There has been massive interest in this since the first GXB20 thread: [[ GXB20 Driver – Homemade Constant Current Programmable XHP50 Single-Cell Boost Driver! ]]. Then came the first GXB17 thread: GXB17 Driver – 17mm 6V 3A / 12V 1.5A Constant Current Programmable Single-Cell Boost Driver which generated interest also. But despite all this interest not a single driver was made from anyone here besides loneoceans, at least to my knowledge. Now here is a new GXB17 with the same teasers as the first…
The good thing that came from those first two GXB threads is that it inspired others like Schoki and Jensen567 to start designing one. So no matter what happens to this new GXB driver, a 17mm boost driver is on the way, designed for usage with already known BLF firmware (which thankfully has nothing to do with arduino).
