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.

3657: ATSAMD09 seesaw SAM D ARM® Cortex®-M0+ MCU

Manufacturer: Adafruit Industries LLC

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities.

ADP1071-1EVALZ: 5.5 @ 500mA, 24V @ 400mA, & -15V @ 200mA, 18 ~ 32V in

Manufacturer: Analog Devices Inc.

The ADP1071-1EVALZ evaluation board is set up to act as an isolated power supply solution that incorporates three output voltages (+5.5 V, +24 V, and −15 V) at a total rated power of 15 W. The evaluation board also provides 5 kV isolation in compact form factor, making it suitable for industrial applications, which usually have a variety of voltage rails.
