nRF9151 Micro Breakout

The world's smallest Nordic nRF9151 full pin breakout. Designed for developers who want direct access to every nRF9151 pin without the constraints of a full development board.

Key Features

  • Smallest nRF9151 breakout available
  • 14 × 20.8 mm form factor
  • Hand-solderable 1mm pitch castellated pads
  • Single-sided — easily added to custom PCBs
  • Dual U.FL connectors (GPS and cellular)
  • Separate power connectors for VDD, VDD_GPIO & GPS LNA power
  • 1 PPS (pulse per second) pin broken out from GPS
