  • OK. An update just in case this might help somebody else. I was eventually able to switch the d0 and d1 "pins" from 3.3V (the default setting of d1=1 and d0=0). I went to 2.5V by setting d0=1 and d1=0 - basically reversing the default settings of the board. And.... it does work - it generates current at 2.5V. :-) But..... to do it I had to work hard to remove the solder bridges on the d0 and d1 pads - and then re-create solder bridges the opposite directions (look at the board and you'll see what I mean). This process was pretty "iffy" for me. It almost did not work and the board was getting pretty nasty looking near the pads by the time I was done. I wish there was an easier way to switch the state of d0 and d1 to change the output voltage - maybe a jumper???? That's my story anyway. Hope it helps somebody.

  • I bought a couple of these looking to have access to the LTC3588 in a breakout fashion. I have found - so far - that the access to the LTC3588 is somewhat limited. Let me start by saying that this board DOES work - but only at 3.3V and for limited configurations.

    Not sure yet what exactly is possible with regard to accessing the LTC3588 pins and features. I took a look at the Eagle files to see where the LTC3588 pins were actually routed on this board.

    The board seems to "hard wire" d0 and d1 to 3.3V using soldered pads - and even though d0 and d1 are accessible, my attempts to use them to select other voltages have not been successful. I have not yet tried removing the solder from the pads - but that might work from the schematic. The board obscures the LTC3588 Vin2 and SW from direct usage and access. The LTC3588 PGOOD pin is re-labeled EN. LTC3588 Vout is combined with LTC3588 SW and an inductor/capacitor to create the board's Vcc.

    Again, this board DOES generate a current at 3.3V when something like a solar panel is correctly connected (using PZ1 and a resistor I found), but it may be limited in terms of other LTC3588 flexible usage.

  • The board seems to "hard wire" d0 and d1 and obscures Vin2 and SW from usage. Vcc looks to be a combined SW and Vout. I posted a full comment with all of my impressions.

  • I was hoping to do the same thing you were trying to do. Not sure yet that it is possible in that the board seems to "hard wire" d0 and d1 and obscures Vin2 and SW from usage. I posted a full comment with all of my impressions.

No public wish lists :(
