      @Yveaux said in serial, Ethernet to MQTT: Of course, but MySensors MQTT gateway runs just as fine when connected over cabled ethernet, as when connected over wifi I do not know that Now on this tool, I do not see much benefit from ethernet to MQTT Still, it is good from serial to MQTT.

      @rozpruwacz said in 3.3v Boost Converter with Pass-Through: Hi, I just came across this project and I like the idea of pass trough very much I have a question, why did You use the LTC3525D part instead of MCP1640C which You already used in other boost converter projects ? MCP1640C is 5 times cheaper than LTC3525D and they are quite similar. I just now revised the board to expose the Enable pin, so now you can do a pass-through if you wish. I also made it more compact and gave it a ground-plane on the back. https://www.openhardware.io/view/279 Enjoy!

      Right you are. Live and learn (even at 81), and I even learned a new word -'vias.' Thanks.

      @Marcel-StΓΆr Sorry, I don't know. Maybe try the datasheet.

      @acb Hi @acb and others, regarding "Do you know if there is a version of this board that is pad-compatible with the C-versions of these HopeRF RFM69s before I go searching? (Since I believe the C-versions are also pad-compatible with the RFM95s…)" - did you find any alternative? I'm in the same boat looking for an adapter from NRF24 to the footprint of RFM69*C = RFM95/96. Thanks, Joost

      @soward I use some sort of no-name 10 uH 12mm (I know, stupidly big) shielded inductor from AliExpress. Looks a lot like these, fairly bulky and heavy: http://m2.uxcell.com/photo_new/20140506/c/ux_a14050600ux0992_ux_c.jpg Haven't done more than go over it with the continuity tester to see that it didn't have some sort of rudimentary inside damage. I also tested the capacitors, they were close enough to 10 uF but I did some surprising minor variation that can't be blamed on the DMM. Random Ebay caps are probably not a good idea if you need spot on values. But they did seem to work.
