Documentation for older versions (D-01) of the Nucleo WL55 board not available.

[BUdva.1]

Dear ST community,

I have 2 Nucleo WL55 highband boards and I suspect that there has been a mislabelling of the device. As I am aware of, only the D-04 version of this board is sold. However, my board has several pins that do not correspond to the ones mentionned in the datasheet. By looking closely at my device, I see that the sticker label mentions the D-04 version, however, on the PCB itself I see D-01 (see image below).

Is it possible to obtain the User manual and schematic for this version of the board? I cannot find it anywhere and it is really painful to probe each pin to reverse engineer the PCB connections.

Thanks in advance,

Balazs Udvarhelyi

Hello @BUdva.1​ 

Let me first welcome you to the STM32 Community 🙂

MB1389-D01 board was only internal boards used to prepare RF certifications. From those boards, the BOM has been tuned in order to have a MB1389-D04 BOM.

So, the revision D04 of the MB1389 which was RF certified, is the initially released version in production. And, I’m not in a favor to communicate schematic of MB1389-D01.

Regarding UM2592 which is available in the ST website, it is applicable (as the same) whatever the MB1389D boards.

Hope I answered your question 😊.
