PCBSync Engineering Tools

Design the board
that makes a drone fly.

Drone PCB is the free engineering workspace for the heart of every drone — the flight-control board. Explore what's on a drone control board, learn each drone part, estimate your drone PCB cost, and size copper traces before you ever order.

      Design tools

      Size the copper before you route.

      Two calculators every drone PCB needs: an IPC-2221 trace-width tool for your power and motor nets, and a motor power budget to translate your propulsion choice into board current.

      Minimum external trace width (IPC-2221 guideline) for a target current and temperature rise.

      Motor power budget

      Turn your propulsion setup into total board current so your power plane and VBAT traces are sized right.

      Layer stack-up

      Why most flight controllers use four layers.

      A clean, uninterrupted ground plane right beneath the gyro is the single biggest win for a quiet drone PCB. Four layers let you give the IMU a solid reference, isolate power, and still route fine-pitch parts. Switch the stack to see the trade-off.

      From schematic to a board that flies.

      A practical order of operations for laying out a drone control board. Each stage builds on the last — skipping the ground plane or the power budget is what bites later.

      STEP 01

      Lock the requirements

      Frame size, motor and ESC current, battery cell count, radio protocol, and whether you need GPS or HD video. These decide your board size, layer count and connector set.

      STEP 02

      Schematic & part selection

      Choose the MCU, IMU, regulators and OSD. Decouple every rail close to its pin, and keep the gyro's analog supply clean and separate.

      STEP 03

      Stack-up & ground plane

      Commit to a 4-layer stack with a continuous ground directly under the IMU. This is the foundation for a low-noise, flyable board.

      STEP 04

      Placement

      Center the IMU near the board's mechanical center, isolate it from the regulators' switching nodes, and keep the MCU short-trace to every sensor.

      STEP 05

      Power & motor routing

      Size VBAT and motor traces from your power budget, pour copper for high-current paths, and stitch grounds with plenty of vias.

      STEP 06

      DFM check & order

      Verify clearances, drill sizes, and a manufacturable stack, then send it to fabrication. Start your Drone PCB order with PCBSync.

      Drone PCB FAQ

      Drone questions, answered.

      What is a drone PCB?

      A drone PCB is the printed circuit board at the heart of a drone — most often the flight controller. It carries the microcontroller, the IMU (gyroscope and accelerometer), power regulation, and the connections that drive the motors through the ESCs. It reads the sensors, runs the flight firmware, and turns your stick inputs into precise motor outputs hundreds of times a second.

      How much does a drone PCB cost?

      A small prototype flight-controller board can be just a few dollars per board for bare fabrication at low quantity. Cost rises with layer count, copper weight, surface finish (ENIG costs more than HASL), and especially assembly. Use the cost estimator above for an indicative figure, then request a verified quote from PCBSync for your exact design.

      What parts are on a drone control board?

      A typical drone control board carries an MCU, a 6-axis IMU, a barometer for altitude, power management for the 5V / 3.3V / 9V rails, an OSD to overlay flight data on FPV video, motor outputs to the ESCs, a radio receiver interface, and often onboard flash for blackbox logging. Explore each one in the board section above.

      How many layers does a drone PCB need?

      Simple flight controllers can be 2-layer, but most modern FCs use 4 layers — signal, ground, power, signal — to keep a continuous ground plane under the gyro, cut noise, and route fine-pitch components. Dense 4-in-1 ESC and all-in-one (AIO) boards may step up to 6 layers.

      Can I design a drone control board myself?

      Yes. Start from a reference flight-controller schematic, follow the design sequence above, size your copper with the trace-width tool, and keep a clean ground plane under the IMU. When the layout passes a DFM check, send it to PCBSync to fabricate and assemble.
