CM_ESP_P4_C5 Open Hardware Edge Vision Platform

What is CM_ESP_P4_C5?

A clean, production-style development kit for embedded vision, HMI panels, gateways, and control systems.

At the heart of the platform:

• CM_P4-A1-N16R32
  A compact ESP32-P4 SOM with dual-core RISC-V up to 360 MHz, dedicated low-power controller, integrated 16 MB Flash and 32 MB PSRAM, and hardware blocks for ISP, JPEG, H.264, and display.
  Exposes MIPI CSI-2 camera, MIPI DSI display, RMII Ethernet MAC, USB 2.0 HS/FS OTG, I²S audio, CAN/TWAI, SDIO, SPI, I²C / I3C, UART, ADC, touch.
• CM_ESP32-C5-WROOM-1-N8R8
  An ESP32-C5 module with single-core RISC-V up to 240 MHz, dual-band Wi-Fi 6 (2.4 GHz and 5 GHz), Bluetooth 5 LE, Thread, Zigbee (802.15.4), 8 MB Flash, 8 MB PSRAM.
  Can act as the wireless / connectivity brain or as a companion coprocessor.

Both modules sit on the same carrier board. The result is a hybrid platform: high-performance vision and UI from ESP32-P4, plus next-gen wireless and mesh from ESP32-C5.

Camera system

Why cameras matter here

This platform is camera-first. Everything else (display, network, enclosure, BOM) is built around getting images from a sensor into silicon cleanly and repeatably.

Camemake camera module ecosystem

We maintain a standard camera pinout and connector. That same pinout is reused across our development kits. You can move camera modules between boards without rewiring or re-spinning a carrier.

You can choose from 31 supported camera modules sold on camemake.eu:

• All standard RPI-compatible camera modules
• The two DVP modules
• The SPI camera module
• Multiple resolutions and optical stacks

This gives wide coverage:

• High-bandwidth sensors over MIPI CSI-2
• Lower-cost sensors outputting already-compressed frames over DVP or SPI

Dual-path camera support on the kit

• The ESP32-P4 SOM (CM_P4-A1-N16R32) connects directly to MIPI CSI cameras. This is ideal for higher resolution and high frame rate.
• The ESP32-C5 module (CM_ESP32-C5-WROOM-1-N8R8) connects to DVP and SPI camera modules, where the sensor or module-side encoder handles compression.

This split means you can prototype:

• High-end streaming camera (CSI → hardware ISP / H.264 on P4)
• Low-power / low-cost camera node (DVP or SPI into C5)
  on the same board.

No other dev kit in this class gives you both camera paths live on one carrier, with published design files.
