Drop in replacement for OM13056

thomaspeter-volpi — Wed, 08 May 2024 12:43:46 GMT

We are trying to get a hold of a few OM13056 LPCXpresso boards (8 units max.), but none of the big distributors have it in stock.

Is there maybe a drop-in replacement for the OM13056 available? We have a custom PBC that is plugged onto the header sockets of an OM13056 and we would like to reproduce that setup.

Best regards

Thomas

Hi,

I have checked the OM13056 board, it is also called LPCXpresso1549, which uses LPC1549JBD64 processor.

I suppose that there is not Drop in replacement for LPC1549JBD64

It appears that you can order the silicon from the link:

https://www.nxp.com/part/LPC1549JBD64#/

For the OM13056 board ordering, pls try the website:

Hope it can help you

Hi XiangJun

I tried https://www.nxp.com/part/OM13056#/, but the major distributors don't have it in stock. I also don't need a drop in replacement for the board and its headers, not the chip LPC1549JBD64. If there is another LPCXpresso board with the same header interface that can run the same software as the OM13056 I would be happy with that.

Best regards

Hi,

If you just use Arduino header, it is okay, a lot of board has the Arduino header.

Can you tell us the header signals you are using?

This is how we use the Arduino header interface.

I suppose the OM13058 would work (https://www.nxp.com/part/OM13058#/), but I don't know how much we would have to change the firmware that was written for the OM13056 to be running on the OM13058. Or would it be pretty straightforward to port a firmware for the OM13056 to the OM13058?

Hi,

The OM13058 is based on LPC11U68, which uses Cortex-M0 core.

If you have the source code and just use GPIO, uart, ADC, I do not think the task is huge.

Hope it can help you

Is there another NXP MCU DevKit with Arduino headers that uses an ARM Cortex-M3 microcontroller?

Best regards

Other vendors like ST have Arduino-compatible headers as well.
Like most of their Discover and Nucleo boards.
However, I consider their "Cube" library/SDK a regular disaster.

Hi,

If the connector signals match between OM13056 and OM13058, porting the firmware is not a huge task, because all the code is written with C language.

Hope it can help you
