The limited edition Propeller 2 Eval Board Rev C is designed for experimentation and characterization of the Propeller 2 multicore microcontroller engineering samples (Rev C silicon, approved for production).

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.

What's New for Rev C?

Production-approved P2X8C4M64P Engineering Sample Rev C silicon
P0–P15 and P32–P47 are trace-length matched for high-speed data experiments (such as HyperRAM).
BOD (Brown Out Detection) is removed from the dip switch and instead, Propeller RESn is permanently connected to the 1.8V regulator PG (Power Good) signal, which will hold the P2 in reset if the regulator voltage drops below ~1.5V.
USB RES is on the dip switch, which enables the user to disconnect the USB reset (DTR) signal from the Propeller RESn pin.
The 5V pin which was next to P30 has been removed, and that pin is now unconnected.
The 5V pin which was next to P62 has been replaced with a RESET input to the Propeller RESn.
The unpopulated DTR/RESn pads which RevB had (near the SD socket) have been removed.
Improvements to the USB power circuit to improve protection from edge-case faults.
WX WiFi Compatible —The P56–P63 edge header works with the Parallax SIP WiFi module for wireless programming.
