Displays

Displays give your project a face — a way to show a reading, a menu, a status or a graph without a laptop attached. We stock OLED modules, character LCDs, TFT touch screens and seven-segment displays, in the sizes and interfaces that work cleanly with Arduino and ESP32 boards.

The practical trade-off is interface and pin count. A 0.96-inch or 0.91-inch I2C OLED is the easiest win in most projects: two data pins, crisp white-on-black text, readable in a dark room and well supported by libraries. A 16x2 or 20x4 character LCD costs less and is very readable for plain text, but wants more pins unless you add an I2C backpack, which is worth doing every time. A TFT touch screen — 2.4-inch through 3.5-inch — is what you need when the project deserves graphics, colour or on-screen buttons, though it will use SPI and a good deal more of your microcontroller's memory.

Check the operating voltage against your board before wiring, particularly on 3.3V ESP32 projects. All modules are tested before dispatch and available for pickup in Nairobi CBD or delivery across Kenya.
