      @bearer said in 12V on the 5V rail:

      but should be compatible with AP7361C-33ER-13

      @Haggan90 just clicked in my head the AP7361C doesn't specify if the tab is connected to v-out or gnd or anything at all; so I can't say for sure if it works.

      TC2117-3.3VDBTR is the full partno from the 1.03 schematic.

        IS this the correct one?

          has the same manufacturer part number as on the schematic at least, so thats about as sure as I can get.

          "Tillverkarens artikelnummer TC2117-3.3VDBTR"

          (the key to decoding the part numbers are usually towards the end of the datasheets, helps decode the various letters and numbers)

            @bearer Hi!

            I have now changed the U2 and I can connect to the board via USB 😃
            It seems like maybe the WiFi module is broken, but is there any way I can check that over YAT?

              just follow the getting started guide to set up wifi again, if it responds to M552 and connects you're good.

                @bearer ok!
                The blue LED does not light up on start, is that a bad thing?

                  Ok, it seems like I can't get the Wifi module into idle mode.
                  Also, I do belive it get's a bit warm, not hot but warm.

                    @Haggan90 try deleting all saved wifi networks with M588 S"*" (That is, using an asterix for the network name), then re-adding it with M587. For example, M587 S"networkname" P"password".

                        @Phaedrux The SD-Card seems to be fine.
                        Do I need a hot air desoldering station to change the Wifi Module? And, what would I need to do after I've changed it?
                        This is what I get when sending M21.

                          A good preheating and some quickchip or similar 138C-ish melting point solder might to the trick; but most likely "yes".

                          edit: oh, and after all you need to do is run M997 S1, presuming the wifi firmware file is in the /sys folder on the SD card.

                            @bearer Thank you! I will see what I come up with to desolder it 😃
                            Is there any special version of the ESP-12S Wifi Module I need?

                              Thats about as specific as you can get, but no, any ESP-12 ought work, the 12S has all the right certifications on it which is important for Duet3d selling them, not so much for you. I.e. you could use a 12E or F if easier to obtain (or pretty much any other ESP with the same footprint)

                              (the ESP-07S is an official option if you want external antenna, just make sure to never run it without antenna attached to avoid damage to the rf tx)

                                I just ordered a ESP-07S as I have a bunch of these antennas laying around, hoping for a bit better range on the WiFi then 😃

                                  Manage to desolder it using a regular soldering iron, now I just need the new chip!

                                        Unfortunalty is seems like the Duex2 took a hit as well, as I can't get the steppers working there.
                                        Nothing get's hot on the board.
                                        Any idea what could have broke on the Duex2?

                                          Does M115 report that there is a DueX connected? If not then the SX1509B chip has probably failed.

                                            And where can I find it on the DUEX2? 😃
