Flavio Ansovini’s Ochin Compute Module 4 carrier board with rich interfaces
There have already been a ton of carrier boards specially designed to hold the famous Raspberry Pi Compute Module 4. Yet another interesting tiny carrier board from designer Flavio Ansovini comes onto the market, sold on Seeed Studio. This tiny Ochin carrier board for Raspberry Pi Compute Model 4 is equipped with the powerful Quad-core Cortex A72 CPU and GPU, featuring a significant RAM size, CODECs, and graphic accelerators. For applications where there is limited space and weight containment is crucial, the carrier board’s tiny form factor is quite appealing. The carrier board is intended for many applications, including IoT, robotics, and home automation.
All Raspberry Pi CM4 is supported with an eMMC storage compatible with the board, allowing a transfer rate of up to 100 MB/s, which is four times as fast as CM3+. Depending on your requirements, you can choose a CM4 module with an SDRAM starting at 1GB up to 8GB and an eMMC at 8GB up to 32GB, with or without Wi-Fi and BT4 connectivity.
Specifications of the Ochin CM4 carrier board:
- Processor: Quad-core Cortex-A72, ARM v8 64-bit SoC clocked at up to 1.5GHz, and a Broadcom BCM2711
- Resolution: H.265 (HEVC) up to 4Kp60 decode, H.264 (up to 1080p60 decode, 1080p30 encode)
- Graphics: OpenGL ES 3.0
- Camera interface: 1x 2-lane MIPI CSI camera port and 1x 4-lane MIPI CSI camera port
- Serial communication: 1x USART, 3x UART, 1x I2C port, 1x SPI port
- USB ports: 1x USB 2.0 port
- Power: 7.5V to 28V with support for 2S to 6S lithium-polymer batteries
- Dimensions: 55x40x4.7 mm
One of the major highlights of the Ochin CM4 carrier board is the small form factor, which is almost of the same size as the original Raspberry Pi Compute Module 4. This reduces the overall footprint to result in a more compact form factor suitable for its integration into other embedded devices. Furthermore, the hardware is tested to work with the open-source software, OpenHD that allows the transmission of a low-latency HD video stream from a mobile station to a ground station.
The board is available for purchase at the Seeed Studio for $59.90, excluding the Raspberry Pi Compute Module 4. Also, a quick start guide on flashing the CM4 module, a manual for the board, and some tips on how to connect to the Ochin board can be found in their GitHub repository.
