It took me awhile to figure out that it is required to install the USB driver for CP201x from here. Suggest to add this info to the documentation.

Wow! Thank you for pointing it out!

You also need to know that if you are using the ST LINK/V2 (20 pin version) you will need connect the following pins V2-Pin-1 to E5-SWO-VCC, V2-Pin-7 to E5-SWO-DIO, V1-Pin-9 to E5-SWO-CLK, V2-Pin-17 to E5-SWO-RST, V2-Pin-8 to E5-SWO-GND. As example, there are other pins you can use for VDD and GND.

There is no possibility to check battery state, correct? I could not find anything in the schematics like a voltage divider or a connection to an ADC pin...

Hello, well, you can use a board with the meter module and connect the battery and the E5 board, it can meter it and send the battery information to the E5

Hi, the wiki of the Lora E5 Dev Board states that external oscillators are used (High Speed External HSE and Low Speed External LSE), but after I ran into issues, I switched to Low Speed Internal, which resolved the problems.
After checking schematics, I could not find any external oscillators.
Are they just not in the schematic (but on the board) or is this a bug?

How do I connect to the helium network with Wio-E5 Development Kit? Is there an example that can explain step by step? For example, Wio-E5 Development is an application that shows when the button on the board is pressed. Or an application that will display the temperature read from the temperature sensor on the Wio-E5 Development board on the helium console.
Where I am helium 868 is covered in Europe. I made all the settings but I could not connect to the helium network. I tried both platforms below and failed.

I did all the steps below.

I learned Device EUI with the AT+ID command from the serial port in Arduino.
I set the key I generated in the Join EUI section on the console to wio-e5 with the “AT+KEY=APPKEY, “your-key” command.
I think I'm making the mistake in the OTAA KEY section. What exactly is OTAA KEY? What is the difference between the key where it says Join EU?

FYI
For those trying to get I2C working and to get the 3v3 and 5v lines working, I2C is on chip2 with SDA on PA15 and SCL on PB15. So if you are using arduino Wire, you need to Wire.setSDA(PA15); Wire.setSCL(PB15);
The Power lines are also controlled behind mosfets so assert (Make High) PA9(3v3) and PB10(5v)
