FPVCycle 1S-2S AIO

This board does not fit all Whoop frames.  Check measurements if you want to use it for a Whoop.

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 FPVCyle 13mm 11,250kv 1S motor but of course you can run whatever you like on it.

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.

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)

Specifications of AIO board:

  • 1S-2S operation (Max recommended motor is 1302.5 6400kv 2S)
  • We will say ~7A FETs but this number isn't important for this class of quad...

  • ESC MCU: EFM8BB21(50MHz)
  • OSD: AT7456E
  • IMU: MPU6000
  • UART1 (used for vtx by default)
  • UART2( used for rx by default, supports SBUS)
  • 2.2-10v operation
  • Very careful PCB design
  • No motor connectors, only solder pads
  • Separate ground and volt pads for vTX, Cam and Rx
  • F4 MCU preloaded with BF 4.1
  • BF Target: FPVCYCLEF401
  • ESC Firmware: BLheli-S Bluejay F-H-70
  • 32.4mm x 32.4mm
  • Mount pattern: 25.5 x 25.5mm w/grommets to make M2 mount
  • Weight: 4.7g plain board
  • 1.1mm thick PCB
  • Jumper for Rx voltage

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.

Just perfect

I really enjoy this fc for 2 or 3 inch 1s or 2s build

A Solderable Tiny Board!

Very slick board with plenty of room to solder on. I walked a friend of mine through building a babytooth as his first soldering project. No issues!

Sexy board

Finally a micro AIO with motor tabs that actually have space between them.

like it a lot

Two niggles: The holes for the battery leads could be a bit larger. Maybe 0.2mm more so an AWG18 will fit better? And I had to break out an 80 watt soldering iron to do the ground connections of the vtx, camera and receiver (thermals?).

After the original version blew its 5v rail, this one has been a worthy successor! Feels like it actually flies better than the old one right out of the box on the stock tune. Super nice!
