Is it possible to extend the range of the CyberBrick system by adding an external antenna?
I dont think thats possible currently.
Based on the wiki info the range is approx. 4m
Just out of curiosity, What would be your usecase for more range?
Controlling a locomotive on my garden railway.
Now this sounds like fun…
Yeah i can see that the 4m might be limiting there.
With some fancy soldering you could Frankenmod a 2.4 GHz antenna to the CyberBrick Core (A11), like Happymodel 2.4g omnidirectional antenna for ELRS EP1 RX IPEX/IPX/U.FL compatible with TBS Tracer – Happymodel
An alternative would be enamel covered copper wire, ca. 31mm in length.
With X-acto would need to cut off the PCB antenna (at least make couple of mm large gap) and scrape a bit of solder mask off from the track coming from the circuitry (antenna signal and ground plane) to be able to solder the antenna coax onto it. Then add a blob of epoxy as a strain relief.
Thanks, might be worth at shot.
