[TriEmbed] Lowest learning curve to design a board?

[Brian]

Caps can help with ESD, but I'd suggest using purpose-made TVS 
(Transient Voltage Suppression) devices, which are usually more like 
diodes than capacitors.

Selecting appropriate TVS diodes is a whole deep-dive itself that I 
readily admit I don't fully understand...I generally go with whatever 
application notes suggest.  A basic rule of thumb is to pick one with a 
breakdown voltage slightly higher than the positive rail of your power 
supply, but lower than the maximum input voltages of the components 
involved.  That maximum is often Vdd + 0.5V, but read your datasheets.
