@saglettn Is your V2 board some new version (see below)?
I have some questions about (new) Heltec Wifi LoRa 32 ‘V2’ boards:
-
Has a new Heltec Wifi LoRa 32 V2 been recently released that is different from the existing ‘V2’?
(Heltec initially was not using V1 and V2 in the names or on the PCB, which is why I introduced version numbers V1 and V2 for existing Heltec boards earlier this year. Now in the V2 pinout diagram I do see V2 marked on top of the PCB.) -
Is your V2 PCB explicitly marked with a version number?
Is it like the version number shown in the V2 pinout diagram? -
Are there any known differences?
In this post:
@saglettn mentions a ‘new’ pinout for the Heltec V2.
On the pinout I see “V2” marked on the PCB but I see no pinout differences when comparing it to the previous Heltec Wifi LoRa 32 pinout diagram (the one mentioned in the Topic Start). Only the board picture seems to have been updated. DIO0, DIO1 and DIO2 are still not listed in the new pinout so it’s impossible to see if their pinouts/connections have been changed (DIO0 is still called LoRa_IRQ in the V2 diagram). The V2 diagram also contains a sloppy error: the legenda has been moved to the right but ‘Button’ and ‘Touch1’ which belong to GPIO0 have also been moved - incorrectly. So how reliable is the V2 diagram?
In this post:
@Verkehrsrot states DIO1 = 34 and DIO2 = 35.
@saglettn confirms this works. The values for Heltec ‘V1’ and ‘V2’ have been DIO1 = 33 and DIO2 = 32.
Has Heltec changed this on a new version of their boards?
YES, see further below.
