Using a Transparent Graphical OLED Breakout (LCD-15173) with a SparkFun ESP32 Thing

Hi there, would anyone have a basic circuit diagram (just pin to pin would be fine) for connecting the SparkFun Transparent Graphical OLED Breakout (LCD-15173) SPI to a SparkFun ESP32 Thing - not the Plus (DEV-13907) using the “HyperDisplay Library”, “HyperDisplay SSD1309”, “HyperDisplay Transparent Graphical OLED” with the settings…

Option 2 (SPI):

Connect SCLK and MOSI to the SPI port of your choice (13 and 11 for SPI on Uno-like boards)

Also connect D/C and CS to two unused GPIO pins of your choice (and set the proper pin definitions below)

Don’t forget power - connect 3.3V and GND

#define USE_SPI 1 // Choose your interface. 0 = I2C, 1 = SPI

I could swap to a ESP32 Thing Plus and follow the hookup guide is thats a better way. Many thanks Jon

You can find the graphical pinout for the ESP32 Thing here: https://cdn.sparkfun.com/datasheets/Wir … hingV1.pdf. You’ll need to connect the following in a one to one configuration:

MISO → MISO

MOSI → MOSI

SCK → SCK

CS and D/C will be connected to GPIO pins of your choice.

You’ll also need to disconnect the jumper on the backside of the OLED board to enable SPI
