ESP32-S3R8 dual-core microcontroller board

This development board uses an ESP32-S3R8 chip with a Xtensa 32-bit LX7 dual-core processor running at 240 MHz. It integrates 512KB SRAM, 384KB ROM, 8MB PSRAM and 16MB Flash memory. Integrated 2.4GHz Wi-Fi and Bluetooth 5 (LE) provide wireless connectivity with an onboard antenna. The board targets developers building networked camera or IoT projects.

W5500 Ethernet plus PoE and camera interfaces

An onboard W5500 chip adds a 10/100Mbps RJ45 port via SPI, and an optional PoE module enables IEEE 802.3af-compliant Power over Ethernet. A dedicated camera interface supports the included OV2640 module as well as OV5640 sensors for image and video capture. USB Type-C handles power, programming and debugging, while a TF card slot stores captured files. Pico-compatible headers expand peripheral options.

16MB Flash and 8MB PSRAM for buffered imaging

The 16MB Flash and 8MB PSRAM combination holds firmware and frames from the OV2640 camera during capture or streaming. Ethernet at 10/100Mbps and 2.4GHz Wi-Fi move data off the board, but sustained high-resolution video may saturate the 100Mbps link. PoE removes the need for a separate power supply when a compliant switch or injector is present. Projects needing faster wired throughput or higher-resolution sensors will exceed the available bandwidth.

Questions about this item

Does the 240 MHz ESP32-S3R8 throttle during long camera captures?

The board runs at 240 MHz with 8 MB PSRAM and 16 MB Flash; sustained loads may hit thermal limits before the chip throttles.

How hot or loud does the W5500 Ethernet plus PoE module get in 24/7 operation?

No active cooling is fitted; the W5500 and IEEE 802.3 af PoE module run passively, so heat stays low and noise is silent.

What power source must I already have to use the PoE feature?

An IEEE 802.3 af compliant PoE switch or injector supplying up to 100 Mbps over the RJ45 port is required.
