SEQURE Blueson A1 AM32 ESC 6S 65A / 8S 70A

The SEQURE Blueson A1 AM32 ESC is the 20×20 FPV racing drone ESC for pilots who outgrow bargain stacks. Whether you’re building a 6S 65A rocket or an 8S 70A monster, this AM32 ESC gives you dynamic 8K–128K PWM, rock-solid current handling and telemetry without needing a soldering PhD. Think “You’ve watched enough Bardwell smoke tests, now it’s time to avoid being one.”

Why You Want It

Under the heat-soaked conformal coat lives an AT32F421 32-bit brain, fat copper PCB and high-end MOSFETs that shrug at punch-outs and prop-wash. Dynamic PWM keeps throttle inputs smooth, while 2–6S or 2–8S support lets you run anything from chilled 4S to “oops, that’s 8S” insanity. Yes, we profit when you buy one; you get cooler MOSFETs and fewer brown-outs, we get to keep the warehouse lights on. Fair trade.

Specifications

• Model: Blueson A1 (way better than “Generic 20×20 ESC”).
• Processor: AT32F421 32-bit MCU (the tiny brain doing 8K–128K PWM yoga).
• Firmware version: AM32 pre-flashed, supports BLHeli_32 (pick your favourite firmware cult).
• PWM frequency: 8KHz–128KHz dynamic PWM (smoother throttle than your sim meta tune).
• Working voltage: 2–6S or 2–8S LiPo/LiHV depending on version (from sensible to “send it”).
• Continuous current: 65A on 6S / 70A on 8S (for everyday abuse).
• Peak current: 120A on 6S / 150A on 8S (for those brief “full-send” laps).
• Supported protocols: DShot600/300/150, Oneshot, Multishot, PWM (yes, legacy is still invited).
• Telemetry return: Yes – real-time voltage and current instead of guessing by smell.
• Current sensor (galvanometer): Onboard (because “it felt like 80A” isn’t data).
• BEC: None – use your flight controller or a separate regulator (no free 5V fairy here).
• Mounting hole spacing: 20×20mm, Φ4mm/M3 (drops into modern race frames without Dremel therapy).
• Product size: 42.5×36×7mm (L×W×H) – a compact brick of electricity-taming sorcery.
• Weight: 19g (because gravity still exists, sadly).
• Solder pads: Oversized motor and battery pads (designed for humans, not pick-and-place robots).

What’s in the Box*

• 1× SEQURE Blueson A1 6S 65A or 8S 70A ESC (AM32 firmware installed)
• 1× Signal/power wire set or harness (varies slightly by batch, always build-ready)
• 4× Soft-mount grommets for 20×20 stacks
• 1× Tiny sheet of paperwork you’ll skim for three seconds, then ignore

Compatibility

Plays nicely with most 5–7" FPV racing and freestyle frames using a 20×20 stack pattern. Works happily with Betaflight, INAV and other mainstream flight firmware that speaks DShot, Oneshot, Multishot or PWM. If your build can handle 6S or 8S packs and you’re not in CAA paperwork purgatory, this ESC is probably ready to live in it.

Features and Highlights

• High-copper PCB & premium MOSFETs — Better current handling and heat dissipation when you floor it instead of gently “ascending”.
• Dynamic 8K–128K PWM — Finer throttle resolution so your quad sounds less like a lawnmower and more like it belongs in a DRL finals replay.
• 6S and 8S capable — Start sensible on 6S, then “accidentally” upgrade to 8S without replacing the ESC.
• Telemetry & current sensing — See amps and voltage on your OSD, so you land on purpose instead of when the pack gives up.
• Big solder pads — Easier, cleaner joints, especially if your soldering iron has already claimed a few fingertips.
• 20×20 mounting — Designed for modern racing stacks, keeping your build low, clean and easier to turtle mode after that “it’ll buff out” crash.

Product Notes

Ships with AM32 firmware out of the box and supports flashing BLHeli_32 if you prefer to stay in that ecosystem. There’s no onboard BEC, so power your flight controller and accessories from an FC regulator or separate BEC. As always, good airflow and sensible soft-mounting will help keep the magic smoke where it belongs: inside.

AM32 ESC Disclaimer

Accessories may change with batches; the Blueson A1 AM32 ESC stays the same tiny overachiever doing its best not to release any magic smoke.
