LRE8x2 096 SSD1306-BAR for Eurorack V2
I made this PCBs to use it with Fairlightii´s mb-lre8x2cs_pcb
PCB
I didnt panalize it, so you have to do this when ordering the PCB online
you will need 4 PCBs per LRE8x2… normally you want to order 8 PCBs (using 2x LRE8x2)
Here are the gerberfiles for production - i made it withJLCPCB
lre-oled-bar2-gerber.zip
These are the settings, if you want to V-Groove it you have to panalize it at 2×4 PCBs at one pcb.
the minimal order is 5 PCBs… so you may have then 4 sets left that you can sell or make a present for anyone…
If you use EuroPacket as shipping method you will pay 26€ / thats incl import duty and taxes!
Hardware Requirements
- aMIOS32-Core to connect too
- DisplayDriver-SMD which buffers the Displays, they are already assambled, and 5 pieces costs around 60€ - you only need 1 PCB here (60/5=12€) - the 4 left you will definitfly need some time…
- Soldering Iron - with a Dip that can Handle Thruhole-Parts, solder Paste…
- mb-lre8x2cs_pcb for its nature use
- LRE5-LCD2 as UI to handle Patch management and automation (if you want to use my code…)
- You may need a DINX4 Module, in order to get the encoders inbuilt Pushbotton to work
- If you have not already - you will need a IDC-Crimper for all your Midibox Cables reichelt
Shematic
Building and BOM
Following Quantity is for 1 PCB (you may need this up to 8 times!):

2x 8Pin Ribbon Cables (i recommend to order a lot off them)
2x M3 Black Screws - cant remember the length - 1,5cm is enough
2x M3 Black Acrylic Spacers - cant remember the right length - i guess 6mm? mouser
2x M3 Nuts
