A few weeks ago I received an email from LT that was showcasing the LTC2946, a power monitoring IC that communicates using I2C. I was intrigued and ordered a couple, part number LTC2946CMS#PBF. This is the MSOP-16 package and I would need a breakout board so that I could play around with this chip on a breadboard and explore all of its functions. I looked at my normal sources for electronic goodies; Adafruit and Sparkfun had MSOP break out boards but they were all low pin count. I was able to find another source for a MSOP-16 breakout board but at ~$7 a piece plus shipping I knew I could have my own made much cheaper. On to KICAD.
