1 / 1Raspberry Pi 5 Model B, 8 GB Single-Board Computer
An 8 GB Raspberry Pi 5 Model B bare board for Linux, ROS 2, sensing and robot applications. Quad-core 2.4 GHz Cortex-A76 compute, PCIe/MIPI/USB 3.0 expansion and a 5 V / 5 A power requirement make it the high-level host — not the real-time motor controller. Power, cooling, storage, cables and mounting are separate.
- 8 GB for profiled multi-node workloads: Give ROS 2 nodes, logs, tools and camera pipelines more memory headroom after validating the actual workload.
- A compute host, not a motor controller: Keep Linux and high-level robotics on the Pi while a dedicated controller owns deterministic motor, encoder and safety I/O.
- High-bandwidth paths for a real robot: MIPI, PCIe 2.0 ×1, simultaneous USB 3.0 and Gigabit Ethernet support sensing, storage and integration choices.
- Power and cooling must be designed in: Use a 5 V / 5 A USB-C supply and active cooling for sustained work, then validate the final enclosure and peripheral load.

COMPUTE ROLE
Make this the Linux and ROS 2 host — not the real-time layer.
Raspberry Pi 5 runs the upper layer of the robot: ROS 2 nodes, networking, visualization, logging and application code. Pair it with a dedicated real-time controller for motors, encoders and safety-sensitive I/O so each layer has a clear job.
- 2.4 GHz quad-core 64-bit Cortex-A76 CPU
- 8 GB LPDDR4X-4267 memory for measured multi-process workloads
- Current Raspberry Pi OS Trixie and legacy Bookworm support Raspberry Pi 5
HIGH-BANDWIDTH I/O
Choose the interface path before selecting the peripheral.
Two four-lane MIPI ports, PCIe 2.0 ×1, USB 3.0 and Gigabit Ethernet make the board flexible for cameras, displays, storage and networked development. NVMe needs a separate compatible M.2 HAT or adapter, and every MIPI/GPIO connection needs its matched cable and software configuration. The illustration is a connection reference: any cable and microSD card shown are not included.
- 2 × 4-lane MIPI camera/display transceivers
- microSD SDR104 and PCIe 2.0 ×1 expansion
- 2 × USB 3.0 at simultaneous 5 Gbps plus Gigabit Ethernet
POWER AND THERMAL
Give the finished robot a verified 5 V / 5 A path.
A high-quality 5 V / 5 A USB-C supply with PD support is the recommended basis for the full peripheral budget. A 5 V / 3 A source restricts downstream USB current, and sustained compute needs active cooling. Test the real battery, wiring, controller and sensor load in the final enclosure. Cables and microSD media in the reference image are separate accessories.
- Recommended input: USB-C 5 V / 5 A with Power Delivery support
- 5 V / 3 A operation limits the downstream USB peripheral budget to 600 mA
- Active cooling is recommended for sustained mapping, vision, compilation or logging
FORM FACTOR
Fit the board from the mechanical reference, then verify the physical sample.
The board footprint is 85 × 58 mm with four Ø2.7 mm reference mounting holes. Use the drawing for placement planning, but use a physical board and approved mechanical data for production fixtures because manufacturing tolerances and component representation can change.
- 85 × 58 mm board footprint
- 4 × Ø2.7 mm reference mounting holes
- Keep cable bend radius, cooling airflow and connector access clear

