Propteus rev. 2.0

top shot of assembled Propteus

Propteus is a flexible through-hole Propeller development board with a large prototyping area – the latest addition to the “Mikronauts Modular System”.

It can be minimally populated with the power supply section, Propeller and EEPROM (available as “Propteus Base Kit”) or it can be built up into a full development board with micro SD card reader, VGA output, TV output, stereo line level audio, PS/2 keyboard/mouse … or anything in between. Of course, you can add your own custom circuits in the large advanced prototyping area.

Propteus was designed to easily run SphinxOS – if you use the TV output, you will still have 16 Propeller pins free for your own experiments.

  • PropPlug / SerPlug compatible HCOMM connector
  • four pin I2C expansion connector
  • power LED
  • large high density advanced prototyping area
  • unique zig-zag power bus for prototyping area
  • optional micro SD socket
  • optional TV output
  • optional VGA output

(As usual, Sapieha made a beautiful PCB layout)

The VGA, PS/2 and TV options are on the same pins as on the Parallax Demo Board so most demos and Obex objects will “just work” if you run Propteus at 80MHz!
