* nRF9160 tech specs provided from the nRF9160 Product Specification
Here are the elctrical specifications for the nRF9160 Feather. Most of the specifications here are based on the nRF9160 Product Specification. You can get the latest version of the nRF9160 Product Specification here. All previous versions can be found here.
- Output voltage: 3.3V ± 0.3V
- Max output current: 750
- Active sleep current < 10µA @ 3.6V¹
¹ Current above 4.0V increases significantly due to the switching regulator design. We recommend using single cell Lithium batteries or providing external power <= 4.0V
Pin Ratings (MD/A0-A5/D0-D8/TX/RX/CIPO/COPI/SCK/RST)
- Max input voltage: 3.6V
- Max input voltage: 6.5V¹
¹Enable pin is active high.
External Power Supply
The nRF9160 Feather can be powered via battery or USB. See below for the specifics for each power source
- Operating range: 5V ± 0.2V
- Current requirements: >500mA
- Battery type: LiPoly
- Operating range: 2.8-5.5V
- Current/power rating: Able to support at least 2W of power
- Battery capacity: > 300mAH²
- Charging current: 294mA ± 10%
²Batteries below this capacity are not recommended nor supported.
Note: with charging circuit disabled (short JMP2) any input source up to 6.5V is supported.
The U.FL port on the nRf9160 Feather is to be used with an active GPS antenna only.
- Antenna supply voltage: 3.3V ± 0.3V
- Antenna current rating: 15mA
The port works with most U.FL based active antenna parts. The nRF9160 Feather has been tested and verified with the following parts:
|ACTPAT182-01-IP||Inventek Systems||Link||Offered as an addon|
The nRF9160 Feather has been tested with these approved antennas. They're chosen specifically to match the FCC requirements as indicated here.
Only tested antennas are supported. If you choose to use a different one, proceed at your own risk!
