About Propeller Platform

bullet

This is another in a series of Propeller Platform boards that started with the original by Jon Williams, picked up and made popular by Nick at GadgetGangster.com and also available as the DNA board by Martin Hodge at mghdesigns.com

Design Notes:

bullet

Power can be provided by either by USB from computer or powered USB hub or a 6..9 VDC power supply connected to the jack provided.

bullet

An additional 2-pin header (J4) is provided to provide power from wires, if desired.

bullet

The microphone position has been moved from the original position shown in the photo above to reduce noise.

bullet

The second eeprom header can also be used for other I2C devices, such as the 3AD accelerometer.

Hardware for Expansion

bullet

Headers (You can use headers to attach shields above or even below your PPE)

bullet

Usually we put female headers on the outer rows on both sides and male pins on the shield

bullet

Here are Digikey part numbers for what we use:

bullet
16-position female header, single row:  929974E-01-16-ND
bullet
Note:  You can just use wire cutters to cut one up to make the 4-pin header (you do lose one position this way).
bullet
Regular length male pins, 36-position, single row:  609-3465-ND
bullet
Longer length male pins, 36-position, single row:  S1211E-36-ND
bullet
The longer length might be better for the VGA Graphics Shield to give clearance.
