Two black-and-green ESP32-S3 boards with 44-pin expansion adapters

KEHIPI

KEHIPI ESP32-S3 Development Board 44Pin 8M PSRAM Expansion Adapter

SKU CH-SR8D-E6RZG MPN ESP32-S3

Expands each GPIO pin into two connections on a 44-pin board with 8 MB PSRAM and 2.4 GHz WiFi plus Bluetooth 5

  • Dual-core 240 MHz LX7 processor powers demanding IoT projects
  • 36 programmable GPIOs with 44-pin expansion adapter multiply connection options
  • 4 GHz WiFi 802.11 b/g/n and Bluetooth 5 enable long-range wireless links
  • Two pre-soldered DevKitC-1 boards plus two breakout boards ready for immediate development
  • 6 mm thick black-green PCB ensures durable reliable prototyping

Dual development kit with expansion boards

This kit supplies two pre-soldered ESP32-S3-DevKitC-1 boards and two GPIO breakout boards. Each development board integrates 2.4GHz WiFi and Bluetooth 5 with a dual-core LX7 processor running at 240MHz. The expansion boards double each GPIO pin, giving makers extra connection points for sensors and actuators.

Suitable for prototyping dual-node IoT projects

Engineers building mesh networks or redundant sensor nodes can use both boards simultaneously. Projects that require only a single microcontroller or need more than 36 programmable GPIOs per board should consider alternative hardware.

44Pin expansion adapter doubles GPIO count

The included breakout boards convert every GPIO on the 44Pin header into two accessible pins. This layout lets you reuse all 36 programmable GPIOs without soldering additional headers.
