Description
This is a high-resolution 3.4″ square TFT display featuring 480×480 18-bit full-color pixels on an IPS panel, offering excellent color accuracy and wide viewing angles up to 80 degrees off-axis in any direction.
The display is driven by the ST7701S controller and supports TTL RGB ‘dot clock’ data input. Note that SPI is only used for configuring the display and cannot be used to draw pixels.
It features a 40-pin connector with a pinout unique from standard rectangular displays and includes a capacitive touch panel (FT6336U) with I2C and IRQ connectivity through the FPC connector.
This product is intended for advanced users with a microcontroller or computer capable of TTL RGB-666 display driving, such as the ESP32-S3 with octal PSRAM or a Raspberry Pi. It is not compatible with common microcontrollers like Feather or Arduino unless supported.
Important: This is the display module only; no PCB or controller board is included. Ensure your setup supports TTL RGB-666 display input before purchase.
