Hi there,

I am currently working on a project using Teensy4.0. But I kinda need to integrate the Teensy 4.0 dev board into my customized PCB. I read through the doc on the website how to DIY Teensy LC, 3.2, 3.5, 3.6. https://www.pjrc.com/store/ic_mkl02.html.

I've noticed that Teensy 4.0 is using the same bootloader chip as Teensy 3.6, IC_MKL02Z32_QFN16. But Teensy 4.0 seems also to have an external flash memory W25Q16. I'm just wondering does the bootloader chip that is selling on the website would also work for NXP iMXRT1062 MCU, Teensy 4.0 is currently using? Or I would also be required to add the external flash memory W25Q16. Or maybe in the future, is there any chance u guys will post some documentation about how to DIY Teensy 4.0?

It would really appreciate if you could offer some here. I would have a relatively high quantity demand if I can DIY Teensy 4.0.
