P8X32A QuickStart Board (Rev. B) The QuickStart is an evaluation board for the Propeller. As an open-source reference design the QuickStart board provides basic Propeller circuitry. Developers may use our PCB layout files as their own to speed their project towards completion. As a project board the QuickStart is fully expandable and provides unimpeded access to all I/O pins through an expansion header but includes some button inputs and LEDs to demonstrate programming. With USB power and a selection of QuickStart Project examples it's also the fastest way to get up and running. Note: A USB-A to Mini-B cable is required, not included. Examples at Parallax Semiconductor:QuickStart 1: Comparison of Programming Tools QuickStart 2: Propeller Programming First Steps QuickStart 3: Introduction to Spin Objects QuickStart 4: Common Methods Found in Objects QuickStart 5: Multiple Cogs QuickStart 6: Using the Parallax Serial TerminalFeatures: Open hardware reference design through our Altium and DipTrace PCB layout files (more export options may be possible) Bus-powered USB coupled with 3.3V regulator for 500 mA 5 MHz crystal on board may be disabled by removing SMT jumper, allowing replacement with external through-hole crystal 64KB EEPROM (32K for P8X32A program, 32K for general-purpose use) External brownout reset may be installed by removing SMT jumper (8) blue LEDs on P16-P23 (8) resistive touch-buttons on P0-P7 Pads for sigma-delta A/D circuitry (two resistors and two capacitors, both 0603) for using the Sigma-Delta A/D AppNote Expansion header provides access to Vss, Vdd, 32 I/O pins (28 for any use, 2 are IA2C bus, and two are optional Tx/Rx if connected to USB power) Measures 2" x 3" (5.1 cm x 7.6 cm) Specifications Power Requirements: 3.3 or 4 to 9 VDC, up to 500 mA Communication Interface: USB, 3.3 V serial, IA2C Operating temperature: -40 to 185 F (-40 to 85 C) Dimensions: 2.0 x 3.0 x 0.36 in (5.0 x 7.6 x 0.84 cm) Downloads & Resources:Visit Parallax Semiconductor for the most recent downloads and support files.
