+/-18V ISOLATED DC-DC CONVERTER DUAL SUPPLY OUTPUT FROM USB 5V POWER INPUT

This is a mini DC-DC converter with dual output from single 5V DC supply or USB power source (e.g., +/-18V from 5V/USB). The mini board will fit into small space and perform with high efficiency. Basically, the circuit transfers power from 5V/USB to the output side +/-18V with high isolation, without a direct connection between 5V/USB power and output. The power …

Raspberry pi pico Signal Processing Examples – CircuitPython

N.B. this is new and still being tested. The following Python samples demonstrate several single-channel filters for processing sensor data. The filter functions are purely numeric operations and should work on any Python or CircuitPython system. This supports offline testing, as they can be debugged and evaluated on a normal desktop computer. The code is …
