Learn or teach the basics of electronics, programming, and robotics with this versatile board and our free C-language web tutorials: learn.parallax.com/PropellerAB-WX. The WX version of the Propeller Activity Board expands upon the functionality of the original ( 32910). Theres more current for your projects with independent 1.8 amp 3.3 V and 5 V switching regulators, an upgrade from audio-out-only to a Mini TRRS audio/video (or audio/mic) jack, and selectable wireless socket/USB communication between host computer and the Propeller chip (RF module not included ) Features Built-in 8-core Propeller P8X32A microcontroller, 64 KB EEPROM, and 5 MHz crystal oscillator Solder-free prototyping with breadboard and header sockets for power and I/O Six servo/sensor ports with power-select jumpers Automatically selects between USB and external power sources and provides USB over-current protection 615 V center-positive 2.1 mm barrel jack for external power supplies Convenient reset button and 3-position power switch Onboard mini stereo-audio jack with microphone/video pass-through Built-in microSD card slot for data logging or storing WAV files Wireless Module socket accepts RF modules to simplify remote management Dedicated analog header sockets provide four A/D 12-bit inputs and two buffered variable- resolution D/A outputs Indicator lights show the status of system power, servo power, programming source, DAC output levels, wireless communication activity, and USB communication activity 3.3 V and 5 V switching voltage regulators with independent 1.8 amp outputs Key Specifications Power requirements: 6 to 15 VDC from an external power supply, or 5 V from a USB port Communication: USB mini-B (onboard serial over USB) Dimensions: 4.0 x 3.05 x 0.625 in (10.16 x 7.75 x 1.59 cm) Operating temp range: +32 to +158 F (0 to +70 C) Copyright Parallax Inc. Propeller Activity Board WX ( 32912) v1.0 2/2/2016 Page 1 of 8 Board Features 1) Propeller Multicore Microcontroller System 64 Kilobyte I2C EEPROM for program and data storage 8 core Propeller P8X32A microcontroller 5 MHz crystal oscillator The P8X32A microcontroller has 8 cores, so it can do many different things at the same time. It uses I/O pins P28 and P29 to communicate with the I2C EEPROM for program and data storage. The crystal oscillator connected to the Propeller provides a clock signal for the system. The Propeller can multiply its 5 MHz oscillator signal by up to 16 for a system clock frequency of 80 MHz. 2) Power Jack The 2.1 mm center-positive power jack is one of two power input options. The board accepts 6 to 26 V from this connector, although a maximum of 15 VDC is recommended. This option is useful for robots and other remote applications when the board is not powered from a computers USB port. Parallaxs 7.5 V, 1 A supply ( 750-00009) works well with this board. 3) 1.8 A Voltage Regulators The 5 and 3.3 V switching regulators can deliver up to 1.8 A each, with a 6 to 26 volt input, although a maximum of 15 VDC is recommended. Sockets along the breadboard provide power, from both regulators to circuits built on the breadboard. A jumper along each pair of servo ports optionally Copyright Parallax Inc.
