Two black and green ESP32-S3 development boards with USB-C ports and expansion adapters

KEHIPI

KEHIPI ESP32-S3 N8R2 44Pin Type-C Development Board 2 Sets

SKU CH-6W5S-4DHQH MPN ESP32-S3

Two pre-soldered ESP32-S3 boards with 8MB flash, 2MB PSRAM, 240MHz dual-core processor, 36 GPIOs, 2.4GHz Wi-Fi and Bluetooth 5, plus two 44-pin expansion boards that double each GPIO

  • Dual-core 240 MHz processor handles demanding IoT tasks
  • 36 programmable GPIOs with expansion board doubling pin utility
  • 8 MB flash and 2 MB PSRAM store large firmware
  • Bluetooth 5 and 2.4 GHz Wi-Fi enable long-range wireless links
  • Two complete development kits included for parallel prototyping

Dual development boards for IoT projects

The KEHIPI ESP32-S3 N8R2 kit supplies two pre-soldered 44-pin development boards and two matching expansion boards. Each module integrates an LX7 dual-core processor running at up to 240 MHz with 512 KB TCM SRAM and 36 programmable GPIOs. The package targets makers who need ready-to-code hardware for Wi-Fi and Bluetooth 5 edge applications.

Low-power wireless with stable thermals

The ESP32-S3 chip combines 2.4 GHz Wi-Fi 802.11 b/g/n at 40 MHz bandwidth with Bluetooth 5 LE and Mesh, including Coded PHY for long-range links and 2 Mbps PHY for higher throughput. RF performance remains stable under high temperature, and the board draws power from either USB-to-UART or the native USB port. The 1.6 mm PCB and black-green finish complete the compact design.

Expands single GPIO pins to dual channels

The included breakout boards convert each GPIO into two usable pins, effectively doubling I/O availability without changing the MCU. This suits projects that exhaust the native 36 GPIOs on sensors, displays or actuators. Builders needing more than 8 MB Flash or 2 MB PSRAM, or requiring wired Ethernet, should evaluate alternative modules.

Vragen over dit artikel

How do I connect the KEHIPI ESP32-S3 N8R2 44Pin Type-C Development Board to my computer for programming?

Plug a USB-C cable into the board's USB port; the onboard USB-to-UART bridge appears as a serial port so you can flash firmware immediately.

What upkeep will the KEHIPI ESP32-S3 N8R2 44Pin Type-C Development Board need over time?

No scheduled maintenance is required; keep the PCB free of dust and moisture, and reflow any cracked solder joints on the expansion headers if they loosen after repeated use.

What thermal limit appears first when the KEHIPI ESP32-S3 N8R2 44Pin Type-C Development Board runs at 240 MHz continuously?

The LX7 dual-core processor will throttle or become unstable once its junction temperature exceeds the rated maximum, so sustained full-speed loads need adequate airflow or a heatsink.
