You can get a modern Armbian image for a BPi R1 (also known as Lamobo R1) by doing this: sudo apt install docker.io docker-buildx git clone https://github.com/armbian/build cd build sudo usermod -aG doc...

docs link wiki link I ran Armbian. It was alright. Some notes: Use armbian-config to get more of the hardware exposed Serial will not be exposed as ttyAMA0 or whatever - it’ll just be ttyS0, ttyS1 and so on. Read dmesg and you will see!

This error will show up when you try to update PCB from schematic (for instance, using the F8 key). This usually happens when you copy pieces of schematic between projects - which is kickass and everyone should do more of that! However, if you end up with duplicate reference designators, this error will happen every time you try to sync to PCB, preventing any updates from happening. To fix thi...

Are you looking out for antennas? Need a few uFL-connected marvels for specific frequencies (WiFi/LoRa/4G)? Got five RF modules on your PCB and you’re running out of edges to place them at? Is your Aliexpress-sourced fancy “2.4GHz” patch antenna performing worse than a ESP32 module’s built-in PCB squiggle? Here’s how you can get a bundle of antennas for your devices. The first part of the secr...

Got a Beepy with U2 that’s gone? This post is for you. Here’s how to fix it with a single part from Amazon/Aliexpress, a knife, and a soldering iron - no hot air required. U2 is the 5V boost, TPS61090. It dies, a lot, whether you interact with it or not. There’s a few possible culprits that people talk about. It could be inappropriate (not corresponding to the datasheet) or inappropriately p...
