LoRa is a long range, low power wireless platform that is being used by a lot of Internet of Things (IoT) products. Using LoRa and LoRaWAN, devices can communicate across the world using the internet, using various decentralised networks such as The Things Network or Helium. Since, PINE64 believes in openness, the LoRa gateway can connect to any network, per the developer implementation. If Helium Spots open up for PINE64 gateway and developers have implemented the hook for Helium, then this is good thing. The PINE64 LoRa gateway also open connect to The Things Network if developers implement support. The choice is yours!
The gateway will be available in two variants - indoor and outdoor. All that is known about the outdoor unit is that it will have "an aluminum, rugged and water resistant case". The indoor unit consists of a PINE A64-LTS, fitted with a purpose built hat (adapter) which uses a LoRa module by RakWireless. The chipset used is the SX1302, and the module via the SPI interface. There are two external connections on the enclosure for the GPS and loRa antenna.
- GPS is connected to UART2 on the A64 board
- SX1302 on SPI0
|RAK2287 module||PI-2 connector||PINE A64-LTS|
|SX1302 SPI||Pin 19 = MOSI / PC0
Pin 21 = MISO/PC1
Pin23 = CLK/PC2
Pin24 = CS/PC3
|SX1302 RESET||Pin 11 = GPIO17/PC7||GPIO71 (/sys/class/gpio/gpio71)|
|GPS UART||Pin 8 = TX/
Pin 10 = RX
|GPS RESET||Pin 33 = GPIO13/PC5||GPIO69 (/sys/class/gpio/gpio69)|
|GPS Standby||Pin 35 = GPIO19/PC9||GPIO73 (/sys/class/gpio/gpio73)|
Operating System Options (Pinedio Gateway)
Pinedio Gateway carries the A64-LTS board. Based on ram specifications SOPINE images are also compatible.
Gateway is based on the pine64 A64-LTS, and the current Armbian_sopine image download options can be found here: https://www.armbian.com/sopine-a64/
(Previous issues in DTS have been fixed by Armbian developers and Armbian_sopine_21.05.1 is confirmed to boot).
Armbian Official Website: https://www.armbian.com
Download current Dietpi image (for Pinedio/SOPINE/LTS) here: https://mega.nz/file/7VpmAQ6S#CxOpSHBHgFkynXIOKVQEQk8864-DLsNnFtbpCH6PU6o
Dietpi is a lightweight SOPINE/A64-LTS image using Armbian as pre-image (Debian based). Carrying a large array of options, Dietpi includes SBC hardware configurations available inside ncurses menu interface (ssh/terminal accessible).
In addition to being a full on Debian based Linux system, a variety of servers and services can be added on demand.
dietpi-launcher: access all dietpi tools/menus
dietpi-software: select from numerous optimized servers/services to install
dietpi-config: feature rich configuration tool
dietpi-autostart: choose software to run after boot
dietpi-update: update/upgrade system
The entire list of software available for installation (inside dietpi-software) can be found here: https://dietpi.com/docs/software/
Steps To Enable spidev0.0 (rakwireless concentrator device):
As Dietpi strips down the system to a minimum level (deleting much of original Armbian commands), we can install armbian-config command by issuing:
sudo apt install armbian-config
Inside armbian-config -> system -> Bootenv (edit boot environment), enter the following 2 lines (to create spidev0.0):
Save this. Reboot (optionally hand edit /boot/armbianEnv.txt to add the 2 lines). After rebooting you should see a new device /dev/spidev0.0. This will be the concentrator device for gateway related setup.

There are several end-node units planned:
- loRa back case for the PinePhone
- standalone USB dongle-type end-node adapter
- PineTab adapter
- as well as a SPI module (which can also be configured as a USB LoRa dongle)
- a LoRa stick powered by a single 18650 battery (using the BL602, and can be fitted with GPS, an low-power OLED panel and additional sensors)
All the end-nodes use the SX1262 chip.
