Overview
This board enables easy connection of the PAC1954 to power sources and loads for power monitoring and energy metering using on board 4mOhm high side current sensing resistors. It has USB connection to PC and a GUI to display the data, as well as options to disconnect the PC and communicate directly with a different host controller. Measurement channels 1,2 and 3 are pre-populated to show demo currents and they can be switched to the external input sense resistors by moving two 0 Ohm resistors on each channel.
- 4 high side measurement channels with 4mOhm shunts routed with Kelvin connection
- I2C to USB bridge on board
- Demo square wave current generator on board
- Test header to measure the PAC1954 power consumption
- Test points on all pins of the PAC1954
Cannot load image!
