Evaluation Board for MLX90129


The EVB90129 is an assembled printed circuit board that simplifies evaluation of the MLX90129 sensor tag integrated circuit (IC) and to facilitate the development of wireless sensor applications based on the MLX90129.

The EVB90129 was developed to demonstrate a wide range of applications, from fully passive sensor tag operation to complex data logging. Each of its elements can be reconfigured by means of jumpers.

The evaluation board can be powered either by an external voltage supply, the on-board battery or the electromagnetic field from a radio-frequency identification (RFID) reader.

In addition to the internal temperature sensor of the MLX90129, the EVB90129 embeds 3 external sensors: light, temperature and potentiometer to demonstrate the flexibility for measurement of a variety of physical quantities. The custom prototyping area allows users to integrate their own sensor or circuit into this evaluation board.

The EVB90129 is capable of storing 128 kilobytes (KB) of data in the SPI EEPROM memory connected to the MLX90129.

The EVB90129 can be accessed and controlled through a contactless (RFID) or a contact (SPI) interface. The RFID access to the MLX90129 and the related commands are compliant with the ISO15693 standard. The SPI and other digital inputs/outputs from the MLX90129 are connected to an 8-pin connector of the EVB90129. This allows easy connection to a microcontroller.
