Hello folks, Rochey here. 

Despite a lack of new products recently, development continues when possible. Typical tools we use for development include:

• Cadsoft Eagle 5.11 (Schem and Layout)
• TI Tina (simulation)
• TI Code Composer Studio for MSP430
• Arduino / Energia
• Goldwave (arbritary audio recording and capture)

Anyway, one of the pains of my life are creating new libraries for new components to be used in Cadsoft Eagle. I used to provide a service to make them for other people, but I've found over the years that as my day job has become more time consuming, and a 4 year old in the family, my spare time to development has been reduced.

As a consequence, I started looking for others to make libraries for me. I quick look over at fiverr.com, and in between all the people willing to make graphics for me, I found a supplier who'll make libraries for $5! (https://www.fiverr.com/mochini77) 

• Links to the datasheet
• Full part number (including package suffix) that get's exported to BOM tools easily
• Source of footprint data (e.g. datasheet? Jedec standard?)
• Version control with revision data (e.g. V1.1 - Updated pad width due to manufacturing issues)
• Devices with multiple control methods (I2C/SPI/Hardware) should have different schematic view diagrams

All the data comes together from the Library description, Footprint Description and Device Description to create a view that looks something like this:

 In addition, the library itself has the whole family of devices, and their various control methods as separate devices.
