FPVCycle F4 1-2S 7A AIO Flight Controller


FPVCycle F4 1-2S 7A AIO Flight Controller

NOTE:  If flashing this board, DO NOT PLUG BATTERY IN WHILE FLASHING!! The ESC's will burn.  In general it's risky flashing small boards. They don't flash well and often burn.

This board was specifically designed to provide ease of use, reliability and performance for whoop and BabyTooth style 1S and now 2S builds with small motors of 1302.5 size and below.  Because solder pads are notably more efficient at conducting amps, we’ve ditched the connectors entirely.  You’re going to appreciate how large and accessible these solder pads are but this is still a tiny whoop board so you’re still going to need to be pretty careful soldering.  There are also separate volt and ground pads for both the Vtx and the camera so you don’t need to double up wires onto one pad.  Otherwise, the PCB on this guy has been specifically designed to handle the amperage needed for higher performance.  The FET's are usually the limiting factor but on these tiny boards, the PCB is often more important.  This board is specifically designed for the FPVCycle 13mm 11,400kv 1S motor but of course you can run whatever you like on it.



We've been working on this board for over three years now.  In doing so, we've partly discovered why 1S boards are so unreliable.  Getting this thing right and reliable is exceedingly difficult and we've failed more than once in the past.  After over a dozen prototypes, we've been getting really good QC across order batches.  This latest board is designed to handle 2S as well but not huge motors.  Small motor 2S.  No more than ~1302.5 6400kv)
