KEHIPI
Dual-core 32-bit board with 16 MB Flash, 8 MB PSRAM, onboard camera, Wi-Fi and Bluetooth 5, plus tutorial projects and a 1 GB memory card
The KEHIPI ESP32-S3 CAM board is a compact IoT edge device built around a dual-core 32-bit microprocessor clocked at 240 MHz. It integrates 16 MB Flash, 8 MB PSRAM, 2.4 GHz Wi-Fi and Bluetooth 5, plus an onboard camera. The kit includes a 1 GB memory card for local file storage and targets makers learning embedded vision or wireless projects.
This board replaces simpler single-core modules that lack integrated wireless or camera support. The jump is worth it when a project needs simultaneous Wi-Fi and Bluetooth 5 connectivity, on-device image capture, or the headroom of 16 MB Flash and 8 MB PSRAM for larger firmware or MicroPython scripts. Builders staying with basic GPIO tasks will not use these extras.
The board connects to a host computer via USB for programming in C or MicroPython using the supplied tutorial and example projects. It needs a host IDE and driver installed, and the included memory card slots directly onto the board for logging or frame storage. No external radio modules or camera wiring are required, freeing GPIO pins for sensors or actuators.

The board measures 85 mm in length; allow extra room for the USB cable, camera module and a 1 GB micro-SD card inserted in the onboard slot.
Install the USB driver and your chosen IDE, then connect the board via USB; the step people skip is putting the board into download mode before uploading MicroPython or C code.
The 1 GB micro-SD card supplied with the kit may wear out after heavy read-write cycles and should be swapped for a fresh card when errors appear.
