Any others worth And bootchk designed it using KiCAD - well done! As a side note, in the very early days of the MySensors core team and I) decided that, in the spirit of open source, to abandon commercial / proprietary CAD programs for the MySensors official board designs, hence why SenseBender Micro is in KiCAD and the forthcoming gateway will be too. There is one on Tindie that I've already mentioned (above). So, it's either DIY, or else find some other BQ25504 board that's priced more sensibly. However, TI's eval board for the BQ25504, is a totally insane $99. So, regardless of soldering difficulty, the BQ25504 looks like it's sufficiently better that it's worth pursuing. Why? Well, it turns out a guy in Switzerland has already done more or less the experiment that I was going to do, and this is his conclusion: Is it available in a larger package or pre-soldered onto a breakout board? But at 3x3mm in size, I'm afraid it would be challenging to solder it. Yeah, the BQ25504 does appear to offer nice functionality. ![]() Is it available in a larger package or pre-soldered onto a breakout said: but add cost.įor outdoor a bit easier, and perhaps does not need expensive ic to run etc. for indoor, with all packet exchange we have for a transmission can be critical. ![]() These low input voltage are nice, but it's not a big harvest. Lot of articles about this on internet too. There are also multiple solar charger boards which exist like the adafruit or the lipo rider, more simple but can do the job too etc. I'm designing a board for solar so i've studied a bit alternatives for my usecase.īest is to fit an app, because there are always lot of dilemma and compromise regarding solar panel used, input voltage, effiency not always the same with MPPT, and cost.not so simple, One of the best part i know for this is also the BQ25504. ![]()
