ATM90E2X-DB

ATM90E2X-DB is an ATM90E26 demo board. It is used for the demo and testing of ATM90E26 (single-phase energy metering AFE chip), which can sample single-phase voltage and current, meter active/reactive energy and output active/reactive energy pulses accordingly, as well as measure parameters such as voltage, current, and power. The AFE control board - SAM4C communicates with and controls the AFE board, providing easy access to evaluate the energy metering chips. It is a single-phase energy metering board designed with Atmel’s ATM90E2x chip. It communicates with the AFE control board through the extended communication connector (J2).

• ATM90E26: single-phase energy metering AFE chip
• Voltage sampling: resistor divider network
• Crystal: 8.192MHz
