Ochin Tiny Carrier Board with Raspberry Pi Compute Module 4 - 2GB RAM, 32GB eMMC, 2.4/5.0GHz Wi-Fi & Bluetooth 5.0

This kit includes an Ochin_CM4 board and a Raspberry Pi CM4 module with 2GB LPDDR4 RAM and 32GB eMMC. The Ochin_CM4 board is a carrier board for the Raspberry Pi CM4 module and is 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.

• 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

Description

The Ochin CM4 designed by Flavio Ansovini 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 ochin_CM4 does not have a slot for the microSD, so it must be used with a Raspberry Pi CM4 module with eMMC, in this bundle, this version of the Raspberry Pi Compute Module 4 includes a high-performance 64-bit quad-core processor, 2GB LPDDR4 RAM, 32GB eMMC, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, Gigabit Ethernet, USB 2.0, dual camera interfaces, PCIe Gen 2 x1 interface, and dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0.

The dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0 have modular compliance certification. This allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Either the onboard antenna or an external antenna kit can be used.

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.

Note: The Raspberry Pi CM4 module gets pretty hot very quickly, please use an adequate heatsink.

• Aluminum Alloy CNC Heat Sink without Fan for Raspberry Pi CM4 Module: It provides better heat dissipation through passive cooling while protecting the compute module
• Aluminum Alloy CNC Heat Sink with Fan for Raspberry Pi CM4 Module: It also provides faster cooling through active cooling using a PWM fan.

Please refer to the gitbook for its installation and connection.

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.
