KEHIPI FNK0099A ESP32-S3 development board 16 MB flash

SKU CH-F6B8-NFJ3N

A dual-core 32-bit microcontroller board with 16 MB flash, 240 MHz speed, and onboard 2.4 GHz Wi-Fi plus Bluetooth 5

  • Dual-core 240 MHz processor handles demanding IoT tasks
  • 16 MB flash stores large firmware and data files
  • Onboard 2.4 GHz Wi-Fi and Bluetooth 5 enable wireless connectivity
  • MicroPython and C examples accelerate project development
  • USB connection with pre-installed IDE simplifies the programming workflow

Compact ESP32-S3 board for IoT prototyping

The KEHIPI FNK0099A development board integrates an ESP32-S3 WROOM module with dual-core 32-bit processor at 240 MHz, 16 MB flash and 8 MB PSRAM. It targets makers, students and engineers building wireless IoT edge devices who need a ready-to-program platform with onboard 2.4 GHz Wi-Fi and Bluetooth 5 connectivity.

Tutorial and dual-language examples accelerate

A step-by-step guide linked from the product box supplies several typical projects, while MicroPython and C code sets let developers choose their preferred language. This bundled material removes the need to search for separate examples and helps users move from first connection to working prototype faster.

16 MB flash and 8 MB PSRAM handle moderate

The memory combination comfortably stores application code, configuration data and runtime buffers for typical sensor-gateway or home-automation tasks. Projects requiring very large assets, heavy graphics buffers or extensive local logging will exceed the available flash and PSRAM capacity.

Preguntas sobre este artículo

What ongoing upkeep does the FNK0099A ESP32-S3 board require after deployment?

No scheduled maintenance is needed; the board has no moving parts or batteries, so only occasional firmware updates or physical inspection of the USB connector are required.

Which resource hits its ceiling first when the dual-core 240 MHz processor runs continuously at full load?

The 16 MB flash and 8 MB PSRAM limit how much code and data can reside on-device, so memory capacity becomes the first constraint under sustained heavy workloads.

How much heat and noise does the board produce when powered all day with Wi-Fi and Bluetooth 5 active?

The bare PCB runs silently with no fan; typical operation stays barely warm to the touch because the ESP32-S3 draws only modest current from the 5 V USB supply.
