Propeller Breadboard
A Basic P8X32A Microcontroller Board for Prototyping
This project is a small board for prototyping circuits using the Parallax P8X32A (Propeller) microcontroller. All I/O pins from the processor are brought out to a single row of pins spaced at 0.1" intervals along the edge of the board. The circuit board also has two pins providing regulated +5V and Gnd to power the breadboard rail. A second regulator onboard provides the +3.3V for the P8X32A and the 24LC512 EEPROM.
Hardware
The schematic and layout for the Propeller Breadboard is below. It is a 'bare bones' circuit to support the Parallax Propeller. Input power is 7.5-10VDC, provided through a standard 2.1mm power jack. The voltage is regulated to +5V via a LM7805 regulator. The +5V is provided to pins to power the breadboard rail and to the input of the LM2950ACZ which provides the regulated 3.3V to power the microcontroller and EEPROM. Programming of the board is done via a Prop Plug or similar logic-level serial interface.
