Custom STM32F7 Flight Controller
Budget: ₹12,500 – ₹37,500 INR
I need a bespoke flight-controller board built around the STM32F722 MCU and the ICM42688P gyro. The absolute non-negotiable is seamless, upstream compatibility with iNav / BetaFlight; both if possible
Core specification I must see reflected in the design
• 4 motor outputs plus 2 additional PWM channels for servos so I can run hybrid VTOL and other custom builds.
• Real-time telemetry and 32 MB Blackbox logging.
• Five hard UARTs broken out for VTX, receiver, camera control, ESC telemetry and GPS.
• Full LED-strip support driven directly from the MCU.
• On-board regulation delivering 5 V, 9 V and 3.3 V rails with clearly labeled pads.
• Standard 30.5 × 30.5 mm mounting pattern, 4 mm hole size.
Deliverables
1. Schematic and PCB layout (KiCad preferred, Altium acceptable) that meet the above specs.
2. Clean, manufacture-ready Gerbers, drill files, pick-and-place, and full BOM.
3. A simple iNav/BetaFlight target file or defconfig proving firmware compatibility.
4. Brief bring-up notes covering bootloader flashing, UART mapping and voltage-rail test points.
Acceptance criteria
• Board flashes and boots stock iNav / BetaFlight without modification.
• All six PWM outputs, five UARTs, Blackbox verify in configurator.
If you have prior experience designing STM32-based FCs and can turn a rock-solid, low-noise layout quickly, let’s talk. Online Support till sample is working & tested
