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 newer chips are really easy to use. All the chip really needs is the usual soft reset circuit (10K resistor + 100nF cap) and a 100nF cap on each power pin. Read through the readme's here: https://github.com/SpenceKonde/DxCore
