Find Designs, Fast

About Reference Design Library

Instead of searching many manufacturer sites or calling on companies to find and compare designs, now you can search for designs based on the circuit’s performance using Digi-Key’s Reference Design Library.

The Reference Design Library was created in order to:

  • Save Engineers time
  • Deliver ideas, fast
  • Sift through designs based on performance
  • Provide designs conveniently accompanied by their schematics

Visit often as new designs are being added weekly and improvements will be made based on your constructive feedback.

Particle Xenon: nRF52840 with Mesh Networking and Bluetooth

Manufacturer: Particle Industries, Inc.

The Xenon is a low cost mesh-enabled development board that can act as either an endpoint or repeater within a Particle Mesh network. The Xenon is mesh only and designed to function as the endpoint of your IoT network. It is based on the Nordic nRF52840 and has built-in battery charging circuitry so it’s easy to connect a Li-Po and deploy your local network in minutes.

STEVAL-ILL079V1: 500mA @ 30V Max, 15 ~ 30V in, Inverting Buck Boost

Manufacturer: STMicroelectronics

The STEVAL-ILL079V1 product evaluation board is based on LED6000 monolithic current source for high power LED driving. Thanks to the wide device input voltage range, alternative topologies like inverting buck-boost can be effectively implemented. Eight white LED (30 V max.) can be powered by 0.5 A programmed current. Digital dimming is implemented by driving the dedicated DIM pin and the necessary level shifting is achieved with inexpensive external circuitry.
