KEHIPI FNK0091 Breakout Board for Freenove ESP32 / ESP32-S3

SKU CH-GHBH-385N6

Breakout board with terminal blocks and pin headers exposes every GPIO on compatible Freenove ESP32 and ESP32-S3 boards, adds 5 V and 3.3 V power rails up to 3 A.

  • Plug in Freenove ESP32 boards for instant GPIO breakout
  • See pin state at a glance with on-board status LEDs
  • LEDs driven by the chip so GPIOs stay unaffected
  • Get multiple 5 V and 3.3 V rails, 5 V up to 3 A with external supply
  • Screw terminals and 2.54 mm headers expose every pin

Purpose-built breakout for Freenove ESP32 boards

The KEHIPI FNK0091 breakout board gives Freenove ESP32 and ESP32-S3 developers a solder-free way to reach every GPIO. It plugs directly onto compatible Freenove modules such as the FNK0060, FNK0090, FNK0085 and FNK0099. A 2.54 mm pitch terminal block and matching header expose all pins for quick wiring. An on-board LED driven by the chip shows logic state without loading the GPIO.

Makers who need fast GPIO access on supported

This shield suits hobbyists, educators and prototype engineers who already own a listed Freenove board and want instant access to power rails and signal pins. Builders using ESP32 or ESP32-S3 boards from other vendors cannot use this HAT because the pinout differs. Projects that demand a different form factor or integrated wireless antennas should look at other hardware.

Pinout locked to Freenove ESP32 / ESP32-S3 series

The single specification that decides fit is the pin arrangement: this breakout matches only the Freenove ESP32-WROVER, ESP32-WROOM, ESP32-S3-WROOM and ESP32-S3-WROOM Lite boards listed above. Any other module, even with the same chip, will not align with the 2.54 mm terminal block and header. Verify your board model before purchase.

Questions sur cet article

Which Freenove ESP32 board must I already own to use the FNK0091 breakout?

The FNK0091 works with Freenove ESP32-WROVER board FNK0060, ESP32-WROOM board FNK0090, ESP32-S3-WROOM board FNK0085 or ESP32-S3-WROOM Lite board FNK0099.

Will the 2.54 mm terminal blocks on this HAT still let me connect older 0.1 inch sensors?

Yes, the 2.54 mm pitch matches the 0.1 inch standard so existing sensors plug straight into the terminal blocks.

How can I verify the GPIO LEDs are showing live pin state after I power up?

Each LED lights when its GPIO reads high and stays off when the pin reads low; the LEDs are driven independently so they never load the GPIO.
