Lora version identification

[willie]

Using Meshtastic and there are two possible versions to flash, Ver2 and Ver2.1
My board says V2 but looking at the circuit board layout, it looks like V2.1
Is there a definitive way to tell?
Thanks for any help.

Check on this Pinouts Diagrams with foto of boards by compare SMD components.

one is from this forum

ESP32 LoRa (V2.1) without a component

And how do I know it is"succsessfully" powered on ? I tried to keep holding the PRG button before connecting the microUSB, release the button and then upload with Arduino IDE. The error still happens. I also tried to keep pressing it forever, but after the “Connecting…” timeout the error occurs. I’ve read about connecting a 10uF eletrolytic capacitor between EN and GND, but i didn’t find the EN pin on WIFI LoRa 32(V2.1) Pinout Diagram. [image] Thanks!!!
