cartreader/extras/pcb

cartreader.zip is the main PCB, if you order it from JLCPCB you usually get a coupon displayed during the checkout for buying parts from lcsc.com. Default settings are fine, just select the color you prefer and off you go. If this is your first order from JLCPCB you should only pay $2 for 5 PCBs.

nes_adapter.zip is an add-on for reading NES carts, PCB thickness needs to be changed to 1.2mm, this is very important or else it won't fit into the SNES slot. You can order a 2.5mm 72pin NES slot here.

sms_adapter.zip is an add-on for reading Sega Master System carts. You can order a 2.54mm 50pin SMS slot here. Ignore the SMD footprints on the PCB, the adapter does not need any components.

flash_adapter.zip is an add-on for writing flashroms like the 29F032, 29L3211, 29LV160, PCB thickness needs to be changed to 1.2mm, this is very important or else it won't fit into the SNES slot.

eprom_adapter.zip is an add-on for writing an 27C322 eprom, PCB thickness needs to be changed to 1.2mm, this is very important or else it won't fit into the SNES slot.

With the sd_adapter PCB you can transform the microSD module from the parts list into a full size SD module by desoldering all the components and soldering them to this PCB. This is optional since you can also just mount the microSD module as is.

For Oshpark you need to rename filename.GML to filename.GKO or it won't find the board outline. Oshpark is great for ordering the smaller PCBs but very expensive for larger boards.
