Measuring MCU current
Cut trace jumper J14 is provided to isolate the power supplied to the KV11 MCU. To measure the
current consumed by the MCU you can cut the trace on J14 and place a milliamp measuring DMM
across the J14 header pins. Alternatively, you can populate the 10 Ohm R126 and place a voltage
measuring DMM across the J14 header pins. The current will be = to the V/R126 value.
