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.

Features : 

• 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

Here we are introducing this new öchìn CM4 carrier board and its story! Flavio Ansovini is an enthusiast of electronics, robotics, and programming, and in recent years he has applied his skills to the world of RC models and drones. To make the most of the Raspberry Pi CM4 module he decided to create a carrier board oriented to robotics, drones, IoT devices, and in general embedded devices.

The Ochin CM4 has been licensed to Seeed to manufacture and sell. Flavio will provide the tech support and Seeed will fulfill the order with hardware quality guaranteed.

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.

• Raspberry Pi Camera Module V2: It carries an 8-megapixel Sony IMX219 image sensor with high resolution and great performance
  
• Raspberry Pi Wide Angle Camera Module: Raspberry Pi Wide Angle Camera Module is a low-cost Fisheye Lens, wider Field View, Camera module, designed for Raspberry Pi
• IMX219 M12/CS mount CMOS Camera Module: This IMX 219 CMOS camera module is based on the high-resolution Sony IMX 219 sensor and supports both M12 CS mount lenses.

Moreover, this Ochin CM4 carrier board is perfect for your robotic project due to the following features:

• Its compact design which has the same size as the Raspberry Pi module
  
• Ochin_CM4 embeds a dc-dc regulator that provides up to 7Amp. You can supply the board directly by connecting a LiPo battery (from 7V to 28V) and it will also supply the connected devices, even for a power-hungry USB device.
  
• On the Ochin_CM4 board, there is a GHS connector for almost every peripheral, no more picking up the signal from a strip and sharing the grounds and supply pins. In real applications you want a connector with signals and supply for every peripheral, it more clean and safe!
  
• Ochin has a current switch on the USB VBUS, so the +5V on the USB will be cut if the drawn current reaches the threshold of 3A. It's a protection circuit necessary to keep the CM4 on if you have a short on the USBs devices.
• Ochin_CM4 has two CSI camera connectors that you can use for two 2 CSI cameras and others on the 4x USBs if you need them.
