Designed to run ArduPilot firmware , it combines an ultra-fast STM32H7A3 processor with a modern ICM42688P IMU, SPL06 barometer, onboard OSD, and MicroSD blackbox logging—making it ideal for long-range, survey, mapping, and experimental aircraft projects.\u003c\/p\u003e\n\u003cp\u003eWith support for 3–6S LiPo input, three independent high-current BEC rails, and an integrated digital power monitor rated for up to 164A burst, the H7A3 Wing removes the need for external PDBs or current sensors in most builds. Eleven PWM outputs, six UARTs with inversion, CAN, I2C, and multiple ADC inputs give you huge flexibility for servos, ESCs, GPS, telemetry radios, airspeed sensors, gimbals, and digital video systems.\u003c\/p\u003e\n\u003cp\u003eThe board uses a multi-layer stacked design with cover plates and includes a USB-C \/ buzzer extender for easy bench setup. Standard 30.5 × 30.5 mm mounting keeps installation straightforward in most airframes.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSTM32H7A3 Cortex-M7 MCU running at 280 MHz\u003c\/li\u003e\n\u003cli\u003eOptimised for ArduPlane \/ ArduCopter platforms\u003c\/li\u003e\n\u003cli\u003eICM42688P gyro + SPL06-001 barometer\u003c\/li\u003e\n\u003cli\u003eAT7456E analog OSD + MicroSD blackbox logging\u003c\/li\u003e\n\u003cli\u003eIntegrated I2C digital current \u0026amp; voltage sensor (no calibration required)\u003c\/li\u003e\n\u003cli\u003eUp to 164A burst current monitoring\u003c\/li\u003e\n\u003cli\u003e11 PWM outputs for servos or ESCs\u003c\/li\u003e\n\u003cli\u003e6 UARTs with built-in inversion\u003c\/li\u003e\n\u003cli\u003eCAN and I2C ports via JST-GH connectors\u003c\/li\u003e\n\u003cli\u003eTriple-rail power system for avionics, video and servos\u003c\/li\u003e\n\u003cli\u003eStandard 30.5 × 30.5 mm mounting pattern\u003c\/li\u003e\n\u003cli\u003eUSB-C extender with passive buzzer included\u003c\/li\u003e\n\u003cli\u003eFC Firmware\u003c\/li\u003e\n\u003cli\u003eArduPilot: MATEKH7A3 (4.6 or newer)\u003c\/li\u003e\n\u003cli\u003eArduPlane https:\/\/firmware.ardupilot.org\/Plane\/beta\/MatekH7A3\/\u003c\/li\u003e\n\u003cli\u003eArduCopter https:\/\/firmware.ardupilot.org\/Copter\/beta\/MatekH7A3\/\u003c\/li\u003e\n\u003cli\u003eFlashing with STM32CubeProgrammer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMCU: STM32H7A3RIT6, 280MHz Cortex-M7, 1.4MB RAM, 2MB Flash\u003c\/li\u003e\n\u003cli\u003eIMU: ICM42688P\u003c\/li\u003e\n\u003cli\u003eBaro: SPL06-001\u003c\/li\u003e\n\u003cli\u003eOSD: AT7456E\u003c\/li\u003e\n\u003cli\u003eBlackbox: MicroSD socket\u003c\/li\u003e\n\u003cli\u003eI2C digital power monitor\u003c\/li\u003e\n\u003cli\u003eUSB\/Beep Extender with Type-C(USB2.0)\u003c\/li\u003e\n\u003cli\u003e9V\/12V output ON\/OFF switchable\u003c\/li\u003e\n\u003cli\u003eDigital video OSD is supported by any spare UART\u003c\/li\u003e\n\u003cli\u003eVbat Input: 9~30V (3~6S LiPo)\u003c\/li\u003e\n\u003cli\u003eBEC 5V\/4v5: 2.5A cont. \/3A peak\u003c\/li\u003e\n\u003cli\u003eBEC 9V\/12V: 2A cont. \/3A peak\u003c\/li\u003e\n\u003cli\u003eBEC Vx: 8A cont. \/12A Peak,  output 5V Default, 6V or 7.2V option.\u003c\/li\u003e\n\u003cli\u003eLDO 3.3V: Max.200mA\u003c\/li\u003e\n\u003cli\u003eNo calibration required.\u003c\/li\u003e\n\u003cli\u003eCurrent sensing resistor: 0.00025 ohm\u003c\/li\u003e\n\u003cli\u003eLoad current on current sensing resistor:  100A(Continuous),  164A(Burst)\u003c\/li\u003e\n\u003cli\u003eVoltage accuracy: ± 0.1%\u003c\/li\u003e\n\u003cli\u003eCurrent accuracy: ± 2%\u003c\/li\u003e\n\u003cli\u003eINA2xx I2C address:  0x45 (69)\u003c\/li\u003e\n\u003cli\u003eParameters BATT_MONITOR  -\u0026gt;21 (INA2xx) BATT_SHUNT   -\u0026gt; 0.00025 BATT_MAX_AMPS  -\u0026gt; 164 BATT_I2C_BUS   -\u0026gt; 0 default BATT_I2C_ADDR -\u0026gt; 0 default (or 69)\u003c\/li\u003e\n\u003cli\u003eBATT_MONITOR  -\u0026gt;21 (INA2xx)\u003c\/li\u003e\n\u003cli\u003eBATT_SHUNT   -\u0026gt; 0.00025\u003c\/li\u003e\n\u003cli\u003eBATT_MAX_AMPS  -\u0026gt; 164\u003c\/li\u003e\n\u003cli\u003eBATT_I2C_BUS   -\u0026gt; 0 default\u003c\/li\u003e\n\u003cli\u003eBATT_I2C_ADDR -\u0026gt; 0 default (or 69)\u003c\/li\u003e\n\u003cli\u003eDupont 2.54 pins  (Board is shipped unsoldered)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6x Uarts (1,2,3,4, 5, 6) with built-in inversion.\u003c\/li\u003e\n\u003cli\u003e11x PWM outputs\u003c\/li\u003e\n\u003cli\u003e1x I2C\u003c\/li\u003e\n\u003cli\u003e1x CAN\u003c\/li\u003e\n\u003cli\u003e4x ADC (VBAT, Current, VB2, Cur2)\u003c\/li\u003e\n\u003cli\u003e3x LEDs for FC STATUS (Blue, Red) and 3.3V indicator(Red)\u003c\/li\u003e\n\u003cli\u003e2x JST-GH1.25_4pin connector for CAN and I2C\u003c\/li\u003e\n\u003cli\u003e1x H7A3-WING\u003c\/li\u003e\n\u003cli\u003e1x USB(Type-C)\/Beep (Passive buzzer) Extender with 6pin cable\u003c\/li\u003e\n\u003cli\u003e1x 20cm JST-SH-6P to JST-SH-6P cable for USB extender.\u003c\/li\u003e\n\u003cli\u003e2x 20cm JST-GH-4P to JST-GH-4P cable for CAN \u0026amp; I2C port\u003c\/li\u003e\n\u003cli\u003e1x Rubycon ZLH 35V 470uF capacitor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Matek Systems","offers":[{"title":"Default Title","offer_id":58941163110732,"sku":"WFC-H7A3WING","price":78.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1087\/9952\/5196\/files\/Matek-H7A3-Wing.jpg?v=1790286367","url":"https:\/\/dronepart.co.uk\/products\/matek-h7a3-wing-ardupilot-flight-controller","provider":"My Store","version":"1.0","type":"link"}
