I just finished soldering all of the components to the PCB and I found out I missed a track from Teensy's VIN to the VCC of the display and all I got was the backlight LED, after a little troubleshooting with the multimeter continuity mode and reviewing my designs I added a wire (the yellow one in the photos below) going from VCC to VIN and it worked!

Btw this is my 1st try with a hot air soldering station and it went great, I used it to solder the 120 Ohm SMD resistors on the board. The rest of the components were soldered using a normal iron.

Here are some photos along the way, enjoy!
