Propeller ASC schematic:
* Revision "f" PCB - [[file:pasc-f.pdf]]

The Propeller ASC is an Arduino Shield Compatible prototyping system designed to use existing Arduino add-on boards with the Propeller's SPIN language or Propeller Assembly. To stay up to date with the development of this product, please subscribe to [http://forums.parallax.com/showthread.php?t=124288 this thread] at the Parallax forums.

===Features===
* mini-USB interface using FT232RL.
* MCP3208 12-bit analog to digital converter. [http://ww1.microchip.com/downloads/en/DeviceDoc/21298e.pdf Data sheet]
* 3.3v AUX port for extra digital I/O or TV/keyboard/mouse or RGB using only a few resistors.
* Fourteen Arduino compatible, current protected 3.3v digital I/O pins.
* PWM, I2C, SPI, UART and more, in any combination on any pin.
* A 32K EEPROM for storage of your programs. (64K on ASC+ • 32K for program • 32K for data)
* 3.3v and 5v voltage regulators.
* Can be powered from the USB port or with 6-12v 2.1mm power jack.
* Power from USB is protected by a 500mA polyfuse.

===Software===
* Download the free Propeller software from the Parallax website at http://www.parallax.com
* [http://www.fnarfbargle.com/bst.html Brad's Spin Tool] is a little more advanced option that will also run on Linux.
* For professional development and debugging in the SPIN language, [http://hannoware.com/viewport/ ViewPort] is hard to beat
* For drag-and-drop programming, the 12-Blocks GUI is a must-have.
* A large list of Arduino shields can be found at http://shieldlist.org.
* If C is your preference, try the free [http://sourceforge.net/projects/catalina-c/ Catalina C] or [http://code.google.com/p/propgcc/ PropGCC]
* For a nice "UNIX like" interface check out [http://forums.parallax.com/showthread.php?123795-spinix spinix]

== Current Limiting & 5 volt compatibility ==
[[file:jumper.png|link=|Jumper Schematic]]

The Propeller chip is a 3.3 volt device, so the ASC uses a series of 2.2K resistors to protect pins P0 through P13. Since some Arduino shields are designed to use 3.3 volts, there are bypass jumpers on the back of the ASC to take the current limiting resistors out of the circuit. These resistors will not interfere with low speed signals such as buttons or switches. However, high speed signals like those of an SPI or I<sup>2</sup>C device might be attenuated too much for the Propeller to detect. In these cases adding a blob of solder across the appropriate jumper on the back will alleviate this problem.

== Add-on cards ==
[[file:asc_aux.png|link=|AUX header pinout]]

These add-on cards make use of the Propeller ASCs AUX header on the right side of the board. This header is integrated with a standard Arduino "ICSP" (or "SPI") header above it, and pins 6 and 7 from the ADC chip below. '''WARNING: Pins P16 through P23 are not protected! Do not apply above 3.3 volts to these pins!'''
