The Raven Transceiver module consists of an 802.15.4 RF transceiver paired with a microcontroller specifically designed for the Thread protocol. The Raven module is an IEEE 802.15.4 standard radio paired with an ARM Cortex-M4 microcontroller. The IEEE 802.15.4 standard specifies the radio PHY and MAC layers, the low-level physical control and operation of the radio. This standard has become popular due to its support for low-power and high-reliability systems. It also provides a foundation for standardized wireless communication between products from different manufacturers.
The module has dual crystals provide highly accurate wake-up timing for sleepy end devices. It provides a link budget of -110 dBm and has sufficient memory (512k flash) to run Thread and applications stacks. The Module is available in multiple options with an on-board antenna, PCB antenna and u.FL connector for an external antenna.
