Which display shows text on Arduino?
The 0.96 inch OLED shows crisp text at 128 by 64 pixels over I2C.
It uses 4 pins: GND, VCC, SCL, and SDA. The blue, white, and yellow-blue modules all cost $7.49.
It takes 3.3V to 5V, so it suits Arduino and ESP32 boards with no extra level shifting. Update it once per loop so the numbers stay readable.
Which display shows color graphs?
The TFT display shows 65K colors in sizes from 0.96 to 2.8 inch.
It runs from $5.83 for 0.96 inch to $10.92 for 2.8 inch. It uses SPI with ST7735, ST7789, or ILI9341 drivers.
The 2.0 inch size costs $9.72, and the 2.4 inch size costs $9.72 too. Pick the TFT for graphs and color gauges that need more pixels.
Which display shows numbers with few pins?
The TM1637 shows 4 digits with only 2 pins, CLK and DIO.
It measures 0.56 inch and suits clocks, counters, and readouts with no graphics. The yellow module costs $6.21, blue costs $6.36, and green costs $6.48.
Wire it to any 2 GPIO pins and drive it with the TM1637 library. It leaves the most pins free for sensors.
Which board has a display built in?
The NodeMCU ESP8266 board has a built-in 0.96 inch OLED display.
It carries an ESP-12E chip with WiFi and a CH340 USB-serial chip over Micro USB. The board costs from $11.37, with blue at $11.37 and white or yellow-blue at $11.46.
The display sits on the board, so no wiring is needed for it. FLASH and RESET buttons sit on the board for programming and restarts.
Which board drives a display over WiFi?
The ESP32 DevKit V1 drives a display over WiFi for $11.99 listed.
It is a 30-pin WROOM-32 board with WiFi and Bluetooth. Its Type-C board costs $15.99, and its Micro board costs $17.99.
The SuperMini costs $9.99 to $17.99 by version with WiFi and Bluetooth. The S2 Mini costs $11.16 with 4MB of flash and 2MB of PSRAM.
