This will return the current\nin amps.\n- **Range**: Select the maximum current you want to measure. Select this as\nclose to the maximum you wish to measure as possible.\n- **Load VCC Select**: This selects how you would like to power the load under\ntest. The options\n  - Power Supply: Use the input from the power supply that is powering the\n  measurement circuitry to also power the load.\n  - 3V3: Use the onboard regulated 3.3 V rail to power the load.\n  - Test Input: Use the external test input to power the load.\n- **To Load**: Connect to VCC or the signal you wish to measure.\n- **GND**: A set of ground pins for convenience.\n\nErrata\n------\n\nThe 300 mA range doesn't seem to work on v3.\n\n----\n\nV2 Notes\n--------\n\n\u003cimg src=\"media/current_sense_v2.jpg\" width=\"30%\"\u003e\n\nYou need a power selection jumper. You usually want to power the board externally,\nin which case you'll want the jumper in the high position as pictured.\n\n - Connect external power (3.3-6V) to the EXT header at the top right.\n   I usually also connect the external power to the GND header up here.\n - Connect the power supply for your target to VIN header.\n - Connect the VCC of your target to the VCC header\n - Connect the GND of your target to the GND header.\n   I usually connect target GND to the GND header at the bottom, whose label is\n   occluded by the screw.\n - Hook the scope probe to the test point at the top left (and GND anywhere)\n \nThe rest of the board is the same idea as above. Choose a range, measure voltage,\ndivide by the number on the board, get amperage.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flab11%2Fcurrentsense","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flab11%2Fcurrentsense","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flab11%2Fcurrentsense/lists"}
