라즈베리 CM 캐리어 보드 Ochin CM4
(Ochin CM4 -Tiny Carrier Board for Raspberry Pi Compute Module 4)
개요
- 본 제품은 라즈베리 CM 캐리어 보드 Ochin CM4 입니다.
- Raspberry Pi CM4 모듈과 같이 사용할 수 있는 제품으로 USB2.0 포트, MIPI CSI-2, USART, UART, I2C, SPI, 아날로그 비디오 출력을 지원합니다.
특징
- High-performance: Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- High Resolution Supported: H.265 (HEVC) (up to 4Kp60 decode), H.264 (up to 1080p60 decode, 1080p30 encode) and OpenGL ES 3.0 graphics
- Rich interfaces: 1×USB 2.0 port (highspeed);MIPI CSI-2: 1×2-lane MIPI CSI camera port, 1×4-lane MIPI CSI camera port; 1×USART, 3×UART, 1×I2C port, 1×SPI port, Analog Video Output
- Strong Compatibility: Compatible with raspberry pi 4 modules with faster eMMC flash with up to 100 MB/s transfer rate, 4x faster than CM3+
- Compact Design: Same size as CM4 module, 55mm × 40mm × 4.7mm
- The Ochin CM4 is a tiny carrier board for the Raspberry Pi Compute Module equipped with the powerful Quad-core Cortex-A72 CPU and GPU, which features a big RAM size, the CODECs, and Graphic Accelerators. It's designed for a wide range of applications such as robotics, home automation, and IoT projects.

The board is compatible with all Raspberry Pi CM4 modules equipped with eMMC. Depending on your needs, you can select a CM4 module with an SDRAM of 1GB, 2GB, 4GB, or 8GB and the eMMC of 8GB, 16GB, or 32G, with or without the Wi-Fi / BT4 connection.
The Ochin board has also been tested to work with OpenHD open source software. Thanks to OpenHD it is possible to transmit an HD video stream with low latency from a mobile station (rover, drone, plane, etc ..) to a ground station. This was possible thanks to the enormous work of the OpenHd community which we thank very much.
There are rich interfaces available on board including 1×USB 2.0 port (highspeed), MIPI CSI-2: 1×2-lane MIPI CSI camera port, 1×4-lane MIPI CSI camera port,1×USART, 3×UART, 1×I2C port, 1×SPI port, and Analog Video Output, all of which enable the Ochin CM4 to connect to external hardware at lower abstraction layers, closer to the physical world.
In terms of external dimensions, it's the same as the CM4 module which adopts a completely new mechanical standard. The overall footprint is reduced, resulting in a smaller and more compact form factor suitable for integration into products.
In this repository, you can find the manual of the board, a quick start guide for flashing the CM4 module, and a guide with some tips on how to make the connections to the öchìn board.
It is important to read them both before turning on the Ochin CM4 board, to know its characteristics and above all the sequence in which the signals are present on the connectors.
