Particle Monitor One, Manual

Page: 21 / 45

Expansion card interface
Expansion card size: 50mm x 90mm (approximately 2" x 3.5")
Connectors: 24-pin 0.1" headers (two, one on each long side)
Male header pins on the bottom of expansion card
Attachment: 4 screws to standoffs (M3 screw recommended)
Pre-built expansion cards will be available, including the Prototype Card. You can also design and
fabricate your own.
If you are building your own card, you can start with the design for the I/O card or prototype card.
The Eagle CAD schematic and board layout files can be found in
Monitor One Github repository .
