Handheld Digital Spectrum Analyzer RF Explorer 915 Mhz - €53,40

Nice Topic!
Just my 2 cents (well actually $ 3.60): here a nice small ESP2866 “proto” board if you want to create an ESP8266 + RFM95 node . Anyone cares to create an RFM95 adapter plate for it? (probably I should call it “base plate”?)
A very minimal description is found over here . and some more: [1] , [2] , [3] , [4]
Oh and by the way: the result will not be CE certified

Hey Batilan,
Have a couple of those. Work great with rfm95 and was thinking to make a shield for it (same as the ttl board).
Probably start at it this weekend.

little node antenna
*** update**
that little node antenna is not very well matched @ 868.1 Mhz ( VSWR 4.42:1 ! )
so NOT recommended for long range
this one is much better (1.158:1)

solves your shielding problems
and you can solder it
small solder on antenna:
just 99 cents for any freq you might need… looks better then just a piece of wire

( I’ve used one with a transparent top for a balcony wifi temp sensor )
and I ordered some of these (black/grey) ‘node’ boxes
Feature:1.Every product has a unique Manufacturing Part Number label on the inner package that proves it has been qualified,which include Part Number,Model Number and inspection date information;2.If you have any questions about the item,please...
antenna on one side and temp sensor on the other ?

I was searching for this kind of enclosure for external gateways, looks excellent and cheap will order some
I’m also thinking adding to my RPI gateway a SI7021 sensor ($3) in the box to monitor enclosure temperature and humidity worth checking humidity is not going into enclosure

Monitoring some environmental factors is a very good idea I think.
@kgbvax
Nice idea I was thinking to monitor into the GW enclosure but it’s easy to add another SI7021 to monitor external temp/hum also!
