Hobbywing XRotor FPV G2 45A 4in1 ESC (AM32)

The Hobbywing XRotor FPV G2 45A is a 4-in-1 ESC on the 20 x 20 mm pattern for 3S-6S FPV quads with a 100-300 mm wheelbase. Each of the four channels is rated 45A continuous and 60A peak, the board weighs 12 g, and it ships with AM32 firmware.

Key features

• AM32 firmware (XROTOR45 F421 target), with settings and updates through a Betaflight-compatible flight controller, the throttle signal cable or a development board
• DShot300, DShot600 and PWM throttle signals
• Built-in current and voltage sensing, so the flight controller can display amps and battery voltage in flight
• Adjustable motor timing, direction and PWM drive frequency (24-96 kHz fixed, or dynamic)
• Wire it to the flight controller with a cable or solder straight to the tabs
• 14AWG battery leads come with an XT60 already soldered on

Specifications

• Continuous / peak current: 45A / 60A per motor
• Battery: 3S-6S LiPo (11.1-22.2 V nominal)
• Firmware: AM32 (XROTOR45 F421)
• Processor: 32-bit ARM, 120 MHz
• Throttle signal: DShot300, DShot600, PWM
• Mounting: 20 x 20 mm
• Size: 40 x 33 x 5 mm
• Weight: 12 g
• Battery leads: 14AWG, 100 mm, XT60
• Motor connection: Solder pads

Pair it with a 20 x 20 mm flight controller and check that the FC's ESC connector pinout matches before plugging in the signal cable. On 6S, solder a low-ESR capacitor across the battery pads to absorb voltage spikes.
