I’m not sure what caused the failure. Maybe static electricity when I handled the board, maybe I pushed too hard when I inserted it in the case (but I didn’t push hard).
I searched if the screen could be replaced but found no useful info. It is glued to the board.
Maybe I’ll repurpose the board for something that does not need a display.
Got the latest GPS #ESP32 logger boards and they seem to work well. The one in the car shuts down to deep sleep when car off, waking every hour to get a fix. I think my work here is done :-)
I've had my eye on this #ESP32 kit from #LilyGo for a while now but haven't purchased it because the device didn't have a back cover. Well, now they're selling them with a full shell!
It's basically an ESP32 #FlipperZero at this point and I am here for it. (Yes, I know it doesn't have all the Flipper's hardware features)
A #LoRa devboard with #ESP32 for #169MHz - does it exist? It seems that LoRa is allowed on 169MHz in EU with the usual caveats so it should exist, but I can’t find it.
PacketIRC: A lightweight IRC terminal server that will let radio-based clients participate on IRC without the usual flood of silliness by @VY1JN https://github.com/juniberry/PacketIRC
As the server PSUs feature #SMBus connectivity, we planned to display some metadata on an OLED.
I soldered up a small perfboard with a buck converter, #ESP32 and a few connectors.
The ESP32 only communicates with the low-side PSU, as I didn't want to implement isolated I²C.
But I noticed that the values coming from the PSU were pretty hit & miss anyways. Especially during light loads.
So I simply used the values that matched the actual values closest and doubled them.
The new USB data logger (thanks for inspiration @neil) #PCB has #ESP32 S3-MINI, SD card slot, LiPo charger and connector, USB-C with serial data, accelerometer, row of RGB LEDs (idea is to show how many satellites in view), and a big cap (learned my lesson). Connects to second PCB that has the GPS module itself.
