TFT & LCD
Character LCDs, SPI TFT modules, large DSI and HDMI touch panels — about 185 parts covering most of the wired display spectrum.
16×2 and 20×4 character LCDs (parallel, I2C backpack, Qwiic, Grove), SPI TFTs from 0.71 to 3.5 inches, and large DSI and HDMI capacitive-touch panels up to 13.3 inches.
- Character LCDs differ on geometry and bus: bare parallel, I2C backpack, Qwiic, Grove plug-in, or Raspberry Pi keypad HAT — a 16×2 and a 20×4 are not pin-compatible even in the same bus family.
- SPI TFTs vary on resolution, driver chip, touch layer, microSD socket, voltage range and connector: a 1.8inch ST7735 and a 1.3inch ST7789 are different in every dimension except SPI.
- Large panels (4.3 to 13.3 inch) are mostly DSI for Raspberry Pi or HDMI/Type-C for general use; capacitive multi-touch, optical bonding and IPS panel specs vary per listing and matter for enclosure design.
- Waveshare contributes a large portion of the larger-format touch panels in this group, including 7, 8, 9.7, 10.1, 11.6, 12.3, and 13.3 inch HDMI and DSI variants with optical bonding and 10-point touch.

Known swap options (1)
General board checks (7)
- Decide whether the project needs a character LCD or a pixel-addressed TFT display. Do not cross that boundary without redesigning the UI and firmware.
- For character LCDs, match the character geometry first: 16x2, 20x4, or another size.
- Match the interface path: parallel pins, I2C backpack, Qwiic, Grove, Raspberry Pi HAT, SPI TFT breakout, raw TFT panel connector, or capacitive-touch module.
- For TFTs, confirm resolution, controller or driver family, SPI mode, color depth, touch controller, microSD wiring, library support and available MCU memory.
- Confirm supply voltage, logic level, I2C address or serial protocol, contrast/backlight controls, and current draw.
- Check board dimensions, mounting holes, connector position, keypad buttons, touch area, bezel opening and enclosure depth.
- Use the vendor product page and datasheet for the exact module before swapping into a finished design.
