A fast, low-latency, open-hardware e-paper monitor and dev kit

Three years ago, I posted about modding a ThinkPad T480 into an e-ink laptop: https://news.ycombinator.com/item?id=26245563

That turned into a community project and eventually into building our own FPGA-based e-ink display controller to improve refresh speed and reduce ghosting.

The result is a dev kit and monitor: open hardware, supports 6–13" monochrome and color e-ink panels over HDMI or USB-C, up to 75 Hz with sub-100 ms latency, and includes a C API.

I'm probably getting one for desktop use, but I'm also curious for other use cases, what's the power usage like? while idle or doing high frame rate video?

Great! The board uses about 1-1.5W under continuous use with no OS/kernel power optimizations.
