Hey,

i have an rev B board and the assembly pressure layer on the bottom side don't match the schematic on sheet 4 of 4 (drawn / issued on 03/03/2014).
Have someone the right schematic for me?

The reason for my question is that I need 8 following pins (port bits) on a port (parallel lcd).

Thank you for working

greetings
Andreas

Hi Andreas,
Could you please let us know printing on bottom side?
The latest board has following marking

LPC1549 Xpresso V2 Rev B

Other old boards were never in mass production.

Where did you get this board?

Let me know details and I can help you.

The posted schematic is correct. The problem is with the silkscreen on the pcb itself which incorrectly identifies the LPC1549 port connected to three Xpresso and one Arduino header pins.

We have now posted a new document showing these mis-identifications on the top and bottom silkscreen, and redlined the correct LPC1549 port. This document can be found, along with the schematic, at:

Hey team,

Excuse my long response time...

but the fact is, your Silkscreen correction is correct.

thanks a lot!

and if you could, try to link this file with your lpc15xx download area for other developers.
