Ochin CM4V2: Tiny Carrier Board V2 for Raspberry Pi CM4

The industrial setting often calls for advanced performance while minimizing the circuit size. As Ochin V1 is reaching its end of life (EOL), Ochin v2 is a new mini carrier board for Raspberry with numerous advanced features over its preceding version.

The Ochin CM4v2 is a compact Raspberry Pi Compute Module carrier board, boasting a  Quad-core Cortex-A72 CPU and GPU. It has ample RAM capacity, CODECs, and Graphic Accelerators, tailored for various uses including robotics, home automation, and IoT endeavors.

What’s New?

Compared to its older version, the latest Ochin V2 contains a micro HDMI interface for video output. It has 2x general-purpose LEDs and an IN219 current sensor. UART 3/5 GHS connector (both interfaces) replaced by USB ext. GHS connector with USB 2.0, I2C, nRPIBoot, VOTG, 3.3V, and GND. 100Base-T Ethernet is available for Ethernet connectivity. Moreover, a current limiter bypass has also been added to the Ochin V2 baseboard.

Note that all of the primary features from version 1 are kept in the new edition, along with additional changes that make it more adaptable and fascinating for a wider range of applications. One example would be the micro HDMI connector, which allows it to be used with a monitor, making it useful in headless devices and user-side programs that provide more connectivity options. The transformer-less Ethernet interface is useful too. The USB-C port used is the flash eMMC (Embedded Multi Media Card). The module contains 2x CSI camera connectors and 4x USBs.

Ochin CM4v2 features:

• The upgraded module includes Broadcom BCM2711 and a Quad-core Cortex-A72 (ARM v8) 64-bit System on Chip (SoC) operating at 1.5GHz for processing.
• It supports high resolution of H.265 (HEVC) (up to 4Kp60 decode), H.264 (up to 1080p60 decode, 1080p30 encode), and OpenGL ES 3.0 graphics.
• Contains a set of rich I/O interfaces.
• Supports a 4-lane and a 2-lane MIPI CSI connector for the camera interface.
• Includes 6-pin SPI GHS connector or soldering pads for 10/100M Ethernet.
• 4-pin I2C GHS connector.
• USB ext GHS connector with USB 2.0, I2C, nRPIBoot, VOTG, 3.3V, and GND
• 14-pin expansion header with 2x UART, composite video out, Vin-/Vin+, GND.
• Supports Raspberry Pi Compute Module (CM4) with faster eMMC flash having up to 100 MB/s transfer rate, 4x faster than CM3+.
• It has the same size as the CM4 module (50mm × 40mm × 4.7mm).
