Choosing a prototype board
Our protoboards come in several sizes to fit chips with different pin width and spacing (pitch). Here's how you can find the pitch of your chip and get the right protoboard:
- Find the datasheet for your chip
- Look for a 'package info' or 'recommended landing pattern' section. This section will have a diagram of the chip and a list of measurements
- Look for the pitch measurement, this is the distance between the center of two pins. This is often labeled 'e' or 'E', as in our examples
- Pitch may be given in mm, mils, or inches. See the table below
