At a glance ## The OLED display, 1.3 inch SH1106 in brief What it is, and every setting the properties panel gives it. The 1.3 inch 128x64 OLED looks like a bigger SSD1306 and has the same four pins, GND, VCC, SCL and SDA, at the same 0x3C address, but its controller is an SH1106, and that difference is the whole story of this part. It runs from 3.3 or 5 volts with pull-ups on the module, wired to A4 and A5 on an Uno or GPIO 21 and 22 on an ESP32. The SH1106 has 132 columns of RAM for 128 of glass, bonded from column 2, so a driver has to start every page there; it has page addressing only, with no horizontal mode or column window; and its DC-DC converter starts on, with no 0x8D charge pump command. Mokxi models all three, so an SSD1306 sketch on it shows a picture two pixels out of place with a stripe of noise down one side, or every pixel piled into the top eight rows. Mokxi’s Adafruit_SH110X header drives it properly through Adafruit_SH1106G. U8g2’s SH1106 constructors are not included, and contrast reaches the picture as sixteen steps. Family Displays Pins 4 address 60 the I2C address, 0x3C by default. Pins ## 4 pins Named as the editor names them, so a wire lands where you expect it. Pin What it does GND Ground. VCC Supply, 3.3 V or 5 V. SCL Open-drain clock; the module has its own pull-up. SDA Open-drain data; the module has its own pull-up. How to use it ## How to use a 1.3 inch SH1106 OLED with an Arduino On its own, wire it like any I2C OLED: SDA to A4, SCL to A5, VCC to 5 V and GND to GND, at address 0x3C. Use Adafruit_SH1106G rather than Adafruit_SSD1306: call begin(0x3C, true), draw with the usual GFX calls, and send the frame with display(). The SSD1306 library gives a shifted, half-missing picture. The project beside this puts it on A3 and A2 instead, on a bus of its own, because the 128x32 SSD1306 next to it also answers at 0x3C. Its hand-written driver starts every page at column 2, which is the one thing an SH1106 driver has to get right.

The read-modify-write mode (0xE0, 0xEE) is accepted and does nothing, since nothing reads the RAM back. Contrast reaches the picture as sixteen steps. From SH1106 1.3 inch OLED, in full.

Full-size breadboard A real 0.1 inch grid with the rails and the center channel, 63 columns wide. Jumper wires Drag from any pin or hole to any other. Corners snap, and you can drag them. Power A supply rail at the voltage you choose. Ground The other end of every circuit. LED Lights when current flows. Five colors, and the brightness is what your eye would see. Filament lamp A tungsten bulb in a holder: an inrush when it is switched on cold, tens of milliseconds to warm up, and dim on half its voltage. Resistor Any value you like, with the color bands drawn to match. ESP32-C3-DevKitM-1 A RISC-V board that runs your firmware at 160 MHz on the real memory map. Pushbutton A 12 mm tactile switch. Hold it while the simulation runs. Raspberry Pi Pico The RP2040 board on our own Cortex-M0+ core. Pick a program and press Run. Raspberry Pi Pico W Raspberry Pi Pico W (RP2040). The same board and the same pinout as a Pico, with the CYW43439 on it. The WiFi is simulated (no radio; real internet through the Cloud panel’s switch), and the on-board LED, which hangs off that chip rather than off GP25, is driven through the same path. Everything else is the Pico. Raspberry Pi 4 Model B Raspberry Pi 4 Model B: the 40-pin header, driven by main.py with RPi.GPIO or gpiozero.
