Technical Highlights

Mini Flight Controller and ESC Stack

This stack pairs the BLITZ Mini ATF435 flight controller with the separate BLITZ Mini E55S four-in-one ESC. Both boards use a 20 × 20 mm mounting pattern with 4 mm holes.

AT32 Flight Processing and Onboard Sensors

The Mini ATF435 flight controller uses an AT32F435RGT7 MCU, BMI270 gyroscope and DPS310 barometer. It also provides 16 MB of onboard Blackbox flash and an AT7456E analog OSD chip.

2–6S Four-in-One ESC

The Mini E55S ESC supports 2–6S LiPo input and is specified at 55 A continuous and 65 A burst. It provides onboard current sensing and supports DShot150, DShot300, DShot600, MultiShot and OneShot motor-control signals.

Video-Transmitter Control Interface

The flight controller supports SmartAudio and IRC Tramp VTX control protocols. A 5.8 GHz video transmitter is a separate component and is not listed in the manufacturer's standard stack package.

Selection and Installation Notes

Use the specifications for the Mini ATF435 version: BMI270 gyroscope, 16 MB Blackbox flash and 20 × 20 mm mounting.
The FC provides a 5 V / 2.5 A BEC; the Mini E55S ESC itself has no BEC.
Match the Betaflight configuration to the IFLIGHT_BLITZ_ATF435 target before flashing or replacing firmware.
A BLITZ Mini 5.8 GHz VTX appears in the supplied image archive, but it is not included in iFlight's standard packing list for this FC/ESC stack. Confirm any VTX-inclusive bundle as a separate offered configuration.

FAQ

Is this a single-board AIO flight controller?

No. The BLITZ Mini ATF435 and Mini E55S are separate flight-controller and four-in-one ESC boards assembled as a stack.

Which gyroscope and Blackbox capacity belong to the Mini ATF435?

The Mini ATF435 uses a BMI270 gyroscope and has 16 MB of onboard Blackbox flash. Specifications for the larger BLITZ ATF435 version should not be substituted.

What battery input and current ratings apply to the Mini E55S ESC?

The ESC supports 2–6S LiPo input and is specified at 55 A continuous and 65 A burst.

Does the stack include a 5.8 GHz video transmitter?

The manufacturer's standard stack packing list does not include a VTX. A VTX image appears in the supplied archive, so confirm the exact offered configuration if a transmitter is required.

What is the flight-controller firmware target?

The BLITZ Mini ATF435 flight controller uses the IFLIGHT_BLITZ_ATF435 target. Check the target and board revision before flashing firmware.

B2B Procurement FAQ

What is included in iFlight's standard FC/ESC stack package?

iFlight lists one BLITZ Mini ATF435 flight controller, one BLITZ Mini E55S four-in-one ESC, and power cables plus ESC signal wires. Confirm the contents of the specific offered SKU during quotation.

Can a 600 mW VTX be quoted with the stack?

The archive shows a separate BLITZ Mini VTX, but its inclusion is not established by the standard stack package. Confirm the exact VTX model, price and bundle contents during quotation.

Which fitment details should be checked before a bulk order?

Check the 20 × 20 mm mounting pattern with 4 mm holes, the 30.5 × 27 mm FC outline, 2–6S battery input, motor current requirements, cable connections and required video equipment.

Are MOQ, lead time, warranty and delivery terms established?

The supplied product material does not establish these terms for this offering. Confirm them during quotation.
