Laird-Connectivity's-Enhanced-Lyra-5.3-Series-Is-Available-At-Symmetry-Electronics

Laird Connectivity has leveraged their over 40 years of expertise in wireless modules, internal antennas, IoT devices, design services, and RF and EMC testing to launch their advanced Bluetooth 5.3 Lyra Series. Integrating Silicon Labs’ EFR32BG22 SoC, the Lyra Series combines SiLabs’ hardware, software, and tools with Laird Connectivity’s value-added application software, services, certification, and support capabilities. This seamless collaboration provides customers with multiple software development options suited to their resources and skillsets in Bluetooth LE-enabled product development.

The Lyra Series includes the Lyra P, small form factor PCB module with an integrated antenna and the Lyra S, ultra-compact SiP module with an integrated antenna and support for multiple additional pre-certified antennas. The feature-rich Lyra Series is suitable for battery-powered IoT devices and was developed to drive down total cost of ownership, minimize design complexity and risk, and accelerate time to market.

Lyra Series Development Kits

The Lyra Series (Lyra P and Lyra S) development kits offer everything needed to start Bluetooth LE development. Integrating a Segger J-Link debugger, USB Micro B for power, HW switch for FW options, buttons and LEDS, and Mini Simplicity (on base), Mikrobus, and Qwik connector options, the Lyra Series dev kits include everything needed for rapid device evaluation. The Lyra S DVK is mounted with an MHF4 connector to root to an external antenna.

Lyra Series Comprehensive Development Services

Laird Connectivity has joined forces with Silicon Labs to offer a secure, feature-rich solution for Bluetooth LE product development. Choose between the Lyra P, small form factor PCB module with an integrated antenna or Lyra S, ultra-compact SiP module with an integrated antenna and external antenna capabilities. Offering three firmware operations (AT Command Set, Wireless Xpress, and C Code), the Lyra Series offers a flexible development option for diverse applications like professional lighting, asset tags and beacons, secure medical peripherals, and industrial IoT (IIoT) sensors. Combine the Lyra Series evaluation boards with Laird Connectivity’s value-added technical support and certification services to benefit from reduced costs, simplified development, and accelerated time to market.
