Holybro Tekko32 F4 Metal 4in1 65A ESC

The Holybro Tekko32 F4 Metal is a 30.5 × 30.5 mm 4-in-1 ESC for 4–6S builds of 5 inches and up that pull serious current. Each channel is rated 65 A continuous, and its metal-cased MOSFETs, 3 oz copper PCB and separated drive and control circuits keep it cool and electrically quiet under sustained load.

Key features

• F4 MCU at 150 MHz with PWM frequency adjustable from 16 kHz to 96 kHz (48 kHz default)
• Ships with BLHeli_32 firmware; supports DShot150/300/600/1200, MultiShot, OneShot, ProShot and PWM
• ESC telemetry plus an onboard analog current sensor for accurate mAh readings in the OSD
• 2068 µF of onboard capacitance for noise filtering, with a 1000 µF 35 V capacitor also in the box
• No output BEC, so pair it with a flight controller that has its own regulators

Specifications

• Continuous current: 65 A × 4
• Burst current: 75 A × 4
• Input voltage: 4S–6S LiPo
• Firmware: BLHeli_32
• Current sensor scale: 180
• Mounting: 30.5 × 30.5 mm, M4 holes (M3 grommets included)
• Dimensions: 43 × 44 mm
• Weight: 15.8 g
• In the box: ESC, 4 M3 anti-vibration grommets, 1000 µF 35 V capacitor, 8-pin to 8-pin 1 mm pitch cables (65 mm and 25 mm)

To run near the 65 A rating, give the ESC airflow and use battery leads of at least 12 AWG, well soldered; on 6S, fit the supplied capacitor across the battery pads.
