PA2 2011-05-20 Added errata information (silk screen print) in section 3.4.1. A 2012-01-18 Added clarification that pin names refer to LPC1114 and LPC1343 (and not to for example LPC1769 and LPC1227).
LPCXpresso Prototype Board - User’s Guide Page 5 2 Introduction Thank you for buying Embedded Artists’ LPCXpresso Prototype Board, designed for the LPCXpresso Board (for many different target boards in the LPC1xxx family) and the mbed module from NXP’s. This document is a User’s Guide that describes the LPCXpresso Prototype Board hardware design. The general focus will be for the LPCXpresso boards but differences for the mbed module will be noted. 2.

LPCXpresso Prototype Board - User’s Guide Page 7 3 Getting Started This chapter contains information about how to get acquainted with the LPCXpresso Prototype Board. Please read this section first before you start using the board - it will be worthwhile! 3.1 LPCXpresso The main source of information about the LPCXpresso LPC1xxx boards as well as the LPCXpresso Debugger/IDE is http://www.nxp.com/lpcxpresso.
LPCXpresso Prototype Board - User’s Guide Page 8 Figure 3 – LPCXpresso Board with Pin Lists Facing Down The headers shall be soldered onto the front side of the LPCXpresso Prototype Board, as seen in Figure 4. Figure 4 – LPCXpresso Prototype Board with Headers Facing Up Figure 5 shows the LPCXpresso Board mounted in the LPCXpresso Prototype Board.

LPCXpresso Prototype Board - User’s Guide 3.3 Page 10 Board Powering The LPCXpresso Prototype Board distributes voltages according to Figure 6. The red rectangles illustrate the holes where GND-potential is available. All the areas are connected. The green rectangles illustrate where +3.3V-potential is available. All the areas are connected. The pcb silk screen also indicates where GND and +3.3V is available. Figure 6 – Board Powering Note that the “+3.3V” potential is about +3.
LPCXpresso Prototype Board - User’s Guide 3.4 Page 11 Main Components This section describes the different areas of the LPCXpresso Prototype Board. 3.4.1 LPCXpresso / mbed Signals All signals on the LPCXpresso Board / mbed module are accessed easily just right next to the headers (marked with green rectangles in Figure 7). There is also silk screen text on the pcb listing the signal names.
LPCXpresso Prototype Board - User’s Guide Page 12 There are two errors in the silk screen related to the mbed pinning (in-between the headers). Rows shall be switched, upper: VB lower: nR (reset) Rows shall be switched, upper: UART3-TX/SDA lower: UART3-RX/SCL Figure 8 – LPCXpresso / mbed Signal name errata Also note that all pin names refer to LPC1114/LPC1343 pin naming. The board was originally designed for these processors. The LPC1769 and LPC1227 pin names are completely different.
LPCXpresso Prototype Board - User’s Guide 3.4.2 Page 13 100 mil Pitch Holes A large part of the board is covered with 100mil pitch holes, as indicated in the red area in Figure 9. The holes are 1.09 mm in diameter.
LPCXpresso Prototype Board - User’s Guide 3.4.3 Page 14 50 mil Pitch Holes Figure 10 indicates, in the red area, a prototype area with 50 mil pitch holes. The holes are 0.71 mm in diameter.
LPCXpresso Prototype Board - User’s Guide 3.4.4 Page 15 50 mil Pitch SOIC Components The two red rectangles in Figure 11 indicate prototype areas for 50 mil pitch SOIC components. The SOIC components can have 3.9mm, 5.3mm or 7.5mm (300 mil) wide bodies. Each pad is accessible via a small hole. Figure 11 – 50 mil SOIC Areas In-between the SOIC pads, there are 0603-sides pads for decoupling capacitors. The upper pad on all positions is connected to GND-potential.
LPCXpresso Prototype Board - User’s Guide 3.4.5 Page 16 0.65 mm Pitch SSOP Components The red rectangle in Figure 13 indicates a prototype area for 0.65 mm pitch SSOP components. Each pad is accessible via a small hole. Figure 13 – 0.
