Right angle board to board connectors

Hey guys,

I am trying to connect two custom PCB boards in a right angle (perpendicular to each other) and dont know of the smartest way to do it. I was initially thinking of a board edge connector on one PCB and a socket on the other (kind of like a RAM chip) but the connectors seem pretty expensive. Anyone have any advice on sourcing the proper parts to create a board to board connection? I need 12 pins and would like the cheapest way of making it happen.

Thank you!

Edge connectors are available in various shapes, the smaller the expensive.

A search for (Mini) Module Connectors reveals many (also cheap) connectors.

connectors are often the most expensive part of a project.

Pin headers?

A right angle pin strip and a matching straight socket doesn't empty your bank account.

right angle 1x40 ale header $0.99
1x5 female header $0.44

total $1.43

verical :
ATMEL ATMEGA328 : $1.77

won't break the bank, but the most expensive parts of a project are typically the enclosure, the PCB and then the connectors, with the connectors often being the mos expensive part.

I have a board that has removable screw terminals, lift off type. cost over 50 cents per conductor.
has 20 conductors.
