Re: CM4 to CM3 adapter compatibility

I've did a quick test if this could fit mechanically and I guess with some Kapton tape covering the screw terminals underneath the adapter this MIGHT work. No idea about the IO pins nor is this anything we will ever support officially.

Re: RevPi3 on Ubuntu

You can have a look at our overlay files. They are located in our kernel repository. The overlay for the Core 3(+) / Core S can be found here: https://github.com/RevolutionPi/linux/b ... verlay.dts

Re: Can't send CAN messages with RevPi Con CAN

Hi Andrea, I'm no can expert, but something I've spotted in your script: os.system("sudo ip link set can0 type can loopback on") Why do you enable the loopback mode if you want to transmit over wire? With loopback enabled RX and TX will be connected internally and no data is transmitted ov...

Re: Schematic of the CM4+ used in the Connect S/SE

The CM4S is a module which is only available for (by RPi) selected OEMs in order to overcome the CM3 shortage (/absence).

Re: Sensor Array System

Hi EduardoH, if you want to use the existing I2C sensors the pico would be a good option. You can connect the pico via USB and send the sensor data via serial. Another cool solution: Use the pico as USB to I2C adapter like this: https://hackaday.com/2022/10/31/need-an-usb-i2c-adapter-use-your-pico/ ...

Re: erster Zugriff auf Core S fehlgeschlagen

Hallo Matthias, freut mich zu hören, dass nun alles läuft. Meine Vermutung ist, dass numpy und Konsorten mit der Zeit immer komplexer werden und somit mehr Sourcecode übersetzt werden muss. Auch kommt immer mal wieder etwas an Abhängigkeiten hinzu. Deswegen versuche ich nach Möglichkeit immer mit vo...

Re: Schematic of the CM4+ used in the Connect S/SE

The datasheets of the compute module can be downloaded on the Raspberry Pi website. The datasheet for the CM4S is this one: https://datasheets.raspberrypi.com/cm4s ... asheet.pdf

(the GPIO mapping is similar, besides SPI2?)

Re: Which is the correct DTBO for a Connect S?

The eeprom is only part of core se and future models like connect 4. The connect se is similar to the connect 3 / s (without the ethernet part on pibridge).

Re: Which is the correct DTBO for a Connect S?

Is it possible that you selected the Connect SE instead Connect / Connect 3(+) / Connect S ?
