AI agents on a $5 chip — OpenClaw for embedded.
PycoClaw turns an ESP32 into a full conversational agent that plans, remembers, and acts on the physical world — running entirely on-device. Power budget is milliwatts, not watts; hardware cost is dollars, not hundreds.
The agent core is PFC — a MicroPython runtime that tracks OpenClaw feature-for-feature on a microcontroller.
- 🧠 Hybrid memory — TF-IDF keyword search fused with vector embeddings, on-device
- 💬 Multi-channel chat — Telegram, Scripto Studio (Discord in progress)
- 🔧 Tool loop — file I/O, exec, web, sensors, image gen, cron, MCP client, Google Sheets, MQTT
- 🧩 Dynamic skills — Python ScriptOs loaded at runtime from ScriptoHub
- ⏰ Cron + heartbeats — proactive scheduled wake-ups via isolated agent turns
- 🧬 Subagents — full spawn/steer/reap lifecycle for delegated tasks
- 📡 OTA updates — via Scripto Studio
- 🔋 Battery operation — last-gasp flash saves
- ⚡ Real-world control — CAN / I²C / SPI / GPIO / USB / LVGL display
- Get hardware — ESP32-S3 or P4 with ≥8MB flash + ≥4MB PSRAM (~$5)
- Install firmware — pycoclaw.com/install — one-click browser flasher
- Manage device — Scripto Studio PWA (chat panel, file editor, config)

The MCU-class agent field has three serious entries. (Linux/Docker-hosted agents are a different class.)
| PycoClaw / PFC | ESP-Claw | MimiClaw | |
|---|---|---|---|
| Vendor | jetpax (independent) | Espressif (chip vendor) | memovai |
| Language | MicroPython + Python skills | C/ESP-IDF + Lua skills | C/ESP-IDF |
| Runs on | Any MCU running MicroPython ≥ 8MB/4MB PSRAM | Espressif only | ESP32-S3 only |
| OpenClaw compat | Full-parity port (agent loop, sessions, cron, subagents, memory, skills) | Inspired by | Inspired by |
| Memory | Hybrid TF-IDF + Gemini vectors | 5 structured types, summary-tag recall | MEMORY.md |
| Subagents | ✅ | ❌ | ❌ |
| LLM-bypass triggers | ✅ Script cron jobs (direct MicroPython at tick), system-event annotations, autostart background tasks | ✅ Lua rules via run_script |
|
| Inbound-event rules | ✅ User-editable router_rules.json — 6 actions, 5 session policies, hot-reload |
✅ Equivalent | ❌ |
| Provider compatibility | ✅ OpenAI-spec + tolerant tool-arg coercion (GLM/Qwen/Moonshot quirks) | ✅ openai_compatible + qwen profiles | OpenAI only |
| MCP Client | ✅ | ✅ | ❌ |
