Aocoda-RC F475S V4 F405 V4 75A 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.
3075S 8-Bit Bluejay ESC
The included 3075S 4-in-1 ESC provides four 75A continuous-current channels, Bluejay firmware, telemetry support and a 3–8S LiPo input range.
Analog and DJI O3 Wiring Support
Dedicated connections are provided for two cameras, an analog VTX, DJI O3, GPS, receivers, a buzzer and an LED strip. CAM1 is enabled by default, while CAM2 can be selected through flight-controller configuration.
Standard 30.5 × 30.5 mm Installation
Both boards use an M3 30.5 × 30.5 mm mounting pattern. The supplied dimension drawing shows an assembled stack height of approximately 13 mm.

FAQ
What is the difference between the F475S V4 and F475 V4?
The F475S V4 uses a 3075S 8-bit ESC with Bluejay firmware. The F475 V4 is a different version that uses a 3075 V2 32-bit ESC. Firmware intended for the 32-bit version must not be used on the F475S V4 ESC.
What flight controller and ESC are included?
The stack includes one F405 V4 flight controller and one 3075S 8-bit 75A 4-in-1 ESC.
What battery voltage does the F475S V4 support?
The supplied technical material specifies a 3–8S LiPo input range for the F475S V4 stack.
Which ESC firmware does this version use?
The supplied ESC firmware reference is Bluejay D_X_30_v0.21.1-RC1-hex. Confirm the installed production-batch firmware before performing an update.
Which flight-controller firmware target is required?
The F405 V4 flight controller uses the AOCODARCF405V3 target for Betaflight, INAV and ArduPilot (ChibiOS).
Does the stack support analog video and DJI O3 wiring?
Yes. It provides an AT7456E analog OSD, dual camera inputs, analog VTX connections and dedicated wiring shown for the DJI O3 system.
What current-sensor scale should be entered?
The supplied F475S V4 wiring diagram shows an amperage-meter scale value of 77.
B2B Procurement FAQ
What should be confirmed before placing a bulk order?
Confirm that the quotation specifies the F475S V4 with the 3075S 8-bit ESC, together with the required input-voltage rating, firmware batch, accessory list and packaging requirements.
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 details 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 flight-controller 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.
