Support for Raspberry Pi 1

please is Balena cloud still support Raspberry Pi v1? I read that yes, but I do not see it in device type list.

Yes, it is supported, it is named “Raspberry Pi (v1 / Zero / Zero W)” in the device list.

If you’ve created a raspberry pi 3 application, you won’t be able to add a raspberry pi 1 device to this application as the architectures are not the same (armv6 on the rpi1)
