With its PC application, it can be used to monitor power consumption of USB devices, ambient temperature variation and external voltage, as well as to measure values for through-hole resistors and capacitors. It also includes an EEPROM, a GPIO expander and a PIC16F1509 pre-programmed microcontroller which can be configured to alert the user in case of specific event types, such as temperature exceeding a certain value.</span> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li><span style="font-family:arial, helvetica, sans-serif;font-size:10pt;">Real-time monitoring and logging
