Technical overview
- Resolution 320 × 240 pixels, IPS panel, 262K RGB colors
- Display area approx. 57.60 × 43.20 mm; board dimensions 70.20 × 50.20 mm
- Driver IC ST7789VW, supports RGB565 and RGB666 color formats
- SPI communication with tested maximum write speed of 60 MHz
- Onboard touch controller XPT2046 for resistive touch detection
- MicroSD slot for storing and directly displaying images
- Supply voltage 5 V; maximum power consumption approx. 140 mA
- Supported development environments: Arduino IDE, VS Code/CMake, and Thonny (MicroPython)
Notes and version constraints
- Verify exact pin mapping before connecting; the USB side of the Pico should face the same direction as the MicroSD slot
- Before testing image display via SD card, copy image files to the root directory of a FAT-formatted card; image resolution must be 320 × 240
- The MicroPython example does not support image display or rotation due to limited firmware memory; use C instead
- Compatibility with Pico W is not available because Pico W firmware limits available memory
- Demo codes reference specific library versions (TFT_eSPI); other versions may behave differently
- No information on certifications, warranty, or safety compliance is present in the source material
