Rui CarmoThe Xteink X4 is a small open e-ink reader that has become more interesting because of the growing CrossPoint ecosystem around it. The hardware itself is attractive mostly as a hackable reading device: simple, portable, and now backed by a fairly active alternative firmware community.
The most sensible starting point is the upstream CrossPoint Reader firmware, then branch out into more specialized forks only if you need particular UX changes, CJK support, or more experimental features.
