# Connection to Host CPU

The boards can be connected in 2 ways with different corresponding jumper settings underneath the board:

- UART mode (default mode)

![UART Mode](docs/Default_UART.jpg)

- SPI mode (requires resoldering of jumpers)

    - With CS on pin 9 ![SPI mode with CS on pin 9](docs/SPI_CS_option_1.jpg)

    - With CS on pin 10 ![SPI mode with CS on pin 10](docs/SPI_CS_option_2.jpg)

# Metering  modes

Using the MMD jumper various metering modes can be selected as specified by the datasheets.

# Connection to Voltage/Current samplers

The ATM90E26 can acquire 1 voltage and 2 current waveforms to perform energy measurement.

- Voltage sampling using step-down transformer (9V-12V) and voltage divider

- Current sampling using CT with multiplier resistor
