MicoAir743v2-AIO-35A: H743 flight control and Bluejay ESCs
Want an H743 flight controller without finding room for a separate ESC board? The MicoAir743v2-AIO-35A puts the controller and four 35A Bluejay ESC channels on one 36 × 36mm board. Its 25.5 × 25.5mm mounting pattern, dual IMUs and microSD slot give compact builds room for more than just the essentials.
Key Highlights
- One board instead of a stack: Integrated four-channel ESC hardware reduces the number of boards you need to mount.
- H743 processing: The STM32H743 runs at 480MHz with 2MB flash, alongside BMI088 and BMI270 IMUs and an SPL06 barometer.
- Room for peripherals: Seven UARTs and an I2C interface provide connections for your receiver, GPS and external sensors.
- Bluejay motor control: Four 35A continuous ESC channels support DShot300/600. That current rating requires good cooling, not wishful thinking.
- Separate accessory supplies: Onboard 5V/2A and 12V/2A BEC outputs serve peripherals with the matching voltage requirements.
Why You Want It
This AIO suits a build where board space matters but you still want connections for GPS, telemetry and other peripherals. MicoAir documents support for ArduPilot, PX4, Skybrush, INAV and Betaflight; choose and configure the appropriate firmware for your aircraft rather than treating the board as ready to fly out of the packet. The microSD slot gives you somewhere to put flight logs, while USB-C keeps the bench connection familiar. There is no onboard compass, so a build that needs one must use a suitable external I2C compass.

FAQ
Does it have a built-in compass?
No. MicoAir documents an external compass connection over I2C.
Can I use bidirectional DShot with every firmware?
No. The ESC hardware supports it, but MicoAir's current documentation says PX4 and INAV do not support the board's bidirectional DShot function. Check the relevant firmware documentation before configuring it.
Can I plug a 5V peripheral into the digital VTX connector?
Not into its power pin. Pin 1 supplies 12V. Check the full pinout and the peripheral's input requirements before connecting anything.
Disclaimer
Check motor current demand, battery voltage, mounting clearance and wiring against the manufacturer documentation before installation. Provide adequate ESC cooling and remove propellers during bench setup. A matching connector shape is not a voltage check.
Still Here?
If your build needs H743 flight control and four Bluejay ESC channels in one mounting position, check the dimensions and pinout, then give the soldering iron something useful to do.
