LaskaKit ESPD-3.5" ESP32-S3 3.5" TFT ILI9488 CAP Touch Rev. 3.2

Product detailed description

New generation development board ESPD-3.5" (revision 3.2) combines the powerful ESP32-S3 with a high-end 3.5" TFT display with capacitive touch and wide viewing angles. Compared to common low-power modules, it offers significantly higher performance, faster graphics rendering, and a perfect foundation for creating modern HMIs and smart devices. The board offers a microSD card slot for storing icons, two U.FL connectors for sensors, integrated Li-Pol battery charging, a built-in USB-UART converter, and battery voltage measurement.

3.the 5" display has a resolution of 480x320 px and the number of colours of each pixel can be up to 65535, and it also has a touch ESPD-3.5" includes a microSD card slot where you can store a lot of pictures and icons - you can find instructions on how to do it here.

In addition to the SD card slot, the board has an ESP32 module supporting Wi-Fi and Bluetooth connectivity, a built-in programmer with CH9102, a charging circuit for a battery with a charging current of 400mA, 2x uŠup connectors for connecting sensors (e.g. SHT40 - temperature/humidity, SCD41- CO2/temperature/humidity or BME280 - pressure/temperature/humidity). And now also a digital audio amplifier for playing system sounds.

The USB-C connector is used for both programming and charging the Lipolka. We also left a place for a 580mAh Lipol battery on the board - so it wouldn't get in the way anywhere else.
