The Banano Board is a Arduino Nano-based universal controller board as featured in the ElectroBananas video:

This universal controller board can accommodate .96, 1.3 or 1.5" 4-wire I2C OLED displays. Can be used with a standard Nano, Nano IoT or ESP32 Nano variants. If you wish to order these boards from PCBWay, recommend that you request PCBWay to only provide and assemble the surface-mount components (the parts listed in the BOM as SMT/SMD type). This will keep the cost down and allow you to populate the other components as necessary to accommodate the needs of your projects.

So when ordering, state in the instructions: "Only provide and assemble SMT/SMD components".

Note! that PCB Way will offer a number of shipping options. This makes big impact on the overall price, so choose with care.

The BOM, Schematic, base-code (software) and prototyping case can be found in the sections below.

The board measures approximately 55mm by 85mm.

There is more information on the prototyping case here:
