# Raspberry Pi
Run a persistent, always-on OpenClaw Gateway on a Raspberry Pi. Since the Pi is just the gateway (models run in the cloud via API), even a modest Pi handles the workload well.
## Prerequisites
- Raspberry Pi 4 or 5 with 2 GB+ RAM (4 GB recommended)
- MicroSD card (16 GB+) or USB SSD (better performance)
- Official Pi power supply
- Network connection (Ethernet or WiFi)
- 64-bit Raspberry Pi OS (required -- do not use 32-bit)
- About 30 minutes
## Setup
<Steps>
<Step title="Flash the OS">
Use **Raspberry Pi OS Lite (64-bit)** -- no desktop needed for a headless server.
1. Download [Raspberry Pi Imager](https://www.raspberrypi.com/software/).
2. Choose OS: **Raspberry Pi OS Lite (64-bit)**.
3. In the settings dialog, pre-configure:
- Hostname: `gateway-host`
- Enable SSH
- Set username and password
- Configure WiFi (if not using Ethernet)
4. Flash to your SD card or USB drive, insert it, and boot the Pi.
Open the printed URL in your local browser. For always-on remote access, see [Tailscale integration](/gateway/tailscale).

## Performance tips
**Use a USB SSD** -- SD cards are slow and wear out. A USB SSD dramatically improves performance. See the [Pi USB boot guide](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#usb-mass-storage-boot).
**Enable module compile cache** -- Speeds up repeated CLI invocations on lower-power Pi hosts:
**Reduce memory usage** -- For headless setups, free GPU memory and disable unused services:
```bash
echo 'gpu_mem=16' | sudo tee -a /boot/config.txt
sudo systemctl disable bluetooth
```
## Troubleshooting
**Out of memory** -- Verify swap is active with `free -h`. Disable unused services (`sudo systemctl disable cups bluetooth avahi-daemon`). Use API-based models only.
**Slow performance** -- Use a USB SSD instead of an SD card. Check for CPU throttling with `vcgencmd get_throttled` (should return `0x0`).
**Service will not start** -- Check logs with `journalctl --user -u openclaw-gateway.service --no-pager -n 100` and run `openclaw doctor --non-interactive`. If this is a headless Pi, also verify lingering is enabled: `sudo loginctl enable-linger "$(whoami)"`.
**ARM binary issues** -- If a skill fails with "exec format error", check whether the binary has an ARM64 build. Verify architecture with `uname -m` (should show `aarch64`).
**WiFi drops** -- Disable WiFi power management: `sudo iwconfig wlan0 power off`.
