Hi All

I just purchased a NanoVNA-H4 from a China seller via Lazada.sg in Singapore.
Can I get help to confirm if this is the original made by Hugen or a clone? It came pre-loaded with Hugen's latest firmware version of 21 Feb 2020.

Wow, you already have the SD-Card reader populated! The black box and that
SD card reader strongly suggests an authentic one, of the latest batch.

This version is produced by me. Thanks to DiSlord for completing the transplantation of microSD. For the newly produced PCB, we have installed a MicroSD card slot and replaced the 2000mAh battery. You can refresh DiSlord's latest firmware and use the microSD card after making holes in the case. I will modify the case and add a 32.768kHz crystal when the next larger version is updated.

Hi Hugen

Many thanks for the confirmation and I am relieved to note that I have bought an original version! The 32.768KHz X'tal is missing on this board although the MicroSD card is installed. Can you please point me to the need for the X'tal? I am away from home and might take several weeks before I can get back to my shack due to the pandemic.

Thank you all for your help on this. Bought the NanoVNA-H last year and now could not resist the temptation to buy the H4 version with more features added!
