The classical F4 Brushed Flight Controller comes back with new changes and particular shapes. Build-in CC2500 chip, the default protocol is configured to Frsky D8 out of the factory and can be adjusted to Frsky D16 FCC, Frsky D16 LBT, or Futaba. Besides, the power cable adopts BT2.0 connector instead of PH2.0, which improves the performance and is compatible with BETAFPV BT2.0 series batteries.

What's the Upgrade

Compared with the previous version F4 Brushed Flight Controller V1.2, now the V2.0 version comes with SPI Frsky D8 receiver that can be compatible with Futaba S-FHSS, Frsky D16 FCC, and Frsky D16 LBT protocol. The power cable applies BT2.0 connector instead of PH2.0, which solves the problem of voltage sag, and the discharge can be more efficient, bringing this board a better performance on function for power and responsiveness. What's more, with the compatibility of BETAFPV BT2.0 series batteries, it is convenient to upgrade in the future. Besides, it supports custom RGB lights on the Betaflight configuration, which makes your drone unique from others.
