Hi,

We here have purchased the “harwin variant” of the SB Nano.  
It seems there is an inductor (47uH) that is much larger in real life compared to the 3D model.  
Using you recommended mating 3.6mm PCB connector will likely mean that this inductor will  
not allow the board to fully seat against the connector housing.

Is it possible to use an inductor with a lower height? We do not use the 5V output.

Looks like that’s an error on our 3D CAD. Sorry about that, we’ll get that fixed asap.

The solution is to use a mating part on your board, such as…

> **[1.27mm (.05") Pitch Vertical Socket - M50-3030442 | Harwin](https://www.harwin.com/products/M50-3030442/)**
>
> 1.27mm (0.05") Pitch PCB Connector - Archer M50 Board-To-Board | 4 Pos. Female SIL Vertical Throughboard Conn. | M50-3030442

> **[1.27mm (.05") Pitch Vertical Socket - M50-3140445 | Harwin](https://www.harwin.com/products/M50-3140445/)**
>
> 1.27mm (0.05") Pitch PCB Connector - Archer M50 Board-To-Board | 4 Pos. Female SIL Vertical SMT Conn. | M50-3140445

> **[1.27mm (.05") Pitch Vertical Socket - M50-3130445 | Harwin](https://www.harwin.com/products/M50-3130445/)**
>
> 1.27mm (0.05") Pitch PCB Connector - Archer M50 Board-To-Board | 4 Pos. Female SIL Vertical SMT Conn. | M50-3130445

This adds some vertical to the board to prevent the inductor from conflicting with the board.
