PARTS LIBRARY: 85×56 credit card sized standard PCB template

There’s now a 85mm x 56mm credit card sized standard PCB template in our Eagle parts library. Thanks to TonyD for the suggestion. These standard board templates to take the hassle out of pretty edges and consistent mounting hole placement. We’ve been using them for a few months, and quietly lasered a few test cases that […]

PARTS LIBRARY: 2×07 0.1″ pitch shrouded pin header

We added a 2×07 0.1″ pitch shrouded pin header in our Eagle parts library. We extended the shrouded header footprint, as the previous version was slightly smaller than the actual part. We also updated the 2×5 and 2×6 headers. This header could possibly replace the 12 pin header on Bus Pirate v4. The v4 2×6 […]

PARTS LIBRARY: Bourns 3306F trimmer resistor

After a few problems with standard Eagle trimmer footprints, we added the Bourns 3306F trimmer to our Eagle parts library. It seems to be a pretty common-ground footprint. We used a larger than recommended pin-hole diameter so it will work with other common trimmers too. We use trimmers as adjustable voltage dividers, such as for […]

EAGLE PART: Incremental encoder with switch

Rotary encoders are an easy way to add user input to a project, especially for stuff like menu selections. Turn the knob left and right, push down to select an option. We’ve used encoders in several recent projects. One problem we had was that the knob overlapped another part. After a quick measurement with digital […]
