0.100″ proto boards are readily available and great for prototyping with 1980’s DIP thru-hole technology. Trying to use them with 1990s and newer surface mount devices is like picking your teeth with a log however. 0.050″ pitch vias line up perfectly with SOIC ICs, SOT-23s and 0603s passives but for whatever reason proto boards with 0.050″ pitch don’t really exist. Black Mesa Labs aims to change that. BML is proud to introduce a family of 0.050″ pitch proto boards for interfacing with Arduino, RaspPi and FPGA boards. All boards designs are available for free and may be purchased from OSH-Park directly or optionally downloaded as Gerbers and CopperConnection layout files from my public Dropbox here. If you don’t want the convenience ( and free shipping ) of ordering directly from OSH-Park, the Gerbers may be uploaded to most PCB fabs ( for example, ITEAD in China ).
P.S. – While you air wire your circuit together, don’t forget to use some Copper tape to add extra ground returns and signal shields.
These FPGA single PMOD boards come in 1″, 2″ and 3″ lengths ( 2.5cm, 5cm, 7.5cm ). They provide both a GND and 3.3V perimeter. They have a FPGA PMOD connector footprint on the left, but may be used standalone of course without an FPGA board.

These FPGA dual-PMOD boards also come in 1″, 2″ and 3″ lengths ( 2.5cm, 5cm, 7.5cm ). They provide both a GND and 3.3V perimeter.

The Arduino UNO board should mate with any board with a UNO footprint. It has a GND, 3V and 5V perimeter ring around the 0.050″ grid. There is also a 2×15 0.100″ grid on the left for external interfacing ( or large components ). A FTDI 1×6 0.100″ connector is available for (optionally) connecting to the Arduino RX and TX serial lines.

The Arduino ProMini shield is extremely multipurpose as it can be used to interface small SMT devices on a 0.050″ grid to a standard DIP 0.600″ grid ( breadboards ). PCB design uses castellated 0.100″ vias on the perimeter allowing this board to be soldered directly to the back of a Pro-Mini or any 0.100″ proto board without requiring any tall headers. Kapton tape should be placed between PCBs to prevent shorting. If you have just a few surface mount components you want to add to a bigger 0.100″ proto board design – this is the board for you. Cheap too.

If you don’t already know about the Arduino Pro-Mini – it’s an awesome deal for $10.
The Pi Zero shield may be used with any Pi with a 2×20 0.100″ header. It has a GND, 5V and 3V perimeter ring around the 0.050″ grid. 2×7 0.100″ grids are available on both the left and right sides of the board.

Latest is this 1″ x 1.5″ generic 50mil + 100mil that can optionally be snapped in half. Only $7 for Qty-3 from OSH-Park here.
And finally, BML is working on a family of SMT to 0.050″ “sleds”. Castellated PCBs for breaking out really small SMT stuff to the larger 0.050″ grid.
Misc SOIC-16 to 0.050″ castellated for like $1.
Misc SOIC-8 / SOT-23-8 to 0.050″ castellated for like $1.
