TEST: Eachine AIOF3: 3g, SPF3, Builtin FrSky D8 w/telemetry, builtin BetaOSD



With the Eachine AIOF3, here is an new ultralight Flight controller based on the powerfull F3 ARM core supporting directly Betaflight (3.0.0 by default), including a buitin FrSky D8 receiver (like the FrDR3) with working telemetry but now also integrate the Betaflight OSD. With betaflight OSD, you can configure everything from the Chrome GUI !!! just great. Cherry on the cake, FET are annouced to handle up to 10A so even compatible with “big” 10mmx20mm coreless brushed motors.


+ 1 x AIOF3
+ 1 x Powerlead cable with microLOSI connector
+ 1 x Foam pad with double tape



A 37mmx29mm board …too large to fit a TinyWhoop/Eachine E010… but more adapted from a 80mm machine


The CC2500 RFchip associated with the FrSky receiver is installed on top. Nearby a ATmega328p to control it but no dedicaced pads to flash a new firmware. For the FrSky version, we have a binding button. You have to hold this button while powering the board via the USB for example. Good news, the receiver firware have been updated to correctly output RSSI & Vbat by telemetry. For the 6-axis stabilization, we have a MPU 6000 from invensense. The OSD processor is a AT7456E. Notice the big cap here for the +5V voltage regulation. It should help to filter out most interefences coming for the FPV connexion

The other side welcomes the main ARM F3 MCU and the strong FET supporting 10A at peak… (probably some ic995 chm2310p chip variant)
It’s just great !!!! In one year, FET were able to handle max 4A… then 6.4A. Now we have 10A models…. It means, bigger/stronger motors can be installed


3g so just 0.4g more than the FrFR3 without OSD.




Here are for example the connexions with the Eachine MC02 but more lighter AIO FPV cam can be used of course as soon the Video pads are found. We can expect bundle TX01+AIOF3 Under 7g.





The AIOF3 is clearly a super board with strong elements: strong FET, strong ARM F3 MCU, builtin FrSky D8 with telemetry, strong OSD and betaflight ready. Probably the best 1S board in the market. What’s a pity there is no way to use it in 2S configuration.


+ 3g
+ Builtin FrSky D8 receiver with working Telemetry
+ Builtin BetaflightOSD
+ F3 processor
+ Compatible Cleanflight/Betaflight
+ Strong 10A FET


– No 2S support

    Great review, thanks. I’m looking at this FC to start to replace some of my Scisky FC builds. My Taranis has the FrSky EU-LBT firmware version. Do you think this FC is compatible with this EU-LBT version?

    • SeByDocKy says:

      Good question … and I don’t know the answer precisely but the firmwware is the one done by Medelic in RCgroups ….I read somewhere some EU onwers were able to bind some Eachne QX’s quad with more or less the same type of board … so it’s not a clue but there is hope that Taranis-EU can bind this FC

  • FaPV says:

    It should be compatible if you disable the EU setting when flashing your taranis but D8 mode (which this is) is disabled by default in the EUlbt firmware. Hope I’m not teaching you to suck eggs with my theoretical guess but I got my QX95 with similar Eachine FC bound to my EUlbt Taranis.

    I bought this FC on bangood to build my very first micro quad !

    My english is not perfect and I have a question about this sentence :
    “Notice the big cap here for the +5V voltage regulation. It should help to filter out most interefences coming for the FPV connexion”

    Does it mean that this FC includes a “booster” from 2.7 to 5V ?
    I’m asking this because the camera I will use needs 5V, and provides a “booster” to solder to be sure to have 5V.
    If I understand correctly and understand the picture, I could connect my cam to the FC without the booster as the FC already provides a “real” 5V.

    Am I right ?

    Thank you

    I can get the RSSI to show up in the osd. Vbat is fine. I also don’t detect any sensors on my QX7. Any idea how to fix this?
