Description。No， this isn't a tank tread， this is a 0.5m long Cable Carrier with 10x15mm bits composing its main body and two screw fasteners at each end for efficient mounting. Sometimes called a "drag chain，" each carrier can be used in projects with a large number of moving parts to protect internally installed cables， pipes， or tubes so they can be bent and moved while remaining protected. Cable carriers can most commonly been found in 3D printers and CNC machines but they can be used in any situation where you need cables or tubes to bend without risk of them being damaged or wearing out prematurely.。This specific cable carrier offers inner dimensions of 10mm(height)by 15mm(wide)， an outer width of 22mm， and a bend radius of 20mm. Additionally， these carriers are thin enough to fit into an Actobotics channel， making custom slide machines or other projects even easier to manage. Much like a chain， individual links can be added or removed to make custom lengths.。Features。Inner Bit Height：10mm。Inner Bit Width：15mm。Outer Bit Height：14。Outer Bit Width：22mm。Minimum Bend Radius：20mm。Reinforced Nylon Structure

Description。This is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.。This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!。The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.。SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.。Get Started with the RFM69HCW Hookup Guide。Features。Transmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm steps。Receive sensitivity：down to -120dBm at 1.2kbps。Modulation types：FSK GFSK MSK GMSK OOK。Bit rates(FSK)：1.2kbps to 300kbps。Voltage range：1.8V to 3.6V。Current consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)。Encryption：AES 128-bit(optional)。Packet buffer(FIFO)：66 bytes。0.8"×1.1"

。Description。Passive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.。PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.。Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal.
