Spotted this on the e-ink subreddit and immediately ordered one. A custom solar energy dashboard, running for months on a single charge — sold.
What makes TRMNL special is the philosophy behind it: fully open source, hackable by design, screws instead of glue. Don't want to build your own hardware? Just buy the assembled version. Don't want to depend on their cloud? Run one of several self-hosted server implementations — including one maintained by TRMNL themselves.
That last part is what gets me. A company that open-sources its own server backend isn't just paying lip service to the maker community. That's genuine commitment.
The plugin ecosystem (900+) and the no-subscription model seal the deal. This is how hardware products should be built.
