The use of the product in Germany and most EU neighbouring countries, both the frequency of use (purpose of use allowed due to - (not the LoRa Wireless to be confused) in connection with the transmission power in the respective Frequency applicable regulations not 9.2018) is approved (. The product is intended for distribution outside the EU (Export). We do not stock this item. When ordering, expect a delivery time of 6-10 business days.

Software / GCS support:

The software solution is an Open Source development called "SiK". It has been re-implemented to the new processor architecture, the 32-Bit ARM processor core available. A boot loader and an interface to the further development and on-the-spot Upgrade of the Modem Firmware via the serial interface.

Most of the parameters via AT commands configurable, for example, baud rate (air / Uart), frequency band, power levels.
The built-in support for the configuration of the radio equipment RFD900/RFD868 is supported by APM Planner/ Mission Planner.
The default settings are 57600 Baud, N, 8, 1 and 64 k-air data rate.
