Hi Erange
A few weeks ago a corporate decision was made to discontinue TREK.
EVK1000 however is still available and will be for a while.
TREK is the only product which disccontinued, in contrast to DWM1001 and DWM1000. These modules will hit the shelves again soon.
Due to covid-19 there has been a delay in production of these modules.
Kind regards
Leo
