SCINTIX P4 is an ESP32-P4 RISC-V Compute Module with an ESP32-C6 for wireless connectivity that’s compatible with Raspberry Pi CM4/CM5 carrier boards, at least partially.
It should be the first MCU-based system-on-module in Raspberry Pi CM4/CM5 form factor, and RELOC says the SCINTIX P4 gives access to displays, cameras, Ethernet, USB, and all the peripherals the ESP32-P4 exposes when connected to a carrier board. It can also be programmed in standalone mode through its built-in USB Type-C port.

While it looks neat, in practise, you’d lose HDMI and PCIe interfaces, USB is limited to 2.0 speed (480 Mbps), and Ethernet to 100 Mbps. It still exposes MIPI CSI/DSI camera and display interfaces and GPIOs. In our article about the ESP32P4C5 Core Board with two Raspberry Pi-compatible MIPI connectors, we noted that ESP32-P4 could only support the original Raspberry Pi Camera Module (OV5647), but not the more recent Sony IMX-based modules, and the situation is better for the official Raspberry Pi displays, although this requires an out-of-tree library, at least for now.
On the software side, it will obviously not run Raspberry Pi OS, and instead, RELOC mentions full compatibility with Espressif’s ESP-IDF SDK and demos, and Arduino and PlatformIO support out of the box. As an upcoming crowdfunding campaign, nothing has been released yet, but RELOC promises schematics, Bill of Materials, pinout diagrams, 3D mechanical models, firmware examples covering the main features of the board (Wi-Fi / BLE, Ethernet, display, camera, etc.), a complete demo project showcasing the full board capabilities, and component libraries compatible with CAD tools such as KiCad. There’s no video demo of the solution either for now.
RELOC has set up a page on Crowd Supply for a future launch, but I also noticed the product page on the RELOC website says that the SCINTIX P4 is available and to contact them for pricing.
