What are the UART pins on this board?
This board is from a Helium Hotspot Linxdot ld-1001. I’ve been researching how to possibly gain shell access via UART. However, all the adapters and videos I see for UART to USB shows matching up the RX, TX, GND.
Problem with this board is the UART is labeled next to what appears to be a 3.5mm headphones jack. I’m not saying that’s what it is, just looks like it. Does anyone know of an adapter that would work with this? Or any idea of other methods for getting shell access?
What is going on?
My Ice Berg rose bushes in SoCal are infected with something. I asked ChatGPT a while ago and it suggested it was Chili Thrips, so I went and bought the Bioadvanced Rose and Flower Insect spray and Rose and Flower granules at Home Depot.
It’s been several weeks trimming the affected areas and using both weekly with no improvement. So I figured I’d turn the Reddit experts, what am I doing wrong?
