ESD protection for micro receiving off board signal

A TVS diode may not have the accuracy necessary to protect the input.
A small resistance (e.g 1kΩ) in series with the input, along with small Schottky diodes, one from the micro's input (anode) to the micro's V+, and one from the micro's input (cathode) to ground should work.
That should protect against both plus and minus transient voltages.
