The JHEMCU RuiBet 45A is listed under flight controllers but the page describes a 4-in-1 brushless electronic speed controller for FPV freestyle and racing drones. It supports 3-6S LiPo batteries with BLHeli_S firmware and the DShot600 protocol.
The specification list gives a 45A current rating, a 3-6S power supply and a 30x30 mm mounting size, and the package is listed as one JHEMCU RuiBet 45A unit. The page showed the item in stock (SKU RS9369).
45A continuous current: as listed.
BLHeli_S firmware: as listed.
DShot600 protocol: as listed.
3-6S LiPo support: as listed.
4-in-1 ESC design: as listed.
30x30 mm mounting: as listed.
A flight controller is the brain of a multirotor or fixed-wing aircraft. It reads the gyroscope, and where fitted the accelerometer, barometer and compass, and runs a control loop that compares what the aircraft is doing with what the pilot asks for. It then sends new speed commands to the motors through the ESCs or servos many times each second. A faster processor and a better gyro allow a higher loop rate and a more locked-in feel.
Wiring and firmware decide what the board can do. The number of UARTs limits how many receivers, GPS units, telemetry radios and video systems you can connect, the PWM or motor outputs limit how many motors and servos it can drive, and the input voltage range must suit your battery and power module. Before you buy, check that the firmware you want to run supports the board and that its mounting pattern fits your frame.
Set up carefully. Flash a firmware that is listed as supported, configure the receiver protocol, set the motor order and direction, calibrate the accelerometer and, for larger aircraft, the compass, and always test with the propellers removed first. Keep the board isolated from vibration with soft mounts where the design calls for them, and never power it with a supply that is outside the rated input voltage.
Keep the aircraft safe. Confirm your failsafe settings and arming switch before the first flight, keep a backup of your configuration, and update firmware only when you have a reason to. A flight controller is a safety-critical part, so use the wiring diagram from the maker and avoid guesswork with power connections.

Because the page describes an ESC, pair it with a separate flight controller that supports DShot600 and a 30x30 mounting pattern.
The page lists DShot600 and BLHeli_S. It does not list a burst rating.
