Product Brief (PDF) Datasheet(PDF) G.FIT Downloads G.FIT enables technology maintenance with both built-in support for easy wireless updates and the addition of custom tailored features and controls using the G.FIT SDK. G.FIT solves personal device pairing by re-broadcasting ANT+ or BLE heart rate data and works with Bluetooth FTMS (including Control Point) and the ANT+ FE-C Device Profile so that people can record entire workout sessions on their own personal devices. G.FIT makes it easy for non-technical users to pair by using proximity pairing and list pairing features. G.FIT solves pairing and setup difficulties with dual protocol support for both ANT+ and BLE heart rate monitors. G.FIT works around WiFi interference to ensure large groups of 50+ devices can connect concurrently. The G.FIT solution is the result of that evolution, and solves the challenges of group fitness: has evolved individual fitness machines and smart bike trainers to incorporate wireless standards group fitness capabilities. G.FIT Meets the challenges of group fitness G.FIT is exclusively available on modules from Garmin Canada Inc. ![]() Probably this is because cheap hires who don’t understand chip functions can do the data entry for SamacSys.G.FIT is a turnkey dual-protocol ANT/ Bluetooth® low energy technology (BLE) solution for wireless fitness equipment and smart bike trainers, optimized for group and classroom training applications (e.g., leader board applications) with 50+ fitness devices and multiple receivers. This was also easy to correct in the editor. ![]() I know that pins on a symbol are usually arranged/grouped by function, not by position, but for these components (a LED display and a driver chip respectively) along the perimeter is as good as any and less confusing. Also the pins were not assigned sequentially going around the perimeter but in two rows. For example all the pins were of type unspecified, but this was easy to correct. I’ve found that they were a bit lazy with the symbol files. kicad_mod files for the part which you can import into your own library with the Symbol Editor or the Footprint Editor. You can then get a zip file containing ECAD data for various EDA software, Kicad being one. If you can find the part page at LCSC (and make sure it’s the part you bought or will buy), you can download ECAD data provided you sign up with SamacSys (for free). I finally got around to examining some components I bought from LCSC.
