I didn't install HealthCheck, since 20+ MB for a diagnostic app with many dependencies is a bit over the top for me.
I did however get the requested info from /proc/cpuinfo and /proc/component_version:
Hardware: Nokia RX-51 board
Revision: 2101
Processor Info: ARMv7 Processor rev 3 (v7l)

My keyboard feels rough compared to a colleagues (that feels smooth).
