Troubleshooting
Channel A and Channel B Direct Connection
The Non-Invasive Current Sensor board is designed to work with a current transformer with a CT ratio of 2000:1 connected to the 3.5mm TRRS jack. The through-hole connections to Channel A and B do not have any extra current transformation ratio integrated and operate at a 1:1 ratio. As a result, AC loads connected to these pins should not exceed 100mA.
ADE7953 SPI Interface
The Non-Invasive Current Sensor board design only supports the ADE7953's I2C and UART interfaces as it does not break out the SCLK and CS pins for communicating over SPI. While not supported by SparkFun, if you need to use the ADE7953 over SPI you can adjust the SCLK and CS jumpers to enable SPI and then carefully solder to the SCLK and CS solder jumper pads to make those connections.
