Handheld RNode


SKU: rnv21h Category:

This is the version of the Handheld RNode design. It's a portable, durable and higly functional unit that can serve many different purposes. See the RNode page for more information.

If you can, please build this device yourself, instead of buying it from me! Check out the Handheld RNode Build Recipe, or an online copy of the RNode Bootstrap Console.

The case is made from durable PETG, and the pictured model is the normal sized case in the Anthracite Grey color. This is the default configuration, but custom colors and size configurations can be made to order.

For custom orders, both the colors and case size can be chosen. The minimum order quantity for custom orders is 10 units. There is three sizes of the case to choose from:

  • A normal case with battery compartment, fitting 700mAh batteries
  • A large case with a battery compartment, fitting 1200mAh batteries
  • A slim case with no battery compartment

Please note that the device does not ship with a battery installed. You can use any standard 3.7v, single-cell lithium-polymer battery with a 1.25mm JST connector, provided it will fit in the battery compartment (see the exact dimensions below).

A compact and basic antenna is included with every device for free. It will work fine for testing and basic use, but does not offer very high performance. You can add one of the other antennas from the shop to your order, or use any suitable antenna that fits a standard SMA connector.
