You can refer to the following link for getting more information on Laird Connectivity-->
For the SPI speed query, refer to the following link-->
This link provides information on the Sterling-EWB IoT Module. Under the Documentation tab, you will get the datasheet for the module.
In the datasheet, you can refer to the section 9.3 "SPI Interface" for getting the SPI clock frequency under different modes.
Thank you for the quick reply.
The datasheet 9.3 is for MCU SPI specification.
I am curious about the maximum speed of the 2MB flash. Can it support SPI 25 or 50Mhz?
Could you provide the 2MB flash specification(about ID, block, sector, the support clock frequency, etc)?

The EWB uses the EON EN25QH16 flash in a die form.
Thank you so much!!!
Have a nice day.
