This board was specifically designed to provide ease of use, reliability and performance for whoop and BabyTooth style 1S builds. Because solder pads are notably more efficient and effective, we’ve ditched the connectors entirely. You’re going to appreciate how large, clearly marked 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. Around back you’ll find a jumper for the voltage you would like to set your Rx to and if you’re planning on going with Sbus or CRSF (inverted or un-inverted). Otherwise, the FET’s on this guy are specifically designed to handle motors around the 1202.5 range in ~10,000-12,000kv like our FPVCyle 1202.5 11,500kv.
Before designing this board, we heavily weighed whether we wanted to bake in a receiver. Usually boards with built in receivers have poor signal performance at best. We spent months talking to TBS about how to build Crossfire into a board. After numerous possible methods, both TBS and us gave up and decided to separate the boards because it just wasn’t reasonable. Crossfire receivers are quite labor intensive to make. Each and every Rx goes through rigorous testing before it gets packaged and sent out. It just was not reasonable to do that much work on a board that has so much else going on. The weight savings were just about negligible at less than 0.25g. So we did the next best thing. A seat for the Crossfire Rx….however we do not recommend using servo pins to connect the two boards. Pins break and in this case, if you tried to use pins, you couldn’t even mount the board onto screws because it’s just too small of a board. Short wires are recommended in order to resist pin or board fracture from impacts. This is how both the Crossfire and Unify Pro32 Nano are attached as seen in the pictures.
NOTE: You must solder the jumpers on the back side of the board to select Rx voltage and Sbus or CRSF (inverted or uninverted) control signal. The Rx will NOT be powered or signal read without soldering these jumpers.
All boards come with an XT30 pigtail and the rubber inserts. The combo packs come with either crossfire or crossfire and the Unify Pro32 Nano pre-installed as well as the MiniMortal T V1 antenna. There’s supposed to be two bits of heat shrink in there as well but the weather has been a bit warm lately so we believe the shrink may be pre-shrunk by the time you get it. We apologize for this. It’s kind of something we can’t control if it happens.
Specs of AIO board:
- 1S. This is a 1S board. DO NOT RUN 2S!

Really well thought out flight controller making it really easy to setup toothpick builds! Planning on ordering more as soon as more are available.
If you want a premo FC, go with this one. It just does not compare to other 1s boards for toothpicks. Works perfect
This is a great AIO for the Baby Tooth. The FPV Cycle motors run super smooth, flight characteristics are excellent, and it flies great on the recommended BF 4.1 settings. Pair it with the TBS duo and everything fits neatly under the Bee Brain Canopy.
I must say the solder pads on this AIO are a dream to work with. Large motor pads, normal sized UART pads, and the battery pads are significantly easier to solder compared to many other AIOs, especially the Mamba F411 IMHO.
The first FC arrived did not recognize
ESC #3 in blheli. The second replacement FC that arrived popped an ESC and did not recognize gyro/Accelerometer as soon as it was powered up on bench.
The third replacement FC smoked 3 ESCs on the bench while connected to Betaflight. My money was refunded.
This is THE board to be using for your 1s builds. With the receiver and VTX already installed, and good sized solder pads for the motors, this thing is a breeze to work with.
