Compute Module Carrier for Raspberry Pi Back Panel
Industrial-grade 4–20mA analog output card with 8 channels, source or sink mode. Stackable with Back Panel for Raspberry Pi automation systems.
The Sequent Microsystems Back Panel for Raspberry Pi introduces a powerful and scalable platform for industrial automation. One key enhancement is the ability to replace the standard Raspberry Pi with a Raspberry Pi Compute Module—ideal for embedded and custom applications.
The Compute Module Carrier for the Back Panel is a purpose-built carrier board that allows direct integration of the Compute Module into the Back Panel system. It offers the same I²C and GPIO connectivity as a full-size Raspberry Pi while providing a more compact, robust, and production-ready solution for industrial environments.

DESCRIPTION
The Compute Module Carrier for the Raspberry Pi Back Panel is a compact, industrial-grade solution that replaces the standard Raspberry Pi with the Raspberry Pi Compute Module 4 (CM4). Designed specifically for seamless integration with the Sequent Microsystems Back Panel, the carrier provides full support for I²C communication, GPIO26 interrupt signaling, and 24V power input. It features built-in Ethernet, dual-band Wi-Fi, USB-A and USB-C ports, an HDMI 2.0 output (up to 4Kp60), and an on-board temperature-controlled fan for efficient cooling. Ideal for embedded automation and control systems, the CM4 Carrier offers a robust, production-ready alternative for industrial environments
Power Requirements
The Compute Module Carrier card is powered by 5V delivered through the Back Panel power connector. The connector can supply up to 1,400 mA, meeting the peak power requirements of the Raspberry Pi Compute Module 4 (CM4). The typical power consumption is 400mA
Error Processing
Any card installed on the Back Panel can trigger an interrupt on the Compute Module by pulling pin 37 (GPIO26) on the GPIO connector low. The user is responsible for implementing the corresponding interrupt handler in software.
The Compute Module Carrier requires 5V power supply and up to 1,600 mA. The power is provided by the Back Panel

FAQ
Q: What is the Compute Module Carrier for?
A: It replaces the standard Raspberry Pi with a Raspberry Pi Compute Module 4 (CM4), enabling a compact, industrial-grade alternative for Back Panel integration.
Q: Is this carrier compatible with all CM4 variants?
A: Yes, it supports all Raspberry Pi CM4 versions, including models with and without onboard wireless.
Q: What interfaces are supported?
A: The carrier provides full GPIO access, along with Ethernet, dual-band Wi-Fi, USB-A, USB-C (host), HDMI 2.0, and support for RS232, RS485, and CAN signal routing.
Q: How is the carrier powered?
A: It receives 5V from the Back Panel power connector and can supply up to 1,400 mA to the CM4. Onboard regulation and protection are included.
Q: Is an interrupt line available to the Compute Module?
A: Yes, GPIO26 (pin 37) on the GPIO connector is reserved as a shared interrupt line. Any card on the Back Panel can assert it; the user must provide the interrupt handler.
Q: Can I use the CM4 Carrier with all HOP cards?
A: Yes, it is fully compatible with all Sequent Microsystems HOP (Hardware On Panel) I/O cards and supports up to 8 cards per Back Panel.
Q: Does the carrier include cooling?
A: Yes, it features an onboard temperature-controlled fan for reliable thermal management in industrial environments.
Q: What resolutions does the HDMI port support?
A: The HDMI 2.0 port supports hot-plugging and resolutions up to 4K at 60Hz (4Kp60).
Q: Is external PLC communication supported?
A: Yes, the carrier enables RS485-based MODBUS RTU communication, making it compatible with many industrial PLCs.
Q: What are the export restrictions for this product?
A: The product is classified under ECCN EAR99 and is freely exportable under U.S. regulations.
