greetings,

i need the circuit schematics for micro oled circuit breakout with arduino pro mini 3.3v.

i cannot understand the connection given in the website with arduino pro.

Hello,

What communication protocol are you wanting to use?

3

i want i2c mode.

In order to connect the Pro Mini to the Micro OLED I would suggest you look at the [Hookup Guide and the [Pinout Diagram. To use I2C you’ll need the following connections:

Pro Mini => Micro OLED

VCC => VDD

GND => GND

SDA (A4) => DI (SDI)

SCL (A5) => DO (SCK)

*Note: please use caution when programming the Pro Mini with an FTDI Breakout. The Pro Mini 3.3V and the Micro OLED screen run on 3.3V, so if you accidentally use a 5V logic level then you can potentially cause damage to both boards. Its a common mistake.](https://cdn.sparkfun.com/assets/c/6/2/2/1/ProMini8MHzv2.pdf)](Using the Arduino Pro Mini 3.3V - SparkFun Learn)

sir i tried the connections but its still not working, the output in this 3v volts only and my pro mini is working fine.

Can you include a picture of your setup?

How are you powering the board?

7

Are you using the I2C code or the SPI code?

8

i tried i2c but its not working , so i thought spi would work

spi mode
