Review: Holybro Kakute F7 V1.5 Flight Controller

Holybro released a new version of the Kakute F7, the V1.5! In this post we are going to take a look what’s new and whether you should upgrade from the predecessor.

See this article to learn why you should get F7 Flight controllers.

Where to Buy Kakute F7 V1.5?

Product Page:

This is a NON-AIO flight controller, meaning it’s meant to be used with a 4in1 ESC’s like a stack. You can also buy this FC with the Tekko32 4in1 ESC in a bundle:

In the box there are the following accessories:

  • double sided foam tape for installing the detachable Gyro sensor
  • 8-pin ribbon cable for 4in1 ESC


  • Target: KTF7 (Kakute F7)
  • MCU (Processor): STM32F745
  • Soft-mounted IMU (Gyro): MPU6000
  • Input Voltage: 3S-6S
  • BEC: 5V/2A, 3.3V/0.2A
  • 6 UART’s
  • 6 motor outputs allows for hexacopter configuration
  • Onboard BMP280 Baro Sensor
  • Micro SD card slot for blackbox recording
  • Support Betaflight OSD
  • Dimension: 35x41x7mm
  • Weight: 8g

What’s New in the V1.5?

The previous version says V1.2 on the board, but I am pretty sure the one I have was from the first batch they sold, so maybe they already went through a couple of revisions during beta testing.

And here is the latest Kakute F7 V1.5:

The first difference I spotted is the 180 degree rotated gyro sensor, so as the ribbon cable, which is now connected to the middle of the board instead of to the edge.

They also changed the Gyro from the ICM20689 to a MPU6000.

The ICM20689 was used in the first place because it was able to run 32KHz looptime, but going forward it seems like Betaflight will be limited to 8KHz, which the MPU6000 is capable of. I guess that’s the reason that Holybro decided they might as well just use MPU6000, it’s less noise sensitive and less problematic in general.

They also changed the location of the LED’s. That’s about it, the rest such as pin-out, components and schematics remain more or less the same.

The bottom of the boards is nearly identical.

Another change is the Gyro sensor interface.

It used to be a ribbon cable directly soldered to the flight controller, but it’s now a solder-free push pin design. They said this is a more reliable solution, I am not sure about that because it doesn’t take much to lift it off the board. I guess only actual flying and crashing this flight controller will tell.

But it’s certainly easier to remove and replace the gyro when you need to. Not that you need to do very often. I only had to change one in the two years I have been flying the Kakute flight controllers.

And it was extremely difficult to replace, because firstly, the solder pads are extremely small, and the ribbon cable plastic just burns away by the solder iron if you leave it on two second too long.

Not much has changed. I don’t think this is the usual new product release, but just an update that Holybro wants people to know about.

The new gyro and interface are positive and welcome changes, but not enough for you to replace your existing Kakute boards. If you already got a Kakute F4 or F7 board, no need to upgrade, just carry on!

    I highly enjoy reading your stuff man, thanks a million!! Off beat question here…but those copper/brass looking standoffs in that first picture at the top of this page….where can i find those? LOL I’m building my first 7″ and trying to make it as clean and nice as possible. I need those !! :)

    Thanks for the update Oscar. I have been checking to see where I could get two v1.5’s for my next builds. But if there is little improvement in v1.5 there is no reason to bother, i’ll just stick with the older version
