I almost fried my seeed studio microcontroller!

Well, kind of. I forgot to put a resistor divider between my 5v op amp output and my 3.3v seeed studio nRF52840 microcontroller. I’ve now added two SMD resistors to the underside of the PCB. It’s getting really tight in the pcb (just look at the traces), but I really don’t want to make it any bigger.
I forgot to say from last time, but I also added a on off button (how did i forget that?), some mounting holes, and a BJT transistor to actually turn off parts of the circuit when in sleep. I think I will start modeling the case for it no because most of the elements in the PCB are done.
