DescriptionLIDAR has never looked so good! This is the LIDAR-Lite v3HP， a compact， high-performance optical distance measurement sensor from Garmin(TM). The LIDAR-Lite v3HP istheideal optical ranging solution for drone， robot， or unmanned vehicle applications. Each sensor is housed in a durable， IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz(where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3(that's 65mA as opposed to 105mA while idle， and 85mA instead of 130mA while acquiring).Each LIDAR-Lite v3HP has a range of 1m to 40m and features an edge-emitting， 905nm(1.3 watts)， single-stripe laser transmitter， 8m Radian beam divergence， and an optical aperture of 12.5mm. This version of the LIDAR-Lite still operates at 5VDC(6V max)with a peak power of 1.3W and still possesses an accuracy of +/- 2.5cm at >2m. On top of everything else， the LIDAR-Lite is user-configurable， allowing adjustment between accuracy， operating range and measurement time and can be interfaced via I2C or PWM with the attached 200mm cable.Note：CLASS 1 LASER PRODUCT CLASSIFIED EN/IEC 60825-1 2014.

DescriptionThe 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. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.The NEO-M9N GPS Breakout can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system.

DescriptionAdd another eight pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two I2C pins which can be shared with other I2C devices， and in exchange gives you eight general purpose pins. You can set each of eight pins to be input， output， or input with a pullup. There's even the ability to get an interrupt via an external pin when any of the inputs change so you don't have to keep polling the chip.Use this chip from 2.7-5.5V(good for any 3.3V or 5V setup)， and you can sink/source up to 20mA from any of the I/O pins so this will work for LEDs and such. Team it up with a high-power MOSFET if you need more juice. DIP package means it will plug into any breadboard or perfboard.You can set the I2C address by tying the ADDR0-2 pins to power or ground， for up to eight unique addresses. That means eight chips can share a single I2C bus - that's 64 I/O pins!Features8-bit remote bidirectional I/O portHigh-speed I2C interface(MCP23008)Hardware address pinsConfigurable interrupt output pinConfigurable interrupt sourcePolarity Inversion register for input port data polarity config.External reset inputLow standby current：1 μA(max.)・ Operating voltage：1.8V to 5.5V @ -40℃ to +85℃ I2C @ 100 kHz SPI @ 5 MHz2.7V to 5.5V @ -40℃ to +85℃ I2C @ 400 kHz SPI @ 10 MHz4.5V to 5.5V @ -40℃ to +125℃ I2C @ 1.7 kHz SPI @ 10 MHz
