## Introduction / Main Floor: PicoCluster Claw: A Localized AI Agent Device with Monthly Electricity Cost Under $2

This article introduces the PicoCluster Claw project, a localized AI agent device built on Raspberry Pi 5 and NVIDIA Jetson Orin Nano. It runs OpenClaw and Ollama to enable fully private LLM inference, with an overall power consumption of only about 15 watts.

## Project Overview

In today's era of increasingly centralized cloud computing and AI services, data privacy and long-term subscription costs have become key concerns for many users. The PicoCluster Claw project offers a refreshing solution—a fully localized, low-power, self-hosted AI agent device with a monthly electricity cost of less than $2.

This device consists of two core components:

- **clusterclaw (Raspberry Pi 5, 8GB)**：Responsible for web interface, agent orchestration, and system management
- **clustercrush (Jetson Orin Nano Super, 8GB)**：Responsible for local large language model inference

Together, they form a private, always-on, low-energy personal AI infrastructure.

## clusterclaw (RPi5 Node)

The Raspberry Pi5 acts as the system's "brain" and runs the following services:

- **Portal (Port 80)**：Unified entry page for PicoCluster Claw
- **ThreadWeaver (Port 5173)**：Chat interaction interface
- **OpenClaw Gateway (Port 18789)**：Agent gateway service
- **Caddy HTTPS Proxy (Port 18790)**：Secure web access
- **Blinkt! LED Status Indicator**：Visual system status

## clustercrush (Orin Nano Node)

The Jetson Orin Nano Super serves as the "computing engine" and focuses on AI inference:

- **Ollama (Port 11434)**：Local LLM inference engine
- **9 pre-installed models**：Covering general dialogue, reasoning, code, vision, and other capabilities
- **CUDA / cuDNN / TensorRT**：Complete NVIDIA AI acceleration stack
- **OpenAI-compatible API**：Facilitates migration of existing applications

## Power Consumption and Cost

The power consumption performance of the entire system is impressive:

| Scenario | Power Consumption | Monthly Cost | Annual Cost |
|----------|-------------------|--------------|-------------|
| Idle |14W |$1.61 |$19.62 |
| Typical Load |20W |$2.30 |$28.03 |
| 90% Idle Mix |15W |$1.73 |$21.02 |

Based on current electricity prices, the annual operating cost is only about $21, which is far lower than the monthly fee of most cloud services.

## Pre-installed Model Lineup

The clustercrush node comes pre-installed with 9 large language models, occupying approximately 27GB of NVMe storage:

| Model | Size | Type |
|--------|-------|--------------------------|
| llama3.2:3b |2.0 GB |General Dialogue (Main) |
| llama3.1:8b |4.9 GB |General Dialogue (High Quality) |
| gemma3:4b |3.3 GB |General (Multilingual) |
| phi3.5:3.8b |2.2 GB |Reasoning Specialized |
| deepseek-r1:7b |4.7 GB |Reasoning (Chain of Thought) |
| qwen2.5:3b |1.9 GB |Code/Structured Output |
| starcoder2:3b |1.7 GB |Code Generation |
| llava:7b |4.7 GB |Visual Understanding |
| moondream:1.8b |1.7 GB |Vision (Lightweight) |

Ollama automatically manages model loading and unloading, dynamically allocating GPU memory based on usage needs.

## MCP Agent Toolset

PicoCluster Claw has 5 built-in MCP (Model Context Protocol) servers, providing 28 practical tools for local LLMs:

## LED Control (5 Tools)

Through the Pimoroni Blinkt! LED strip, it enables:

- Set LED color
- Display progress bar
- Pulse animation effect
- Clear display
