Replacement: None. We are no longer carrying this ProtoBoard in our catalog. This page is for reference only.

We asked ourselves what we would want in a project board. What would an ideal platform for most any given project look like? After putting a laundry list together of 'wants' and 'needs', we created the SparkFun Protoboards. We hope you like it as much as we do.

The marsupial naming convention is what happens when you let Engineers into a Marketing meeting. They looked so happy, we just couldn't tell them no. Diprotodon is the board with USB serial, charging, SMD proto, and PTH proto.

This is a project board specially designed to fit the Sparkfun Enclosures. The board provides the user with 3.3V and 5V regulated rails from a single Lithium Polymer battery. USB serial communication is also on-board with an FTDI FT232 USB chip, with selectable 3.3V or 5V logic. The LiPo cell plugs into the provided JST connector, and charging is available over USB (100mA) or external source (5V, 250mA). Finally, the board has a generous prototyping area that allows a combination of surface mount (2.54mm x 1.27mm, 50mil x 100mil pads) and through-hole components (2.54mm, 100mil spaced holes).

Note: This version has undergone some minor hardware changes including a slight change to the charging circuit and some footprint changes. It still works exactly the same way but the image to the right doesn't reflect the board changes. A new image will be added as soon as possible.
