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...

1. Apply a 5 to 45V DC supply.
2. Connect your devices using the included cable set.
3. It will automatically begin forwarding packets, no coding or setup is needed.

Dimensions

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.

INCLUDED CABLES

We include everything you need to make this board work out of the box. Each board ships with:

3 x Molex PicoBlade to RJ-45, 4 way, 0.3 meter (Data cables)
SKU: BB-PBRJ1-4-0.3

1 x Molex PicoBlade to Tinned Leads, 4 way, 0.3 meter (Power cables)
SKU: BB-PBTL1-4-0.3

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.

Covered under the BotBlox Supply Guarantee Program

This board is covered by our supply guarantee, which guarantees availability and low lead times until at least 2028. Read more about the BotBlox Supply Guarantee Program.

Need NDAA compliance?

We offer a fully NDAA compliant version of this hardware, simply select the option at the top of the product page.
Our NDAA version has the same design as the base product, but uses a supply chain based outside of the four adversary countries listed in Executive Order EO13981 (these are Iran, Russian, China and North Korea). 

The NDAA compliant version is part of our first stage to move away from a Chinese based supply chain, to meet the needs of our customers who must ensure NDAA and EO13981 compliance in their UAS systems. Read more about our efforts here.

• The boards are manufactured in Thailand
• The active chips are sourced from either Digi-Key, Mouser, or directly from our European distributors
• The passive chips are sourced only from Digi-Key or Mouser
• All passive components are sourced from Digi-Key or Mouser.

This allows our customers to build NDAA and EO13981 compliant UAS systems with no extra work. We are able to provide full Certificate of Conformities, Bill of Materials and Traceability statements to ensure this. Please note, there is no design difference between this board, and our standard SwitchBlox. 

The NDAA compliant version can be used to build BlueUAS compliant UAS systems. Read more about this here.

Custom Cables

All our boards are shipped with the required 0.3 meter power and data cables included, so you do not need to purchase extra cables. However if you need custom cable lengths for your application, you can order those here.
