Features

The PIC32CXMTSH-DB board includes the following features:

• Residential (2 voltages and 2 currents) Smart Meter Demonstrator
• Dual Arm Cortex-M4F cores and energy metering AFE
• Voltage range measurement is from 90 Vac to 264 Vac. It can be extended to 291 Vac removing the power supply (U1)
• Current range measurement depends on the current sensor used and the configuration of the internal PGAs. The current sensor input channels come populated with 3.24Ω burden resistors for a current transformer (CT)
• Compliant with CT, Shunt or Rogowski Coil sensors
• Opto-Port interface compliant with ANSI C12.20 protocol for AMR
• Isolated access to metering pulses (Wh, VARh, A²h) by an Opto-Port and/or an isolated interface
• Flash memory for meter data storage and firmware update
• Battery-backed real-time clock and power supply monitor
• Custom smart meter 20-segment LCD and control buttons
• Isolated UART interface by USB bridge
• Interface for Xplained PRO and mikroBUS^TM standard add-on boards
• Safety case to handle the board without electrical shock risk
