Hello wonderful people at Particle community,
In the past, I have used a USB adapter to power our Particle-based product. However, customers desire the ability to plug our product directly into a wall outlet. Hence, I have started exploring options to integrate an AC-to-DC converter.
While I have been able to find numerous resources for the circuit design and even a few board-mount module options, I am yet to find a reliable NEMA connector that could be soldered on the board. Specifically, I am looking for the plugs shown here in the white circle.
Does anyone know what they are called? I checked with Digikey tech engineer and they couldn’t help. I have seen them on numerous products like USB adapters, smart outlets, so they cannot be custom-made I feel.
In addition, as can be seen in the picture, the power connectors are on a separate PCB (black rectangle) than the digital part of the board and it may be a common practice for scaling reasons. If anyone has gone done this path, could you share good practices for power supply design (EE, regulatory, scaling) in a connected product?
Your inputs and help are much appreciated.
