MLX90121 Evaluation Board
4 Guidelines
This chapter describes all connections and jumpers available on the EVB90121 circuit to be able to use it in
the most efficient way.
4.1 Power supply
• The circuit can be supplied with a standard DC supply block (transformer or switch mode power supplies)
connected to the jack connector J1. The input supply can be selected from 6 to maximum 9 volts DC to
avoid permanent damage of the evaluation board.
• The internal power supply of the board can be selected between 3 Volts and 5 Volts DC by changing the
position of the jumper J3.
4.2 Antenna connection
• The SMA screw connector JP1 allows the connection of a 50-ohm antenna. The matching network is
adjusted with CV1 capacitor on a prefect 50-ohm load. This will give maximum power up to 200mWatt to
the connected antenna.
4.3 Connection to a microcontroller
• All digital Inputs/Outputs of the MLX90121 device are available on the JP2 connector. This allows easy
connection to a microcontroller. Following table is the description of JP2 connector.
