This 1.3inch OLED display module is designed for Raspberry Pi Pico, 64x128 pixels, support PSI/I2C interface.
Working voltage | 2.6V ~ 5.5V |
Current | 40mA |
Controller | SH1107 |
Interface | 4-wire SPI / I2C |
Resolution | 64 x 128 Pixels |
Pixel size | 0.15 × 0.15mm |
Display area | 14.70 × 29.42mm |
Outline dimension | 52.00 x25.00(mm) |
This OLED integrates the SH1107 controller which has 128x128 bits SRAM, supports 128x128 resolution. The controller features SPI/IIC/ 6800/8080 interface and 256 brightness levels. The resolution of this 1.3inch OLED is only 64x128, only half of the SRAM is used.
This OLED uses four-line SPI and I2C interface for communicating, which supports higher compatibility and speed.
Note: The MISO pin is hidden, for more details, you can refer to Datasheet Page11.
CS: Chip selection of the slaver, the chip is activated when CS is Low;
SI(D1): This is MOSI pin, the pin is used to transmit data from master to slaver;
SCL(D0)is the SPI clock
A0: This is the DC pin, it is used to determine the data input, DC=0: command is sent;
SPI communication has data transfer timing, which is combined by CPHA and CPOL.
CPOL determines the level of the serial synchronous clock at an idle state. When CPOL = 0, the level is Low. However, CPOL has little effect on the transmission.
CPHA determines whether data is collected at the first clock edge or at the second clock edge of the serial synchronous clock; when CPHL = 0, data is collected at the first clock edge.
According to the figure, SCL is high in idle and it starts to transmit data at the second edge. therefore the timing is Mode 3 (0x11). Data is transmitted in MSB format.
Please take care of the direction when you connect Pico, an USB port is printed to indicate . You can also check the pin of Pico and the OLED board when connecting.
You can connect display according to the table.

Please refer to Raspberry Pi's guide: https://www.raspberrypi.org/documentation/rp2040/getting-started/
Open terminal and run the following command:
sudo apt-get install p7zip-full cd ~ sudo wget https://www.waveshare.com/w/upload/3/3d/Pico_OLED_code.7z 7z x Pico_OLED_code.7z -o./Pico_OLED_code cd ~/Pico_OLED_code cd c/build/
This guides is based on Raspberry Pi.
Open a terminal and enter the directory of C codes:
cd ~/Pico_OLED_code/c/
If the display you use is Pico-OLED-1.3, you need to uncomment the line OLED_1in3_C_test() and save it.
Create a build folder and add SDK:
For example, if the path of SDK is ../../pico-sdk
Then you should create build and add the path like these:
mkdir build cd build export PICO_SDK_PATH=../../pico-sdk #export PICO_SDK_PATH=/home/pi/pico/pico-sdk
Run cmake.. command to to generate Makefile file
cmake ..
Run make command to build.
make -j
We package the hardware layer for easily porting to the different hardware platforms.
