We have spent several months working with Angle of Arrival (AoA). As a result we found reasons to redesign our latest generation of LPS boards a bit. This new board combines all our knowledge so far:

In short this is what LPS^2 can offer:

* ARM Cortex M4F.

* UWB.

* WiFi if needed (can be soldered in as a ESP12-E/F module).

* Can act as a RFID tag.

* Accelerometer/gyro/compass/altimeter/thermometer.

* TCXO or ordinary XTAL.

* Clock and sync handling/distribution for TDoA/AoA.

* Can charge a LiPo either from USB or a small solar panel.

* Can be controlled and reprogrammed via USB, BLE and WiFi.

* Extra flash for data storage.

* Size: 34x52 mm.

It will very soon be sent to production! :-)

As pointed out earlier this board will not replace any of our other boards, it is rather a complement with the ability to work as a TDoA/AoA anchor.
