#### Raspberry PI
Raspberry PI support is experimental - see [Nimbus](https://github.com/status-im/nimbus/#raspberry-pi) instructions for how to prepare the Raspberry for building `nim-beacon-chain`.
Raspberry Pi support is experimental.
We recommend you remove any cover or use a fan as the Raspberry Pi will get hot (85°C) and throttle.
* Raspberry PI 3b+ or Raspberry Pi 4b.
* 64gb SD Card (less might work too, but the default recommended 4-8GB will probably be too small)
* [Rasbian Buster Lite](https://www.raspberrypi.org/downloads/raspbian/) - Lite version is enough to get going and will save some disk space!
Assuming you're working with a freshly written image:
```bash
# Start by increasing swap size to 2gb:
sudo vi /etc/dphys-swapfile
# Set CONF_SWAPSIZE=2048
# :wq
sudo reboot
# Install prerequisites
sudo apt-get install git libgflags-dev libsnappy-dev libpcre3-dev
mkdir status
cd status
# Install rocksdb
git clone https://github.com/facebook/rocksdb.git
cd rocksdb
make shared_lib
sudo make install
cd ..
# Raspberry pi doesn't include /usr/local/lib in library search path
# Add it to your profile
echo '# Local compiles (nimbus - rocksdb)' >> ~/.profile
echo 'export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.profile
echo '' >> ~/.profile
# Install Go at least 1.12 (Buster only includes up to 1.11)
# Raspbian is 32-bit, so the package is go1.XX.X.linux-armv6l.tar.gz (and not arm64)
curl -O https://storage.googleapis.com/golang/go1.13.3.linux-armv6l.tar.gz
sudo tar -C /usr/local -xzf go1.13.3.linux-armv6l.tar.gz
echo '# Go install' >> ~/.profile
echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.profile
# Reload the environment variable changes
source ~/.profile
git clone https://github.com/status-im/nim-beacon-chain.git
cd nim-beacon-chain
# Follow instructions above!
```
