Description。The CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage(VP)and the negative-going voltage(VN)is defined as hysteresis voltage(VH).。Features。Schmitt trigger action with no external components。Hysteresis voltage typ. at 0.9V at VDD = 5V， 2.3V at VDD = 10V， and 3.5V at VDD = 15V。Noise immunity greater than 50%。No limit on input rise and fall times。Standardised， symmetrical output characteristics。100% tested for quiescent current at 20sV。Maximum input current of 1μA at 18 V over full package temperature range； 100nA at 18V and 25℃。Low VDD to VSS current during slow input ramp

The new USB Tester Backback 2.0 brings many new features to the already very useful tool. We have worked hard over the recent months to bring most of the many requested features.。The USB Tester makes it easy to monitor the current and voltage of any USB device. It is inserted inline between your USB device and your power source or computer. This allows you to make sure you are getting a true 5V and to read how much power your projectdevice is using. For example、you can check which charger/cable allows your phone to charge the fastest. The base can be used with a Digital Multi Meter or with the Backpack、you can see the readout directly on the display. The default mode shows a graph of current usage、with the button cycling through the different modes.。The OLED Backpack can connect to a computer either using the Java app or the wizkers.io Chrome app. Both can graph and log the data which can be export as a CSV file. Wizkers is easier to setup and can handle firmware updates.。Features：Micro USB。Button Location on the front left。128x64 OLED Display。Voltage monitoring of the USB Data lines。Easier access to almost all the extra GPIO's。Separated voltage test points(Easier to attach test clips and avoid misplacing jumper)。Standard Dual Banana spacing 0.75in。Standard test probe sized test points。Firmware Features：Peaks。mWh and mAh tracking。Bar Graph of volts、watts and current。JSON for serial communications。Java App：Uses JSON over serial。Save as CSV。View max、min、avg on each graph。Specification：OLED。.96in。128x64。SPI。Supply：4.5v-5.5v。I/O：3.2v-5.5。8 Pin。PCB：26.7mm×25.4mm。Monochrome(WHITE)。Display Mode：Passive Matrix。Drive Duty：1/64 Duty。Active Area：21.744×10.864(mm)。Pixel Size：0.154×0.154(mm)。Pixel Pitch：0.17×0.17(mm)。2.0mm pitch(Might be breadboardable if you bend the pins out)(same pitch as Xbee)

Description。This is not your normal Passive Infrared(PIR)sensor! The SparkFun AK9753 Human Presence Sensor Breakout is a Qwiic-enabled， 4-channel Nondispersive Infrared(NDIR)sensor. Each channel has a different field of view， so not only can the AK9753 detect a human， but it can also tell which direction the person is moving. To make it even easier to use this breakout， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system. However， we still have broken out 0.1" spaced pins in case you prefer to use a breadboard.。The onboard AK9753 is a digital sensor giving you a 16-bit digital value over I2C. Each of the four sensors outputs the IR current in pico-amps. A PIR reading can vary from roughly -200(no human present)to 1500 when a human is detected standing in front of a given channel， but it varies due to environmental factors and other heat sources in view. We've written a full library to control the sensor and included examples showing how to output the sensor readings you need， making this breakout even easier to handle!。Note：The I2C address of the AK9753 is 0x64 and is jumper selectable to 0x65 or 0x67. A multiplexer/Mux is required to communicate to multiple AK9753 sensors on a single bus. If you need to use more than one AK9753 sensor consider using the Qwiic Mux Breakout.。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.。Get Started with the Human Presence Sensor Breakout Guide。Features。Qwiic-Connector Enabled。Quad infrared sensor module。16-bit reading on all four channels。Digital I2C Interface。Voltage：1.7V to 3.3V。Extremely low current：100μA
