FPV Flight Controller Sourcing from China | STM32F4/F7/H7 FC Boards | Factory-Vetted by SourcingProChinaProduct OverviewSourcingProChina is a sourcing agent based in China, specializing in connecting overseas drone brands, assemblers, and industrial UAV integrators with vetted flight controller (FC) manufacturers across China's drone electronics supply chain. Rather than reselling generic stock, we conduct factory verification, sample validation, and quality inspection on your behalf before shipment.Through our supplier network, we currently source FC boards built around STM32F405, STM32F722, and STM32H743VIH6 processors, equipped with ICM42688P gyroscopes, onboard barometers (SPL06/DPS310), and configurable BEC outputs. All units we procure are pre-tested for mainstream firmware compatibility — BetaFlight, INAV, or ArduPilot — with 6–7 UART ports, 16MB or MicroSD blackbox logging, and industry-standard 30.5×30.5mm mounting patterns.If you need a specific firmware configuration, custom silkscreen/branding, or an alternative MCU not listed below, tell us your requirement and we will identify and vet a matching factory for you.Technical SpecificationsModelMCUGyroBarometerBECBlackboxUARTInput VoltageFirmwareMountingDimensionsF405 FCSTM32F405RGT6ICM42688PSPL065V/3A; 12V/2.5A16M63-8SBetaFlight/INAV/ArduPilot30.5×30.5mm (Φ4mm)39.8×38.7×8mmF722 FCSTM32F722RET6ICM42688PSPL065V/3A; 12V/2.5A16M63-8SBetaFlight/INAV30.5×30.5mm (Φ4mm)39.8×38.7×8mmH743 WingSTM32H743VIH6ICM42688PDPS3105V/2A; 12V/2AMicroSD73-8SMATEKH74330.5×30.5mm54×36×13mmH743 SlimSTM32H743VIH6ICM42688PDPS3105V/3A; 12V/3AMicroSD73-8SMATEKH74330.5×30.5mm37×38mmCommon SpecificationsSBUS port: UART3 6-PinDJI Air Unit Plug: 6-PinExternal device direct plug: supportedNote: Specifications above reflect the current factory-supplied datasheets in our sourcing network. Actual batch tolerances, firmware version, and certification documents will be confirmed and shared with the sourcing report prior to order confirmation.Key AdvantagesSourced from vetted manufacturers, not middleman stock – Every FC model listed is traceable to a specific factory we have verified through sample testing and, where required, on-site or third-party audit.Multiple MCU options – We can source F4, F7, and H7 based boards depending on your target performance and budget tier.High-precision ICM42688P gyro – Standard across the boards in our network, chosen for stable attitude sensing in turbulent flight conditions.Flexible BEC outputs – 5V/3A and 12V/2.5A (or 12V/2A–3A depending on model) to power VTX, camera, and receiver without a separate BEC module.Ample UART ports – 6–7 UARTs across models for GPS, compass, SBUS, and telemetry integration.Standard mounting footprint – 30.5×30.5mm hole spacing with Φ4mm holes, compatible with most 7–17 inch drone frames.Firmware flexibility – BetaFlight default on F405/F722; INAV and ArduPilot supported on select models; H743 boards run MATEKH743 firmware.End-to-end sourcing support – Sample procurement, QC inspection, consolidated logistics, and factory communication handled on your behalf, reducing the risk of dealing directly with unfamiliar suppliers.Application Scenarios7-inch to 17-inch FPV racing and freestyle dronesIndustrial quadcopters and hexacopters for surveying and inspectionFixed-wing UAVs (H743 Wing)Long-range mission-critical drones requiring multiple peripheral connectionsOEM/private-label drone programs needing a China-based sourcing partner to manage factory relationshipsFAQQ1: What firmware is pre-installed on these flight controllers?Boards sourced through us are pre-flashed with BetaFlight as the factory default. F405 also supports INAV and ArduPilot; F722 supports INAV; H743 series ships with MATEKH743 firmware. If your project needs a different default configuration, we can request custom flashing from the factory before shipment.Q2: What is the input voltage range?All models support 3–8S LiPo input (approx. 11.1V to 33.6V), as confirmed on each factory's datasheet.Q3: Can I connect a DJI Air Unit to these FCs?Yes. All boards in our sourcing network include a 6-Pin DJI Air Unit plug for direct connection — we verify this during incoming sample inspection.Q4: What is the blackbox storage capacity?F405 and F722 boards have 16MB onboard memory. H743 boards support MicroSD cards (SDIO interface) for expanded logging capacity.Q5: Are these boards compatible with 30.5mm mounting patterns?Yes. All models use the standard 30.5×30.5mm mounting hole spacing with Φ4mm holes, which we confirm against physical samples before bulk order.Q6: Why source through SourcingProChina instead of contacting a factory directly?SourcingProChina is a sourcing agent based in China. We manage supplier vetting, sample validation, price negotiation, QC inspection, and export logistics on your behalf — reducing language, quality-control, and payment-security risks for overseas buyers who don't have a presence in China.Procurement InformationCustomizationOEM/ODM coordination available — firmware configuration, silkscreen/branding, and hardware variant sourcing arranged through our factory networkSample PolicySample sourcing available for order qualification (sample cost + shipping fee applies); we can arrange third-party inspection before full paymentPayment TermsT/T, L/C, or other terms negotiable with factory, with escrow/staged-payment structuring available through SourcingProChinaQC & VerificationPre-shipment inspection and factory audit service can be arranged on requestRequest a sourcing quote — Contact SourcingProChina with your target volume, firmware requirement, and application (racing, industrial, fixed-wing) to receive a factory-matched quotation and sample timeline.
