Hi, guys.
I want to use a W25Q256 SOIC16 flash ship with the Teensy 4.1 and I thought I could try making a breakout. The idea is similar to the one of this post, but in my case, with the Teensy 4.1 and without using the Audio Board.
This is the pinout of the IC:
My idea is to use these pins on the Teensy 4.1:
The mapping would be the following:
Here is the design I have done:
It is my first design, so I would appreciate any insights or recommendations. Am I missing anything important there?
Thank you.

The mapping would be the following:
Code:
Pins 1, 2 ,3 and 9 of the W25Q256 go to 3.3V. I have added a decoupling capacitor of 0.1uF.
Pin 7 of the W25Q256 goes to pin 10 of the Teensy. I have added a 10K pullup resistor.
Pin 8 of the W25Q256 goes to pin 12 of the Teensy.
Pin 10 of the W25Q256 goes to GND.
Pin 15 of the W25Q256 goes to pin 11 of the Teensy.
Pin 16 of the W25Q256 goes to pin 13 of the Teensy.
