Ezurio Lyra Series BLUETOOTH® 5.3 Modules

Ezurio Lyra Series BLUETOOTH^® 5.3 Modules, based on the Silicon Labs EFR32BG22 SoC, provide a turnkey solution for adding Bluetooth wireless connectivity to any application. The Lyra Series Modules feature low-power operation, making them ideal for battery-powered devices. These devices also come with fully upgradeable, robust software stacks, worldwide regulatory certifications, advanced development and debugging tools, and support that will minimize and simplify the engineering and development process, helping to accelerate time-to-market.

The Ezurio Lyra Series Bluetooth 5.3 Modules are available in compact PCB (LYRA P) and SiP (LYRA S) form factors. Both devices feature an integrated antenna. The LYRA S SiP Module also supports an external antenna via trace pin.
