SEQURE 70A 4in1 ESC 2-8S Brushless Electronic Speed Controller AM32 128K with Heat Sink for FPV Drones UAV
(1) STM32G071 high-performance processor, using AM32 firmware, 2-8S wide voltage input, single-channel continuous current 70A, peak current up to 150A.
(2) Built-in galvanometer, supports telemetry return, and updates motor speed, temperature, current and other data in real time.
(3) High-power MOSFET, ultra-high efficiency conversion, reducing losses and extending flight time.
(4) High copper thickness multi-layer PCB design increases over-current capability, efficient heat dissipation performance, and is not afraid of load pressure.
(5) Precise switch interval time control, speeding up the response speed of the ESC, smooth control, and delicate feel.
(6) PWM frequency supports 16KHz-128KHz, and excellent circuit design to solve the out-of-step problem.
(7) Innovative design, oblique surface soldering pad, motor wiring layout is more beautiful and safe, while reducing welding difficulty.
(8) 20*20mm installation hole spacing design, compact structure, adaptable to various types of racks, easy to install.

3 out of the 4 ESC work - the motor beeps and spins. The fourth - not so much.AM32 configurator randomly can't connect to ESC 1; ESC 4 never connects, so I can't change its settings or update its firmware.The soldering pads are 0.5mm from transistor legs, I sure hope you can solder like a boss, or the ESC may not workI wouldn't bother with this ESC ever again.

Incredible how far technology has come. 70 amps, and this thing is small and pretty light as well. The 20x20 mounting holes are a bit of a bummer, but if your getting this, chances are you're already used to making things work. Have this thing pushing my 7 inch quad with a 6000 mah 4s pack to upwards of 150mph and this esc doesn't even break a sweat.
