P2 Edge Mini Breakout Board (#64019)

The P2 Edge Mini Breakout Board provides a compact interface to the P2 Edge Module for

experimenting and developing with the Propeller 2 microcontroller.

The board accepts the P2 Edge Module (#P2-EC) and includes a supply voltage DC Jack socket,

Parallax Prop Plug (#32201) programming header, and reset button. Forty of the P2 Edge Smart

I/O pins are available at five 0.1” pin header sockets, compatible with both single and dual

header Propeller 2 accessories. Four accessory headers are arranged to accept single or dual P2

accessory boards, and the fifth single header breaks out the programming pins and is

compatible with wireless programming using the P2 WX Adapter (#64007) with Parallax WX

ESP8266 SIP module (#32420S).

Smart I/O pins P0–P31 and P56–P63 are available at pin headers. Pins P32–P55 may be

accessed by adding jumper wires on the bottom side of the PCB to the mini prototyping

sections. There are two 0.1” pitch 4x5 matrix prototyping sections on the board, positioned on

either side of the edge connector.

Features

● Vertical socket for the Parallax P2 Edge Module (#P2-EC)

● Solder-free prototyping, header sockets for power, programming and I/O

● Center-positive 2.1 mm barrel jack for external 5 VDC power supply

● Convenient reset button

● 40 Smart I/O pins brought out to 0.1” 2x6 way P2 accessory headers

● Dedicated Parallax Prop Plug (#32201) header, for system programming and debugging

Feature Descriptions Read the full explanation of each labeled feature on the pages that follow this diagram. 1. Parallax P2 Edge Module Socket The P2 Edge Module socket is a 0.05 in (1.27 mm) pitch, 80-way vertical socket. Refer to Edge Connector Pin Assignments in the P2 Edge Module product guide for full details. The P2 Edge Module must be inserted with the component side facing the RESET Button. There are silk-screen text markings beside the socket to indicate the positions of P0 and P38.

3. Prop Plug Programming Header The P2 Edge Module is programmed by the Parallax Prop Plug programming tool (#32201). To accommodate the Prop Plug, there is a dedicated 4-pin programming and debugging header. The pins are marked ▽ △ RES VSS, and correspond to the pin labelling on the Prop Plug adapter. Connect the Prop Plug to your computer with a suitable USB cable. Then, insert the Prop Plug onto the header pins with the Prop Plug components facing upward.

7. I/O Pin Breakout Edge Headers (without 5V output) There are two edge headers that do not have 5V routed to them, one for P24-–P31, and one for P56–P63. The P24–P31 header is marked with a white silk square for the pin beside the Vxx pin. This unlabelled pin is unconnected, but may be used for connecting a user signal or voltage to a user accessory board or prototype board. The P56–P63 header is marked with the RES pin label beside the V56 pin.
