  • I’ve now had three fail. I discovered that a 7805 linear regulator has the same pinout and can be soldered into the power pins near the USB port to get the board back in service. I don’t see a post from Sparkfun, however they have confirmed to me that there is an issue and the TPS62133RGTT regulators are blowing up due to a design flaw on this board.

  • Is there a known issue with the regulator failing on these boards? I’ve had two out of five fail after only a few weeks of operation. It appears the TPS62133RGTT step down DC-DC converter has failed on both. They are all powered by commercial switching power supplies from a very well known distributor. I have scoped them and they have clean 12 VDC power well below the 17 V limit.

No public wish lists :(
