Ordering information Product Option Comment EVB73290-A 433-C Evaluation board 433MHz General description The EVB73290-A is an assembled printed circuit board that simplifies the evaluation of the MLX73290-A device and facilitates the development of wireless applications with this product. It is connected to a specific SPI to USB adaptor for programming the MLX73290-M device through the USB connection of a computer. The EVB73290-A is delivered with GUI-based evaluation software to easily and quickly configure the device. The MLX73290-A device combines a highly integrated Radio Frequency transceiver for long range, high speed communication and a 3 dimensional low frequency interface (3DLF) for low power wake-up. This unique combination makes the MLX73290-A suitable for applications requiring a very low power wake-up function together with long range, high speed RF feedback. 390127329002 Page 1 of 41
