STM32WL QFPN package reference design and board layout ?

[HK]

I want to make custom stm32WL board layout with antenna path. I found NUCLEO-WL55JC. This board has BGA package for stm32WL55JC.

Q1: I need stm32WL QFPN package board layout and antenna path. Is there board layout and reference design for stm32WL55CC (QFPN) ?

 

Q2: I see rf-shield for stm32WL55JC in NUCLEO-WL55JC board. What is ordering code of rf-shield and where can I buy this ? I shared rf-shield screenshot in attachment.

 

Thanks in advance.

Regarding files describing the layout of a reference design using the stm32WL55CC, I will check if we have something ready to deliver.

Regarding the RF shield, it is the same as the one use for the STM32WB microcontroller populated on the Nucleo board. It is a « home-made » design done by a very local company (Embest). I don’t know if they can be ready to distribute it. I will ask them.

Hi @Remi QUINTIN​ , any news about the QFN reference design ?

Olá @RFerr.3​ ,

Attached the file for QFN Ref. Board.

The schematics with the RF BoM PDFs are under "Manufacturing\3.2. Schematic, Assy & 3D PDF\Schematic\".

Att,

Thanks @Hamilton DC​ 

With this example project i could manage to project a 2 pcb layer using all gpio!
