AD5933 breakout board

2 layer board of 1.47 x 1.16 inches (37.3 x 29.4 mm)
Uploaded: April 23rd 2018
Shared: April 23rd 2018
Total Price: $8.50

This is a fairly minimal breakout board for the AD5933, with an analog buffer front-end and optional on-board voltage regulator. The schematic is basically the one in the datasheet. Very similar to the Pmod IA. Uses uFL connectors to save space. Easy to drive this from a RPi.
