The worlds smallest Game Boy cart flasher!

Requires https://oshpark.com/shared_projects/OUjmrtRg to flashing the firmware

BOM

1.1 Changelog:

• Added indicators for the chips and header to make the pcb easier to assemble

• Added indicator for LED positioning

• Reduced pcb height by 0.3mm

• Fixed positioning of cartridge reader guide holes

• Renamed IC1 and IC3 to make more sense

1.2 Changelog:

• Reduced pcb height by 1.4mm

• Relocated componetnts to fit within the new size

• Modified footprint for cart reader

• Replaced the crystal (ECS-60-32-5PXDN-TR) with FQ1045A-6.000 to as this component is only 1.7mm tall instead of 4.3mm

1.3 Changelog:

• Fixed incorrect crystal footprint

1.4 Changelog:

• Fixed incorrect wiring to crystal

1.5 Changelog:

• Replaced the micro usb port with a USB Type C port

• Removed the ISP header in favor of flashing using the cart bus https://oshpark.com/shared_projects/OUjmrtRg

• Replaced the crystal with one that is smaller and does not require 2 capacitors

• Removed redundant capacitors

• Removed the leds for TXD and RXD and their resistors

• Reduced board width by 0.3mm

• Reduced board height by 1.8mm

• Reduced board layers from 4 to 2, this cuts the price in half

• Reduced the size of the cart reader footprint, this now requires some trimming of the pins to fit
