I'm starting to consider changes for future controller designs. If you have an ESP32 based controller, did you install the TFT screen on it?

Hello guys, some of you may know that I've recently ended up in hospital with a trapped nerve in my spine.
I'm doing okay, but not able to put together some new videos for you.
The last video update was about the current monitor/shunt. I have made great progress on this since then, the firmware is 95% complete, and I've got the controller reading the values over RS485. These values are also shown on the web interface and on the TFT screen.
Given my back issue progress is very slow at the moment, but I'm hopefully on the mend and then I can show you what the current monitor does. I know a lot of people are looking forward to that.
Stu.

I've had a few people contact me about V4.40 orders they have placed with JLCPCB.
In production JLC are sometimes swapping part D2 around (rotating it).
If you have ordered from JLCPCB, please check any boards you have had made.
The D2 part should be like in the picture, with the "stripe" towards the right handside of the board, near the "+" sign.
Definitely check before applying power to the module, as an incorrectly orientated diode will cause a dead short across the terminals, probably leading to the fuse going, or something melting!!
There is also a GitHub issue open for more information.
github.com/stuartpittaway/diyBMSv4/issues/73
If you do have boards which are incorrectly built, you have two options:
1. Remove D2 completely (unsolder it), this also means you lose the "voltage spike" protection this part provides
2. Unsolder D2 and rotate it, and re-solder it (recommended)
The part is quite large, so not difficult to unsolder with a normal iron.
