Current Switch PCBA

A customer required a custom PCBA allowing for measuring and interrupting current for the development and prototyping of an industrial product. This PCBA would allow the customer to perform basic tests of their concept product with minimal investment and using the MCU platform they are familiar with. The customer’s specifications were:

• 3x Optoisolated Digital Inputs
• 1x Hall Effect Current Sense Input
• 3x Relay Outputs
• USB Powered
• Interface to Mbed Nucleo development board

​

The PCB was designed in Altium Designer and prototypes were assembled by Level Engineering
