Description。The Mountable MI：pro is a simple and compact protective case for the micro：bit. This case has been specifically designed with portability and expansion in mind and is compatible with both the original micro：bit V1 and the micro：bit V2. These cases feature a three-layer construction style with ability to wall-mount the whole assembly onto any surface you want while still providing access to all buttons and ports on the micro：bit. Though these cases do feature wall-mountable tabs， the biggest benefit of using a case is to not accidentally short out the pads on the back of the micro：bit.。Construction is simple， requiring only a small flathead screwdriver， and involves layering each plate on top of one another around the micro：bit and screwing it into place. Luckily， the MI：pro case enables easy access to the edge pins at the bottom of the micro：bit， allowing it to still be plugged into an edge connector found on many of our carrier boards. The only board that cannot be used in conjunction with the MI：pro case is the SparkFun gamer：bit due to its edge connector being located in the center of the board.。Note：The MI：pro case only includes the parts found in the Includes Tab. This case does NOT include a micro：bit， power source or mounting screws. These items will need to be purchased separately.。Features。Dimensions：Length(minus the mounting brackets on the side)：65mm.。Length(with the mounting brackets on the side)：91mm.。Width：37mm.。Depth(without screws)：9mm.。Depth(with screws)：14mm.。Provides excellent protection to the BBC micro：bit whilst allowing access to the bottom pins.。Full access to the A and B buttons on the BBC micro：bit.。The mounting points allow you to fix the micro：bit to a surface for sturdy and more permanent installations.。Full access to pins and connections including the micro USB connector.。Clear case material shows the on-board LEDs in perfect clarity.。The case is compatible with versions 1 and 2 of the micro：bit.

Description。The SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options including SMA. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver， meaning it can receive signals from the GPS， GLONASS， Galileo， and BeiDou constellations with ～1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions increasing， precision and decreases lock time； and thanks to the onboard rechargeable battery， you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally， this u-blox receiver supports I2C(u-blox calls this Display Data Channel)which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.。The NEO-M9N module detects jamming and spoofing events and can report them to the host， so that the system can react to such events. A SAW(Surface Acoustic Wave)filter combined with an LNA(Low Noise Amplifier)in the RF path is integrated into the NEO-M9N module which allows normal operation even under strong RF interferences.。U-blox based GPS products are configurable using the popular， but dense， windows program called u-center. Plenty of different functions can be configured on the NEO-M9N：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library!。The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start(～24s)to a hot start(～2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.。This product requires an antenna：Be sure to check out the related products/hookup accessories and pick a suitable SMA antenna for your project.。The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
