where is the GPIO37 and GPIO38?

[coollofty]

I need an 8-channel ADC, just GPIO32-39 can meet my needs, but GPIO37 and GPIO38 can't be found on the documentation. Where is the gpio 37 and 38?

These GPIOs are not broken out on modules such as WROOM and WROVER, but are available if you use the bare chip.
