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.

CAUTION! The P2 Edge Module power input pads have reverse polarity protection,

but damage could occur from user circuits attached to the IO pins incorrectly, so

care should always be taken to ensure correct orientation.

2. Power Jack

The 2.1 mm center-positive DC power barrel jack socket accepts 5 VDC only. To provide power

we recommend the Parallax USB A to DC-Jack cable (#805-00019) This will allow you to power

the P2 Edge Breadboard from a computer USB port or hub. For higher current applications,

connect the same cable to the Parallax USB Mains Adapter (#750-00001).

CAUTION! Always use a well-regulated power supply and do not exceed 5.5 VDC

input!
