It is possible to provide the customer's circuit/layout information and have it checked by Silicon Labs engineers.

There are some parts that you can't know until you actually make the board, so doing a review does not guarantee wireless performance, but it does increase the possibility that you will get the performance you expect.

When requesting a review, please have the following ready:

① Circuit diagram (image such as png or PDF)

• Please write your comments in English
• In the case of PDF files, Silicon Labs may not be able to open the files due to font conflicts. If you are in a hurry, png etc. is safe.

② Layout diagram (image such as png or PDF)

• Separated by layers. (It is difficult to follow the signal when multiple layers are stacked with different colors.)
• Please write your comments in English.
• In the case of PDF files, Silicon Labs may not be able to open the files due to font conflicts. If you are in a hurry, png etc. is safe.

③Layout data (CAD data)

• It will be easier for me to follow the signal, so it would be helpful if you could provide it.
•  対応したビューワをSilicon Labs社が持っていない場合もありますので、その場合は「レイアウト図（pngなどの画像、あるいはPDF）」を使用させて頂きます。
