My DIY low-power 6 SSD NAS based on the Quartz64 ARM board
Sunday, May 29, 2022
Introduction ARM SBCs have been around for a few years now. They were made popular and accessible mostly by the RaspberryPi released in 2012 . I’ve been enjoying building countless projects around these boards : web servers, home-automation, camera recording, IM bots,… A new trend has recently appeared in the SBC world : the PCIe slot! The RaspberryPi 4 Compute Module exposes it via the IO board , and the Pine64 RockPro64 is equipped with a PCIe 4x open-ended slot directly on the board.…

I decided it was time to replace the keyboard. Fortunately, the wiki provides a very detailed replacement procedure . I followed it to the letter and everything went well. I took a few pictures during the operation and have already added them to the wiki page as well.…

A driver for the LoRa backplate for the PinePhone
Thursday, November 25, 2021
In previous articles, I introduced the LoRa blackplate for the Pinephone and I flashed the onboard MCU with an SPI<->I²C bridge firmware . In this post, I’ll write a driver that allows the Pinephone to send ant receive LoRa messages via this LoRa backplate! How to communicate with the SX1262 ? The SX1262 (LoRa radio) is an SPI chip. As the pogo pins only expose and I²C bus, the Pinephone cannot communicate directly with the radio.…

Flashing the LoRa backplate for the PinePhone
Wednesday, November 24, 2021
In the previous article about the LoRa backplate for the PinePhone , I introduced the devices and tried to understand how it was supposed to work (I received the devices with no instructions at all). I made a few assumptions regarding the pinout of the pogo pads and of the wires that were soldered on one of the board by looking at the PCB, at the schematics and at the source code of the bridge (I²C <-> SPI) firmware that is linked on the wiki :…
