ESP32-S3 3.5" Capacitive Touch Display Dev Board (320x480)

This is a 3.5" ESP32-S3 all-in-one capacitive touch display dev board from Waveshare, packed with handy features, sensors and interfaces, making it a pretty versatile option for any ESP-based display project you're planning.

It's built around the dual-core ESP32-S3R8 processor, offering 2.4GHz Wi-Fi and Bluetooth 5 LE. It features a 3.5" capacitive touch IPS display (320×480), integrated 6-axis motion sensor, RTC, audio codec with plug-in 6Ω 1W speaker, and robust power management via the AXP2101 chip.

With onboard 8MB PSRAM, 16MB Flash, MicroSD card slot, camera interface, and rich peripheral support including I2C, UART, USB, and multiple GPIOs, it's ideal for embedded, media-rich applications.

The board also includes programmable buttons, a 1.25mm PicoBlade-compatible LiPo interface, and hardware support for camera modules such as OV2640 and OV5640.

We offer two versions of this product - the board only, or the board bundled with an OV5640 camera and a case. Select an option before adding to your cart.

Important! LiPo Connector Size

This board uses a tiny MX1.25/PicoBlade-compatible connector for LiPo power, however most LiPo batteries use a larger JST-PH fitting.

We now stock PicoBlade-compatible LiPo batteries in 150mAh, 500mAh and 1200mAh capacities - or you can customise your existing LiPo with one of our 1.25mm pitch cables (assuming you have the ability, knowledge and tools to do this safely!).
