Professional embedded systems engineers, robotics developers, and IoT specialists utilize this board to prototype complex control algorithms, interface with analog sensors, and manage multi-channel digital I/O operations with precision timing. This add-on board solves the critical challenge of extending the P2 evaluation kit's functionality without requiring custom PCB design, allowing rapid prototyping and validation of control systems before production deployment.

Product Overview

The Parallax 64006A P2 Eval Control Add-on Board is engineered as a stackable module that interfaces seamlessly with the Propeller 2 evaluation board through standardized header connections. The board incorporates multiple analog-to-digital conversion channels with 12-bit resolution, supporting simultaneous sampling of multiple sensor inputs at configurable rates up to 1 MSPS per channel. It features dedicated control circuitry for PWM signal generation, enabling precise motor speed control, LED brightness adjustment, and servo positioning with frequency ranges from 1 Hz to 1 MHz, making it ideal for applications requiring deterministic real-time control.

What distinguishes this control add-on is its intelligent integration with the Propeller 2's multi-core architecture, allowing parallel execution of control algorithms across multiple cogs without timing conflicts. The board includes onboard voltage regulation for analog circuits, eliminating ground noise issues common in prototype systems, and provides comprehensive protection against overvoltage and reverse polarity conditions. The modular design philosophy ensures compatibility with existing P2 ecosystem tools and libraries, significantly reducing development time for students, hobbyists, and professional engineers working on control system projects.

How to Use

Begin by physically stacking the Parallax 64006A P2 Eval Control Add-on Board onto your Propeller 2 evaluation board, ensuring all header pins align correctly and the board sits flush against the base platform. Connect your analog sensors to the designated ADC input pins, respecting the 0 to 3.3V input range specification, and attach your output devices such as motors or LEDs to the PWM and digital I/O pins. Launch the Parallax Propeller Tool IDE on your development computer and load the provided example code for the control add-on board, which includes pre-configured ADC sampling routines and PWM generation functions.

Configure the ADC sampling rate and PWM parameters according to your application requirements using the SPIN2 library functions. For motor control applications, set the PWM frequency between 10 kHz and 20 kHz to avoid audible noise while ensuring smooth operation. For analog sensor reading, configure the sampling rate based on your signal bandwidth requirements, typically 10 kHz for temperature sensors and up to 100 kHz for faster dynamic measurements. Compile your code and download it to the Propeller 2 using the USB connection, then monitor real-time sensor values and control outputs through the debug terminal to verify correct operation before deploying your application.

Frequently Asked Questions

What is the maximum sampling rate for the ADC channels on the 64006A board?

The Parallax 64006A P2 Eval Control Add-on Board supports a maximum sampling rate of 1 MSPS (1 million samples per second) per individual ADC channel. When using multiple channels simultaneously, the sampling rate per channel remains at 1 MSPS due to the parallel processing capabilities of the Propeller 2 architecture. This high-speed capability makes the board suitable for audio-frequency signal acquisition and fast transient measurement applications.

Can I use this board with the original Propeller 1 microcontroller?

No, the Parallax 64006A P2 Eval Control Add-on Board is specifically designed for the Propeller 2 evaluation platform and is not compatible with the original Propeller 1 microcontroller. The board utilizes the Propeller 2's enhanced I/O capabilities, faster clock speeds, and multi-core architecture. If you require a control add-on for Propeller 1 systems, contact our technical support team for alternative product recommendations.

What is the input impedance of the ADC channels and can I connect high-impedance sensors directly?

The ADC input impedance is approximately 10 kOhms, which is suitable for most standard sensors with output impedance below 1 kOhm. For high-impedance sensors such as certain pH probes or electrostatic sensors, we recommend using a high-impedance buffer amplifier or voltage follower circuit between the sensor and the ADC input to prevent measurement errors. The onboard analog filtering provides additional protection against noise coupling from high-impedance sources.
