Recommended gear

Tools and parts that work well for the projects on this site. We pick cheap things that are easy to find in big stores.

Displays

The most common small screen: four wires, crisp text, many libraries.

A narrow strip screen for one or two lines of status.

A bigger OLED with the same wiring, easier to read from a distance.

A bright color square screen on SPI for clocks and dashboards.

A cheap color screen, enough for menus and simple graphics.

A big touch screen for any ESP32 when you need more than a CYD.

Keeps the picture without power, perfect for battery dashboards.

Two lines of 16 characters on just four wires.

A bright running line for clocks and tickers.

Big digits for timers and clocks on two wires.

Some store links are partner links: the site gets a small share of the purchase, the price stays the same for you.
