NEWS: Micro Revo F4 FC (<4g, 27x27mm)

A microFC based on F4 board ? yes with this new model: http://www.banggood.com/Micro-Betaflight-3_1_0-Revo-F4-Flight-Controller-2020mm-Built-in-PDB-5V-1A-BEC-p-1125680.html. This new FC integrades super powerfull F4 ARM processor twice faster than F3 ancestor model. With last Betaflight OS, you can ajust Loop time set to 8Khz and main probably even to 16khz for even smoother on the “rail” flights. Notice that with last Betaflight release looptime can be already ajusted to 8khz with F3 processors.

    I have this FC. It flies nice in 8/8 kHz, no complaints about that. However it is not a REVO in BetaFlight – it must be flashed as AIRBOTF4 target. It have some design flaws on board too which are resulting as only one available UART for RX (you can’t connect MinimOSD to it) and LED strip output is nonfunctional. If you wish to have working LED strip, you must solder it directly to MCU pin 15 (PA1 aka A01). I described it in more detail here

      Thanks for the feedback 🙂

      FYI: It is possible to use Micro MinimOSD in quadcopter with this FC in standalone mode. There will be no stick commands available but at least you will have a voltage, timer and analog RSSI (if your RX have analog RSSI output support). Reflash MinimOSD with MW_OSD with NOCONTROLLER option through Arduino IDE. Then configure it from MW_OSD GUI. I have VBat, RSSI and timer working in MinimOSD without problems in this way. Connect battery “+” and RX analog RSSI output to BATT2 and RSSI sensor inputs on MinimOSD board. You should probably tune upper level of RSSI before use – it is straightforward no-brainer task.

      Hey Krotow,

      I have this board. I’ve been trying to get my DSMX receiver to work with it, but am not having much luck. You said in the RCgroups thread that TX1/RX1 are not working so I tried RCIN after RX1. My board came with the REVO image and I initially updated it to the latest release of that. Things seem to work okay, apart from the receiver. Should I flash to AIRBOTF4?

      Thanks in advance!

    Hello, i need an info: can i take 5v from the leds to power the fpv camera and tx video?
    Do I need to modify something?
    Sincerely.

    • SeByDocKy says:

      I am not sure the LED port will be strong enough to power both camera & VTX… If you can use a standalone PDB

    • Krotow says:

      Don’t do that. BEC on this FC is barely able to power MPU, RX and LED strip. Camera and VTX (or AIO camera) must be powered from battery (if camera and VTX can work from voltages above 12V) or through separate BEC with 5V output voltage (for 5V AIO-s).
