Ethernet In An Inch
Need an NDAA Compliant version? Check out SwitchBlox Nano NDAA.
SwitchBlox Nano is the smallest ethernet switch currently available, with three 10/100MB ethernet ports in the size of a quarter coin.
With an overall size of 25.5mm (1 inch) by 25.5mm (1 inch), SwitchBlox Nano is designed for truly space-constrained applications that need compact, robust ethernet connectivity.
SwitchBlox Nano runs from a wide input voltage of 5 to 45V and outputs an auxiliary 5V, 1A output. These features make SwitchBlox Nano ideal limited internal volumes.
Plug and play network switch
As an unmanaged network switch it works straight out the box, all you need to do is...
- Apply a 5 to 45V DC supply.
- Connect your devices using the included cable set.
- It will automatically begin forwarding packets, no coding or setup is needed.
By utilising surface mount transformers, and a dense layout we've squeezed three ethernet ports into a 1x1 inch square. SwitchBlox Nano boards are fully tested to perform data rates of up 100MB/s.
We use Molex Picoblade connectors on all our boards to keep them tiny. All boards ship with a cable set included, which consists of...
3 x PicoBlade to RJ-45 300mm (SKU: BB-PBRJ1-4-0.3)
1 x PicoBlade to bare wires 300mm (SKU: BB-PBTL1-4-0.3)
SwitchBlox Nano has an STM32 microcontroller onboard, allowing basic switch management functions such as VLAN (port and tag based) and Port Mirroring.
This allows the creation of a very small traffic sniffer or VLAN tag stripper.
To configure this, read our software guide or get in touch for support.
SwitchBlox Nano Harwin 1.27mm (Board Mount) Variant
We offer a board-mountable version of SwitchBlox Nano that uses board-mount connectors for direct mounting onto a PCB. This board uses Harwin M50-3530442 connectors instead of the standard Molex PicoBlade connectors. The DXF profile and 3D model of this part can be found in the links below. Documentation for this board mount version is below.
