Working Voltage : 5V(DC)
Static current: Less than 2mA
Output signal: Electric frequency signal, high level 5V, low level 0V.
Sensor angle: Not more than 15 degrees.
Detection distance: 2cm-450cm.
High precision: Up to 0.3cm
Input trigger signal: 10us TTL impulse
Echo signal : output TTL PWL signal
use IO port TRIG to trigger ranging. It needs 10 us high level signal at least
Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
If there is signal returned, output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
Testing distance =duration of high level*sound velocity(340m/s) / 2
Mode of connection:
VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.
SainSmart UNO R3 ATmega328P Development Board + Free USB Cable Compatible With Arduino
Features * ATmega328-AU microcontroller * Input voltage - 7-12V * 5V Electric current: 500MA * 3.3V Electric current: 50MA * 14 Digital I/O Pins (6 PWM outputs) * 8 Analog Inputs * 32k Flash Memory * 16Mhz Clock Speed Main Changes from the Old Version * 1. TWI interface and the IOREF in the top and bottom connectors. This change keeps the board 100% compatible with the current boards and shields, but adds possibilities for new shields. * 2. Reset button moved from center of board to corner near USB connector. This is great; makes it much easier to access with a shield on. * 3. Larger heatsinking copper area for the LM117 regulator * 4. Uses an Atmega16U2 instead of the Atmega8U2 on the previous version. Opens up more possibilities for USB apps! * 5. Arduino can only work at 5V voltage. When it comes to 3.3V Level module, IO can't be connected to it. The Level should be changed, like the SD card, Bluetooth module and so on. Sainsmart UNO R3 can work at 3.3V voltage by switching on the button. At this time, IO port is 3.3V and it can work with 3.3V Level module. Package Content 1 x UNO R3 1 x USB cable
IEIK UNO R3 Board ATmega328P with USB Cable for Arduino - Compatible With Arduino UNO R3 Mega 2560 Nano Robot
Color: uno R3 blue
Product Features: 100% Brand New Difference between UNO R3 2012 and UNO 2011 1. Pin of changes: next to the AREF pin both I2C-pin (SDA and SCL, just Analog 4 and 5 of the copy, not the additional I2C interface), plus the two next to the RESET pin, one IOREFallow expansion board voltage onboard, this pin expansion board just told the onboard voltage (such as UNO 5V, can be seen as the power pins copy, does not provide the level pull), the other is laterScratch placeholder pin. 2. More stable RESET circuit. The RESET key position has changed, which has been moved to the corner near the USB interface board, more convenient and press. 3. The ATmega16U2 instead 8U2, and that does not mean that the 16K flash of UNO R3 make your code run faster, this update is a service of the USB interface chip, theoretically It UNO can simulate USB the HID, such as MIDI / Joystick / Keyboard. Microcontroller: ATmega328P Operating Voltage: 5V Input Voltage (recommended): 7-12V Digital I/O Pins: 14 (of which 14 provide PWM output) Analog Input Pins: 6 DC Current per I/O Pin: 40 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader SRAM: 2 KB EEPROM: 1 KB Clock Speed: 16 MHz Package includes: 1 x IEIK UNO R3 Rev3 Development Board 1 x USB Cable Note: We are using a brand-name components, more efficient, more stable, better prices.
iGuerburn Clear Transparent Case for Raspberry Pi 3 Model B/ Raspberry Pi 2 Model B/ Raspberry Pi 1 Model B+ (B Plus) + Aluminum Heatsink (Transparent Logo)
Color: Transparent Logo
Main Features: *All ports accessible. *The case is constructed of PC material which has the advantages of good high temperature resistance, impact resistance. And you can put much pressure or weight on the case without danger of cracking. So it is more better than the ABS material or other materials. * The bottom of the case has two + shaped holes for mounting the case in a larger enclosure, to a wall, etc. *Light, clear and quite well made case for Raspberry Pi Model B+. *Two piece construction and very easy to snaps together. *The top panel is designed for easy access to the GPIO pins and easy to plug and remove anything you will be connecting to it. *Bottom ventilation design and allows sufficient air circulation. *There are 4 little stick-on rubbery feet to put on the bottom and keeps the case from scratching on the desk. *The case also comes with screws to secure the board to the case. *Enough room to add heat sinks Warranty: 1-Year warranty Package includes: 1 x Transparent Clear Case for Raspberry Pi 2/Model B+ 3 x Heat Sinks 4 x Screws 4 x Rubbery feet Note: Raspberry Pi 2 / Model B+ does not included
