EYE ON NPI – Twin Industries Combination Protoboards #EYEonNPI #digikey @DigiKey @twin_ind


This week’s EYE ON NPI is a one-two-triple punch of awesome: its a combination prototyping breadboard kit from Twin Industries (https://www.digikey.com/en/product-highlight/t/twin-industries/combination-protoboards). Offering the best of three worlds in one: it has a gridded prototyping development area, a ‘perma-proto’ style 5-row DIP area, and a separate chunk of solderless breadboarding material for quick connections.


There are three versions of these combo-boards, each one is made of green-masked double-sided FR4 with gold/ENIG coating to reduce oxidation. The solderless breadboard chunk is bolted in place, but please note it does need to be soldered if you plan to use it, the bolt is not going to make electrical connectivity between boards.

  • Solderless, 5 holes per pad
  • 0.1″ x 0.1″ grid of holes
  • Plated holes: 0.037” diameter
  • Lead-free PCB with gold plating: 0.062” thick
  • 3 mm screw/nut is included to secure the module to board (additional soldering required)



You can pick up Twin Industries combination protoboards over at Digi-Key today! (https://www.digikey.com/en/product-highlight/t/twin-industries/combination-protoboards) We’re partial to OB1-LF (https://www.digikey.com/en/products/detail/twin-industries/OB1-LF/7423017) ourselves, but all three look good to us. They are in stock for immediate shipment, buy today and you can be prototyping in style by tomorrow morning.
