2-4S Continuous 30A ESC

By integrating 2oz thick copper on the board to enhance thermal efficiency and current handling, the Cube FC features a significantly upgraded 2-4S Bluejay ESC—delivering a robust 30A continuous current, up from 20A in F405 FCs. This ensures reliable power delivery to meet the surge demands of Pavo whoops during aggressive freestyle maneuvers, giving pilots the confidence to push their limits.

Serial ELRS 2.4G RX

Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.

Plugin and unplug the flight controller three times;
Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
If the receiver has a solid light, it's bound.

The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.

Plug in your FC to your computer, connect to ExpressLRS Configurator instead of Betaflight Configurator;
Choose target "BETAFPV 2.4GHz AIO RX";
Flash using the BetaflightPassthrough option in ExpressLRS Configurator.

Bluejay ESC Firmware

With BB51 ESC solution, Cube Brushless Flight Controller is based on V0.19.2 48KHz Bluejay, it supports DShot150, DShot300, DShot600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies.

DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.

How to Use Serial Ports, Intergrated RX and VTX

Please note that by default, UART3 is connected to the RX and UART4 is connected to the HD VTX. To release UART3, please remove the resistor. Additionally, this FC reserves 2 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, or other serial devices. You can refer to the below pictures.
