Meshtastic Raspberry Pi Zero 2 W based node, with GPS

Meshtastic stationary node:

• Raspberry Pi Zero 2 W (soldered longer gold pins - 17mm; regular are too short)
• Waveshare SX1262 LoRaWAN Node Module Expansion Board ( https://www.waveshare.com/sx1262-lorawan-hat.htm )
• Waveshare 1.44" LCD hat ( https://www.waveshare.com/1.44inch-lcd-hat.htm )
• GPS antenna (like from https://s.click.aliexpress.com/e/_DCeU5lh )
• UFL – SMA female connector ( https://s.click.aliexpress.com/e/_DlYPJT9 )
• Sirio SO 868-915-2 W/Cable antenna ( https://www.sirioantenne.it/en/products/uhf/so-868-915-2 )

### disable swapfile
sudo dphys-swapfile swapoff
sudo dphys-swapfile uninstall
sudo systemctl disable dphys-swapfile
sudo systemctl mask dphys-swapfile


### enable zram
sudo apt-get install zram-tools
### /etc/default/zramswap

ALGO=lz4
### PERCENT= commented out


### force more zswap swap usage
# cat /etc/sysctl.d/99-local.conf
vm.swappiness = 80
vm.page-cluster = 0
