The Lyra P from Laird Connectivity is a Bluetooth 5.3 Module that is designed for battery-powered IoT applications. It provides a Tx power of +8 dBm and supports AoA, AoD, and Bluetooth LE Mesh features. The module is based on Silicon Labs EFR32BG22 SoC and has integrated Cortex-M33 core, 512 kB flash, and 32 kB RAM. It uses intelligent power schemes and deep sleep mode to reduce power consumption and provide a long-performing IoT solution on battery. This module requires a DC supply of 1.8-3.8 V, consumes 4.8 mA of current in Tx mode and 4.3 mA of current in Rx mode.

The Lyra P can be controlled via UART, I2C, SPI, 12/16-bit ADC, GPIO, PWM, PDM, Watchdog, and PRS interfaces. It has security features like Secure Boot, ARM Trust zone, and hardware cryptographic acceleration. The module is available in a cut/tape or tape/reel package that measures 12.9 x 15 x 2.2 mm with an integrated antenna.
