Connecting a Yukon Host board to a Raspberry Pi?

Support
1

I’d like to use the Yukon Host and its motor and servo controllers on a robot, but the robot is running a Raspberry Pi as its master controller (providing e.g., higher level control and WiFi connectivity). Is there any way to communicate with the RP2040 on the Yukon Host from a Raspberry Pi? I can’t use UARTs as there aren’t enough of them on the Pi, and serial isn’t fast or reliable enough.

And a second question that somewhat relies upon the first: is there any way to connect or extend more than one Yukon host board so that one has more than six Yukon module connections available? I need between 8-10 modules for this robot.

Thank you.

UART is serial btw. and I think this is your only option. The Pi has four UARTs and if this isn’t enough, you should look for some SPI to UART bridges. There are 2x and 4x bridges available. And don’t even think about I2C if you already know that “serial isn’t fast”.
