LORDWORLD ESP32-S3 Mini Development Board 2-Pack

SKU CH-91Y2-4GFEP

Two ESP32-S3 mini boards with dual-core processor, 2.4 GHz Wi-Fi and Bluetooth 5 for IoT prototyping

  • Dual-core processor at 240 MHz for responsive edge computing
  • 4 GHz Wi-Fi and Bluetooth 5 enable wireless IoT connectivity
  • 34 GPIO pins with SPI, I2C, UART, I2S, ADC for flexible peripheral interfacing
  • 512 KB SRAM, 384 KB ROM, 4 MB Flash and 2 MB PSRAM support larger firmware
  • Castellated module with ceramic antenna allows direct soldering to custom carrier boards

Dual ESP32-S3 boards for compact IoT prototypes

Two mini development boards built around the Xtensa 32-bit LX7 dual-core processor running at up to 240 MHz. Each board provides 512 KB SRAM, 384 KB ROM, 4 MB Flash and 2 MB PSRAM. The pair suits makers, students and engineers building Wi-Fi and Bluetooth 5 LE connected devices.

Wireless limited to 2.4 GHz 802.11 b/g/n only

The radios operate solely on the 2.4 GHz band with 802.11 b/g/n support, so 5 GHz networks are not an option. Bluetooth 5 LE handles low-energy peripheral links. Throughput and range follow the constraints of these standards in congested environments.

Castellated edges and ceramic antenna for direct

Castellated module pads let you solder each board straight onto a carrier PCB without headers. The onboard ceramic antenna keeps the footprint small. A USB Type-C port provides the serial link and power, while 34 GPIO pins expose 4 SPI, 2 I2C, 3 UART, 2 I2S and 2 ADC channels.

Perguntas sobre este artigo

Which pack size should I choose for prototyping multiple ESP32-S3 boards?

The listing supplies two identical boards so you can develop and test a primary unit alongside a spare or a second node without ordering twice.

What does the 240 MHz dual-core processor deliver in a real project?

The Xtensa 32-bit LX7 dual-core running at up to 240 MHz handles Wi-Fi, Bluetooth 5 and peripheral tasks concurrently while leaving headroom for application logic.

How does the USB Type-C port limit data throughput?

The onboard USB serial controller runs at full-speed USB rates so flashing and debug traffic are capped at 12 Mbps.
