InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
the reMarkable 2 is probably among the most affordable hardware around for such a purpose and the most open one with SSH access right onto the device, but you would have to implement the whiteboard-part yourself and just treat it as a eInk-display that you need to program yourself most likely, so probably not suited for your usecase? You could possibly build something with https://github.com/rien/reStream , but you would still have to build a substantial part of what you want yourself.
Maybe this works for you: https://github.com/fenollp/reMarkable-tools
