2mm spacing stripboard/prototype boards available?

[splin]

A lot of modules, such as the dirt-cheap ESP2866 based WI-FI modules I just bought have 2mm spacing. Can you get stripboard or prototype boards with the same spacing to make it a bit easier to prototype?

Or perhaps 2mm to .1" adapter boards suitable for a range of modules with differing widths and number of pins (within reason!)

Does anyone know why they have those 'castellated' edges for the connections rather than the plated through holes that you usually get on Arduino type modules with .1" spacing? Is it to minimise the size?

TIA

Have you tried google search? It gives hits like this one

The holes are cut so you can solder it directly to a board, SMT like.

Doh thanks! In my defence, being a  cheapskate I was searching unsucessfully on Ebay. I did try searching the distributers but it can be very difficult to find some things navigating through their websites.

Still, those 2mm pitch 'plugboards' are very expensive at $14 for a 4" x 6" board - especially when you add on shipping and the DHL rippoff handling charges.

Consider just whipping up your own!

Elecrow only charges $15 for 10 pcs of 10x10cm boards (green soldermask only). They're decent quality too.

Plus you can add a section for 2.54mm parts, SMD parts, what have you.

Seeed studio has some too - I have bought some by mistake and then was left scratching my head why the normal 0.1" pin headers don't fit!
