1 Description
The development kit provides the needed information and components to evaluate the current sensors
MLX91205 and/or CSA-1V. The main goal is to show the functionalities and the features of the parts in a
simple and effective way, without the need of investing precious time and money for develop design.
The kit includes:
1 MLX91205LB mounted on PCB_EC01
1 MLX91205LB mounted on PCB_EC02
1 separate MLX91205LB
3 separate MLX91205HBs
1 separate PCB_EC01
1 separate PCB_EC02
2 shields U_12
The kit does not include a busbar.
