These picture show only early design/prototype and what you will get may be somewhat different (better).

This project has a 50A meter but will be wired to handle 40A. It will Measure voltage from 0VDC to100VDC. In this configuration, the measuring voltage will be from 5V to 30V. It has a minimum resolution of 0.1V. It requires less than 20mA current. The Operating voltage is from DC 4.5V to 30V which will be supplied by the Buck converter (included). The buck converter operating voltage is 4.5 to 30V and can output 0.8V to 20V, so even a 5VDC test voltage will work. It will use Anderson Powerpole connectors, so it will be easy to use and can be left in a circuit.

Useful applications will be to monitor voltage and current use in transmitters up to or higher than 100 Watt output. 12V accessories from a car, including mobile transceivers. Powered wheelchair power draw up to 40A. Almost any project the use 5VDC to 30VDC.
