Aocoda-RC F475 V4 F405 V4 75A AM32 FPV Stack
Technical Highlights
STM32F405 Flight Control Platform
The F405 V4 flight controller uses an STM32F405RGT6 processor running at 168 MHz with 1 MB flash. It integrates an ICM42688P gyroscope, SPL06-001 barometer, AT7456E OSD and 16 MB blackbox storage.
3075 V2 32-Bit 75A 4-in-1 ESC
The included 3075 V2 ESC provides four 75A continuous-current channels, telemetry support and 32-bit firmware. The supplied technical material and PCB marking specify a 3–8S LiPo input range.
Analog and DJI O3 Wiring Support
Dedicated camera, analog VTX, DJI O3, receiver, GPS, buzzer and LED connections simplify installation. Two camera inputs are provided, with CAM1 selected by default and CAM2 available through configurable switching.
Standard 30.5 × 30.5 mm Mounting
Both boards use an M3 30.5 × 30.5 mm mounting pattern. The flight controller measures 37 × 37 mm, while the ESC measures 44.5 × 40.5 mm.

FAQ
What flight controller and ESC are included in the F475 V4 stack?
The stack includes one F405 V4 flight controller and one 3075 V2 32-bit 75A 4-in-1 ESC.
What battery voltage does the F475 V4 support?
The supplied technical sheet and ESC PCB marking specify a 3–8S LiPo input range. Because the current manufacturer product-page title shows a different range, the exact production-batch rating should be confirmed before purchase.
What firmware target is used by the flight controller?
The flight controller uses the AOCODARCF405V3 target for Betaflight, INAV and ArduPilot (ChibiOS).
Does the stack support analog video and DJI O3 wiring?
Yes. The flight controller provides analog camera and VTX connections, an AT7456E analog OSD, dual camera inputs and dedicated wiring shown for the DJI O3 system.
Which ESC firmware should be flashed?
The supplied material lists AM32_AORC_K_A_F421_2.16.hex and AocodaRC-BL32-4IN1-60A-Rev.32.10 as alternative firmware references. Confirm the firmware already installed on the production batch before flashing either file.
What mounting pattern does the stack use?
Both boards use an M3 30.5 × 30.5 mm mounting pattern. The flight controller measures 37 × 37 mm and the ESC measures 44.5 × 40.5 mm.
B2B Procurement FAQ
What should be confirmed before placing a bulk order?
Confirm the required production batch, input-voltage rating, installed ESC firmware, accessory list and packaging requirements during quotation.
Are samples and low-volume trial orders available?
Sample availability, minimum order quantity, sample cost and lead time must be confirmed during quotation.
Can OEM packaging or product labeling be provided?
OEM packaging, labeling, branding and documentation requirements must be reviewed and confirmed before an order is accepted.
Which technical information should buyers provide for compatibility review?
Provide the intended LiPo cell count, motor and propeller combination, expected current demand, receiver type, video system and required firmware environment.
Are compliance documents and warranty terms included?
Required compliance documents, inspection standards, warranty coverage and after-sales terms must be confirmed for the quoted production batch.
