NOTE: Sold out. The next build will be Revision C,  sold under stock code 64000. It will use P2 Rev C engineering samples, which are approved for future production silicon.

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. No warranty, returns, or exchanges for this item!)  Sign up for our P2 Newsletter here.

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 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.
