*Skywire current requirements will vary between different modem models. Modems will use more current in low

signal conditions (poor RF reception).

2.5 Power Requirements

The adapter requires a +5VDC input to J5 in order to power the Skywire Modem.

The adapter can not be back powered by the Raspberry Pi, but the +5VDC input

from J5 can power any attached Raspberry Pi.

Nimbelink recommends using a +5VDC 3A supply, such as CUI's

​SWI18-5-N-P6​,

to ensure enough current is available for the Skywire and the Raspberry Pi

during high current loads.

2.6 Raspberry Pi Compatibility

NimbeLink’s Skywire Raspberry Pi Development Kit has been designed to be

drop in compatible with the following Raspberry Pi models:

-

Raspberry Pi 3 Model B

-

Raspberry Pi Compute Module 3 I/O Board.

2.7 Antenna Specifications

For optimum performance, a dipole antenna, such as a Taoglas

​TG.30.8113

antenna, is recommended.

2.8 Features

Nimbelink's Skywire Raspberry Pi Adapter is designed to be a low cost,

adaptable cellular gateway for the Raspberry Pi development platforms. The

adapter enables diverse connectivity options by including a Skywire Cellular

Modem socket for cellular/GPS connections, allowing users to use any of

Nimbelink's 2G, 3G, or 4G Skywire modems.
