YOUR PROJECT NAME UwU status! A OLED breakout board for #infill! The budget is 4.2$. The main challenge is finding the correct pinout connector!
- BIIIIGGGG print bed 310x310mm - Cheap! 160$ (Terms and conditions apply: you must be in china, shipping is costing me so much) - Cute! (I swear I'm going to make the 3d printed parts cute when they get here, and I need some pink filament but I ran out of budget :noooo:) Have removable cat ears on it :3 - Capable of printing figurines (Yes, don't judge me :3)
A super flat PG1316 keyboard - heavily inspired by mikefive and bayleaf, but aimed to make it even more compact and flat. Current PCB & PCBA price comes out at 65$! I will also shell out some money to buy additional parts :( Loved designing this! Had to learn how to make USB connections correctly, lipo charging circuit and bluetooth etc. V2 comming soon (tm)
