**update 2:**
Meanwhile, we extensively tested the new charging IC - module delivered by TI. And: it worked according to datasheet specs, as it should do! Great! It's not a chip, it's a complete little,intelligent charging computer.

Now it also works without LiPo, only using USB - C energy feeding. Especially it recognices also deeply discharged and protected LiPo's, that has been a little problem before, while testing.
Next: optimizing reach with new fractus antenna, rebranded as **[ignion](https://ignion.io/)** now, while defining optimal additionals components, e.g. SMD coil.

**update 1:**

Today we succeded in finishing**revision D** of our low power LoRaWAN based microtracker, called cattracker. But this will be much more than a pure cattracker.

## Tataa, and here is our little surprise:

This new world class product of german engineering ingenuity will also include a **BOSCH BMA400 3D-accelerometer**, **high precision thermometer** and a **very low energy step counter**, by default of course, with no additional costs.
Thus a lot of very new usecases will become reality soon, e.g. some applications in the medical field (wearing sensors) by using activity parameters to control clinical [processes](http://caretracer.de/):

This picture shows, that BMA400 has been recognized successfully by SoC.

Just to get some impression, we show you here the back side of PCB:

Now, we are measuring radio range..... soon to come here.
