Description。The SparkFun TFT LCD Breakout is a versatile， colorful， and easy way to experiment with graphics or create a user interface for your project. With a 4-wire SPI interface and microSD card holder， you can use this breakout to easily add visual display/interface capabilities to a project as well as providing all the storage you might need for multimedia files.。To get started with this breakout， you will need an Arduino compatible microcontroller of your choice - we recommend something with extra RAM like the SparkFun Thing Plus. The breakout can be powered with either 5V or 3.3V. The microSD card holder is connected to the same SPI bus as the display which keeps the required pin count low and exists to relieve the burden from your microcontroller's poor memory due to having to store hundreds of images of cats， or really whatever you want to keep there. We have also gone ahead and tricked out the SparkFun HyperDisplay library with a driver made especially for this breakout!。Out of the box， the SparkFun TFT LCD Breakout will come with a large backing PCB that makes it easy to securely mount the display in a project. If you need a more flexible solution you can remove the display module， snap off half the backing board， and then re-insert the display module. When this is done you'll be left with the bare minimum frame around the display to more seamLessly integrate with your project.。Get Started With the SparkFun TFT LCD Breakout Guide。Features。128×160 RGB pixels。Up to 18 bit configurable color depth。2x PWM controllabele LED backlight。microSD Card Slot。V-Score for Minimal Footprint Setup

Description。The LIDAR-Lite v4 LED sensor is the next step in the LIDAR-Lite line. A small， lightweight， low-power optical ranging sensor. It's the first to incorporate ANT profile wireless networking technology into an optical sensor. Its built-in nRF52840 processor means that developers can create custom applications， or be operated as a stand-alone device right out of the box by using the preloaded stock application.。Like the LIDAR-Lite v3 and LIDAR-Lite v3HP sensors； it can also be directly connected to an external micro-controller running a custom user application. As such， it provides a highly adaptable option for OEM and maker applications in robotics， Internet of Things， and unmanned vehicles ― or any application where an ultrasonic sensor might otherwise be used. It's perfect as the basic building block for applications where wireless capabilities， small size， light weight， low power consumption and high performance are important factors in a short-range， 10-meter， optical distance measuring sensor.。The LIDAR-Lite v4 requires an external 5VDC power source and soldering is required. This Time-of-Flight ranging module uses a LED and optics for ranging. It does not use a laser； therefore， it is inherently eye-safe under normal usage.。Features。Resolution：1 cm。Measurement repeatability：As measured indoors to a 90% reflective target。1 cm is equivalent to 1 standard deviation。Using "high accuracy" mode， with averaging：+/- 1 cm to 2 meters。+/- 2 cm to 4 meters。+/- 5 cm to 10 meters。Range：5 cm to 10 meters(as measured from back of unit)。Update rate：I2C = >200 Hz typical。ANT(R)= up to 200 Hz to a 90% target indoors at 2m in normal operating mode。Interface：I2C or ANT； user configurable for SPI using the Nordic SDK。Power(operating voltage)：4.75 - 5.25 VDC。Current consumption：2mA idle， 85mA during acquisition。Operating temperature：-20 to 60° C。LED wavelength：940 nm。Beam divergence：4.77°。Optical aperture：14.9 mm。Unit size(HxWxD)：2.1"×0.8"×0.9"(52.2×21.2×24.0 mm)。Weight：14.6 g(0.5 oz)
