First build, before I order the parts, am I missing anything?

[RotiiK]

I'm about to order all the parts that I need for my first GBZ build, however, I just want to double check with you guys that there isnt anything missing in the build that I would need:

LIST

• Buttons and silicone pads fromm retromodding (im still looking, if anyone knows where I can get cheap buttons and silicone pads, please tell me)
• YaYa's gorilla glass screen protectors
• wermy's 3d printed button wells and mounts
• erik_gee's AIO button PCB
• Adafruit PowerBoost 1000 (do i need 1000 or can I just the 500? wermy's video had a 1000, but would it work with a 500?)
• 2500mA Battery
• MicroUSB Breakout board
• Power strip PCB from helder
• Long push button switches for L and R
• GB Speakers
• PCB for SPI screen
• SPI Screen
• Volume Potentiometer
• SPDT slide switch

Am I missing anything that I definitely need for this?
I also want to thank the guys on discord as they helped me a lot for general information

Just buy the powerboost 1000c just to on the safe side. If you want a cheaper boost module there's the Gearbest Powerboost which only cost around $2. I made a pinout guide for it you can view at http://www.tinkerboy.xyz/gearbest-power ... out-guide/.
