custom 2.2 pitft screen

by darkmoon3d on Wed Feb 06, 2019 3:57 pm

I'm prototyping out building custom pcb for 2.2" pitft screen. https://learn.adafruit.com/pigrrl-zero?view=all

Not having luck with current build so wanted to confirm if these are correct components. Have changed resistor size to 1206 to make soldering easier.

Last year there was bad batch of 2.2" screens with wrong component https://forums.adafruit.com/viewtopic.php?f=50&t=132799&p=665628#p665628 so wanted to make sure I was using correct component.

Most specifically am unsure if AXP803 and MMBT2222 are correct.
