ESP32 Dual-core Microcontroller Board

This KEHIPI development board features an ESP32 WROOM module with a dual-core 32-bit processor running up to 240 MHz. It includes 4 MB Flash and 520 KB SRAM alongside onboard 2.4 GHz Wi-Fi and Bluetooth 4.2 connectivity. The kit targets makers and students learning IoT development through practical projects.

Learners Wanting Guided Wireless Projects

The board suits beginners who want structured MicroPython and C examples covering LED, RGB, Bluetooth LE and Wi-Fi modes. Builders needing a paper manual, additional sensors or a different microcontroller architecture should look elsewhere. Support is available from the supplier for troubleshooting code and hardware issues.

Dual-core 240 MHz Processor with 520 KB SRAM

The 32-bit dual-core MCU operating at 240 MHz with 520 KB SRAM determines if this board handles your real-time wireless tasks. Projects requiring more memory or a different core configuration will need alternative hardware. The onboard Wi-Fi and Bluetooth 4.2 radio supports the included station, AP and TCP/IP examples.
