About the Particle somduino PCB

Particle somduino is an open source PCB design by epietrowicz, published on GitHub. It is a 2-layer board measuring 68.6 × 53.3 mm, with 26 components from 18 distinct parts.

Other key parts include the BSoM404 and PM-BAT. By type, the board carries 10 resistors, 8 connectors, 3 switches, 2 ICs and 2 diodes.

It belongs with the dev boards & breakouts and power & battery designs in this gallery.

From the project

The cost of the example design is $54.88 for 5 mostly assembled boards. All that remains is a Particle SoM and power module. It is worth noting that I did not choose to upgrade from the “economic assembly” for the threaded standoff and plan to hand assemble that component saving
