NOTE: One Rev B board per customer. Quantity limited to stock on hand; orders may not be shipped the same day as placed to accommodate order history review. No warranty, exchanges, or returns are available for this board.
The limited edition Propeller 2 ES Eval Board Rev B is designed for experimentation and characterization of the Propeller 2 multicore microcontroller engineering samples (2nd samples, Rev B silicon).
Multiple ground points, power supplies, and power enable & breakout headers are included for simpler testing and interfacing with standard test equipment. The PCB is organized to keep each subsystem clearly defined in groups, and spaced well apart, making room for test probes to be attached.
The eight I/O Pin Breakout Edge Headers accommodate the 2x6 pass-through headers on eight different accessory add-ons, for experimenting with HyperBus memory, audio, video, and more. See the Propeller 2 product family page for options.
The P2-ES Eval Rev B needs PNUT v33k or higher for programming, available from propeller.parallax.com. See the Additional Resources tab below for links to the P2-ES Eval Board product guide, the Propeller 2 Datasheet, Propeller 2 Instruction Set, and a GitHub repository for community-sourced example code.
