Sequre Blueson A2 2-8S 70A ESC (AM32)
The Sequre Blueson A2 70A is a 4-in-1 ESC rated up to 8S, which runs AM32 firmware.
Overview:
The Sequre Blueson A2 is a high-current 4-in-1 ESC designed for powerful FPV quad builds, supporting 2-8S LiPo/LiHV batteries and delivering 70A continuous current per motor channel. It runs AM32 firmware on an AT32F421 32-bit processor, with adjustable PWM frequencies from 8kHz to 128kHz for flexible motor control tuning.
A thick-copper multilayer PCB and high-power MOSFETs are designed to handle demanding current loads while improving heat dissipation. Integrated current sensing and ESC telemetry provide operating data to a compatible flight controller, while the angled, extended motor solder pads help simplify wiring. With a 30.5 × 30.5mm mounting pattern, the Blueson A2 is suited to larger freestyle, racing and long-range builds that need substantial current capacity.
Features:
- AM32 firmware: Allows motor control settings to be configured using compatible AM32 tools.
- Adjustable PWM frequency: Supports tuning motor response to suit different motors and propeller setups.
- High-current circuit design: Thick copper layers and high-power MOSFETs help manage electrical losses and heat under load.
- Integrated current sensing and telemetry: Provides current and ESC operating data to a compatible flight controller.
- Angled, extended solder pads: Give motor wiring more space and simplify soldering.
- Flexible motor control protocols: Supports a range of digital and analogue ESC signal protocols.
- Compact 4-in-1 layout: Combines all four motor channels on one board to reduce wiring and simplify installation.
