What You’ll Need
- CFA10105 OLED Breakout Board
- An OLED display: the transparent, the white, or the yellow
- Seeeduino v4.2 board or equivalent (3.3/5v switchable Arduino Clone – 3.3v is necessary)
- USB cable (USB to micro USB such as WR-USB-27)
- Jumper cables such as WR-JMP-Y40 or WR-JMP-41
- Headers such as CFAPN01855
- Some code! You can use our demo code available on the product pages.
In this guide, we’re going to connect using the SPI interface. The CFA10105 ships with both the BS1 and BS2 jumpers open, which makes the “default” interface SPI. Let us know if you want a guide for a different interface!
STEP 1: Ensure the voltage selection switch on the Seeeduino is set to 3v3. Using 5v can permanently damage your display.
STEP 2: Wire it up! Using the table below, connect the CFA-10105 to the Seeeduino using the headers and jumper cables.
|D2, VEN, E, R/W||N/A||NC||Not connected|
|D3-D7||Not shown||Pull High|
STEP 3: Connect your Seeeduino to your computer using the USB cable and load your code!
