My Red Pitaya failed recently after about 2 years of occasional use. It’s probably a 3.3V power regulator fault but the Red Pitaya team won’t supply component details and don’t have a repair option! So that’s £250 gone and not even an offer of a discount for a replacement board! As a result, I’ll be steering well clear of anything Red Pitaya in future 🙁

There looks to be deveopment schematics available.

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,

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!

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.