Overview
The Linux and ROS 2 host — not the motor controller
Raspberry Pi 5 Model B with 8 GB of LPDDR4X memory is the computer layer for a robot: it runs Linux, ROS 2 nodes, networking, logging, visualization and the applications that coordinate sensors and actuators. A 2.4 GHz quad-core 64-bit Arm Cortex-A76 CPU gives it substantially more headroom than earlier Raspberry Pi generations, but deterministic motor, encoder and safety I/O should still live on a dedicated real-time controller.
Treat 8 GB as capacity for a measured workload, not a promise that every AI model will run locally. Camera resolution, inference model, storage speed, recording rate, thermal design and the rest of the robot determine the real result.
I/O you can plan a robot around
The board offers two four-lane MIPI camera/display transceivers, a PCIe 2.0 ×1 FFC interface, two USB 3.0 ports that can operate simultaneously at 5 Gbps, two USB 2.0 ports, Gigabit Ethernet, dual-band 802.11ac Wi-Fi and Bluetooth 5.0 / BLE. It also has dual micro-HDMI display outputs, a standard 40-pin GPIO header, RTC battery connector, UART debug connector and PWM-fan connector.
PCIe is an exposed board interface rather than an M.2 socket: NVMe storage needs a compatible M.2 HAT or adapter. Likewise, MIPI and GPIO connections need the correct cable, pinout, voltage and software support. Do not connect motors, high-current loads or unknown-voltage signals directly to the board.
Power and cooling are part of the product choice
For the full peripheral budget, use a high-quality USB-C 5 V / 5 A supply with Power Delivery support. A 5 V / 3 A supply may boot the board, but it limits the downstream USB peripheral budget to 600 mA; it is not the preferred choice for a sensor-rich robot. Plan the supply, fuse, wiring, controller link and peak USB load together.
Raspberry Pi specifies a 0–70 °C operating temperature range. For sustained mapping, vision, compilation or logging, fit active cooling and test the temperature in the final enclosure rather than on an open bench. Current Raspberry Pi OS Trixie and legacy Bookworm releases support Raspberry Pi 5; older Raspberry Pi OS releases do not.
What this SKU includes
COG-RPI5-8GB is the 8 GB bare board only. It does not include a USB-C power supply, active cooler, microSD card, SSD/HAT, case, HDMI/MIPI cables, Ethernet cable or robot mounting hardware. The integration reference image illustrates compatible connections only; the cables and microSD card pictured are not included.
Before autonomous operation, validate the boot image, supply voltage, cooling, storage, controller communication, USB/MIPI devices and cable restraint. Build up from the host and controller link to individual sensors, then verify motion with the robot safely supported.

Frequently asked questions
Is this a complete Raspberry Pi kit?
No. COG-RPI5-8GB is one Raspberry Pi 5 Model B bare board with 8 GB memory. Power supply, active cooler, storage, case, cables, HATs, peripherals and mounting hardware are separate.
Is the 8 GB memory upgradeable?
No. The LPDDR4X memory is soldered to the board. This SKU is the 8 GB configuration; choose the memory size before purchase.
Can Raspberry Pi 5 directly drive motors or high-current loads?
No. It is the Linux and application host, not a motor driver or real-time controller. Use a dedicated controller and appropriate power stage for motors, encoders and safety-critical I/O.
What power supply should I use?
Use a high-quality USB-C 5 V / 5 A supply with Power Delivery support for the full peripheral budget. A 5 V / 3 A source can restrict downstream USB current to 600 mA, so validate the whole robot rather than relying on a phone charger.
Do I need active cooling?
It is strongly recommended for sustained mapping, vision, compiling, logging or other continuous workloads. Check temperature in the finished case because airflow and ambient conditions matter.
Can I use an NVMe SSD?
Yes, through the board's PCIe 2.0 ×1 FFC interface with a compatible M.2 HAT or adapter. The SSD and adapter are not included, and cable/firmware compatibility must be checked.
Which Raspberry Pi OS releases support it?
Current Raspberry Pi OS Trixie and legacy Bookworm support Raspberry Pi 5. Releases older than Bookworm do not. For ROS 2, select a supported 64-bit base image and verify your chosen distribution with its upstream support matrix.
What should I verify before autonomous operation?
Verify boot media, supply voltage, cooling, controller link, USB/MIPI devices, network and cable restraint. Test motion only after the host-controller-sensor system is stable and the robot is safely supported.
