I have some recent experience that might be relevant.
I bought a number of E22-900T30DC and E22-90022DC from Cojxu Official Store on Aliexpress. The modules seem to communicate and function correctly (quite good range).
I was interested in reverse-engineering the SPI between the MCU and the SX1262 LoRa chip. When I have removed the metal shield from one of each, they had a single ASR-6505 LoRa chip (which includes an integrated general MCU, so no stand-alone MCU as I expected). This is not a genuine Semtech chip as Ebyte claim on their website and manual. Possibly ASR are licenced by Semtech – but Ebyte state they use actual Semtech, which is not the case in these modules. So I am guessing they are fakes, not made by ebyte.
I bought a couple of E32-433T30D 1B from CDSENET Official Store also – these had separate MCU / LoRa chip, but the LoRa chip had all markings removed – so probably not genuine Semtech either.
My next module purchase will be from CDEbyte, Ebyte’s actual shop on Aliexpress – hopefully they will be the genuine article.
