Kakute F4 carrier board for Raspberry Pi

Blog

Hi all,

I’m planning to do a second production run of the boards.

Features will generally be the same, but I will:

  • Upgrade the power supply to support the Raspberry Pi 4
  • Better placement of ports and pins
  • HAT EEPROM to comply with Raspberry Pi HAT spec
  • Other small bug fixes

I suspect the cost will be a little more than the previous boards - around $30-35USD, plus $10-20USD postage.

If anyone wants a board, PM me with the quantity of boards and country of delivery by 31/10/2019

Hello! I’m not sure if you are still involved with this project. This hat works for Kakute F7? If not, could you pass me some guidelines to connect the Kakute F7 to the Raspberry Pi 3 or 4 using only UART ports of RPi? I’m trying since last sunday without success… :confused: Any tip would be very appreciated! Thanks in advance.

It’s been on the backburner for a while, as I’ve been working on another (https://www.rpanion.com/product/pi-connect-lite/) board. I’ve got plans to get back to this in the next few months.

No, as the F4 and F7 have different pinouts.

Sure, connect the following:
Kakute F7 R1 pin ⇾ Pi GPIO14 (pin 8)
Kakute F7 T1 pin ⇾ Pi GPIO15 (pin 10)
Kakute gnd pin ⇾ Pi gnd (pin 6, 9 etc)

Then configure the Pi (using raspi-config) to enable the UART and disable the UART console.

The /dev/serial0 port will then be available on the Pi for the telemetry.

If you want a pre-built Raspberry Pi disk image, I’ve recently built one over at https://www.rpanion.com/software/

Thanks a lot, bro!
I forgot to connect the ground, since the power source of my RPi4B and Kakute F7 are different in my bench tests. Everything working now… :call_me_hand:
