MIDI_CORE_LPC17 PCB?

28 posts in this topic

I currently want to build the MIDIO 128 v3 (including the lpc17) so i managed to buy a lpxpresso1769. The components are easy to get, but i didnt find any way to get the PCB. Is there any way to buy a PCB online thats already made?
oh, and does anyone know what the dimensions of the PCB are? i just found the datasheet including the Value 100 x 120, but im not sure about the unity.

Greetings,

Kilian

As far as I can see the LPC 17 Core PCB is not available to buy anymore from Smash TV's and Mikes Midibox shops but you can still buy the newer CORE STM32F4 PCB and kit from SmashTV.

Keep in mind you would need to purchase the STM32F407G-DISC1 evaluation board externally.

That would be the easiest way to proceed. 

You should always make sure all components are available to buy  (such as the PCB) before ordering anything, it can save cost in the long run. :)

Take care because between EA board révision there is difference in the position of the central pins which make the core not compatible with it, the good révision is B if I remember well, C doesn't match.

Ask for the révision before order it.

Thank you for your advice.

Interesting, I didn't know that. I have one more LPC core that I plan to stuff. Does anyone happen to know if LPC1769 revision D, currently available on the embeddedartists site, is compatible with LPC core? They claim that:

"the expansion pins (2x27 positions) are mechanically compatible with the original design"

but I'd like to check if anyone here has experience with it before I order.

Maybe the core was revised too, since I bought it. But, mine is only compatible with rev B.

I'm pretty sure, Lextronic has a stock of revB, but ask them before.

Or buy this D because it’s better than C?

C doesn't fit. 

D: no experience with it. 

Totally no fit or just the end part?

If you don't like to do "trial and error"-work DIY might not be the best thing for you to do.

Hello,

A = B = fits exactly the ucapps core board footprint.
C = D = don't fit exactly the ucapps core board footprint.

=> for C and D we need to use wire or to bend a part of the header.

Sorry if I wasn't clear before.

For all cases bootloader is the same method, except that you will maybe need to advise Memory address at burn, depending on version of your LPCXpresso ide, see http://midibox.org/forums/topic/20590-lpcxpresso-ide/

Best

You can use the D. If you do not solder it first you do not have to bend or use wire. there is enough flex in the header and sockets to get it to line up and once it is aligned you solder. If you solder first you will need to bend the pin legs or replace them with wire. It is a bit tricky to do but it does work.
