A key advantage of an IEEE 802.15.4-based network is that member devices can sleep for extended periods of time and remain part of the network. The SAM R30 module features ultra-low-power sleep modes, with wake from General-Purpose Input/Output (GPIO) or its built-in Real-Time Clock (RTC) while consuming approximately 800nA. Devices can sleep for years, only waking as needed to transmit data. The device comes with up to 256KB of Flash and 40KB of RAM, as well as serial data interfaces, USB, and digital and analogue I/O for advanced sensor development. Operating in the sub-GHz RF spectrum, the SAM R30 module delivers two times the connectivity range and better propagation through walls and floors than similarly powered devices using the 2.4 GHz frequency band. This robustness is critical in applications such as leak detection, where the sensor may be buried deep in a remote cabinet, or for pool and spa controllers, which require reliable sub-GHz solutions that can communicate through exterior walls.
