Hi Joachim,

I agree. I think the Red Pitaya team have lost their way and customer service is non-existent. I really can’t see the commercial risk in letting me know the part number of the device they use as a 3.3V regulator. When I get some spare time, I’ll do some more fault finding.

I have the same problem – after usage this product for more than 2 years, my red pitaya stopped working. Between 3v3 and Gnd I see a resistance about 3 ohms. Contact to Red Pitaya Repair Service was not successfull, there was no response yet. In future, I dont’t want waste my money for a product, which is so poorly supportet!

In reply to Peter.

Hi Peter,

Thanks for your suggestion but those diagrams don’t help with the power supply fault I have. All the supplies are grouped in a single block labelled DC-DC converters! I don’t see how the power supply can be that commercially sensitive that they can’t release a device number to a customer with a fault! All I wanted them to do was to identify the location of the chip responsible for the 3.3V line and tell me the part number so I could order a replacement. Although the problem may not be the chip, it is a likely candidate and should be a cheap replacement, so worth trying first.

PS: After I complained again they did offer a 10% discount but I’m not prepared to invest another £300 in a board with such poor support.

Thanks again,

Mike G4WNC
