1.3インチ SH1106 uOLEDディスプレイモジュール（ホワイト）

I swapped out the smaller 0.96" module for this 1.3" version and the extra screen real estate really helps when I'm reading text at a glance. The white pixels are crisp and the ultra low power draw means my battery lasts noticeably longer.

The larger screen makes a real difference when I'm squinting at sensor readouts—finally can see the 128x64 pixels without pulling out a magnifying glass. Hooked it up to my breadboard and it lit up immediately, no fiddly timing issues with the driver.

The 128x64 resolution is sharp even on this bigger screen, and the white pixels really pop against the dark background. I was worried the larger size might look pixelated, but it's perfectly crisp for text and basic icons.
