3P Screw Terminal Block - 0.137"
$1.60 In StockThis terminal block is a great use for semi-permanent connections. Simply insert the wire and screw down the terminal to tighten the connection. This terminal block has a pitch of 0.137" (3.4798mm) where each contact is rated for 12A. Note: Colour may vary.
4mm to 4mm Flex Shaft Coupler
$9.20 In StockConnect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they're cut, they're a little springy in the X Y & Z linear axis but not in the...

UDB1005 Function Generator - 5MHz
$85.00 In StockThe maximum frequency for this function generator is 5MHz. The different types of waveform this function generator can create are sine, square, triangle, and sawtooth types. This function generator is quite good as it has an output impedance of 50ohm! The resolution is 10mHz which has both TTL sync output and 60MHz frequency counter.
HC-05 Bluetooth Shield
$21.95 In StockThe HC-05 Bluetooth Shield is an easy way to connect the Arduino to any Bluetooth device. The HC-05 Bluetooth Module is a v2.0+EDR (Enhanced Data Rate) Bluetooth which uses a2.4GHz radio transceiver with 3Mbps modulation.
2.1mm DC Barrel Splitter - 2-Ways
$6.10 In StockDouble up your power adapters with this wonderfully simple 2-way power jack splitter. All you have to do is connect a standard 5.5mm/2.1mm sized plug into one end, and behold, two identical plugs to use! We like the rugged molding on these adapters, and they're really handy when you have a project with multiple pluggable devices.
T8 Lead Screw - 300mm
$22.00 In StockThis is a T8 300mm lead screw and brass flange nut set which can be self-locking. The T8 lead screw is perfect for high torque requirements of transmission, such as the aixs for 3D printer. The lead screw also can carry larger load than the threaded rod.
8P SPST DIP Switch
$1.18 In StockDIP switch are very similar to slide switch in terms of functionality. However, DIP switches are made in DIP packages which than can be plugged directly to any standard breadboard!
66 x 33mm Solar Panel (8V 23mA)
$13.80 Out of stockOut of stockThis SCC3766 solar panel is made with epoxy-encapsulated monocrystalline solar cells which can generate a nominal 8V 23mA. The dimension of this solar panel is 66mm x 33mm.

$0.69 In StockThis is your standard tactile button with dimensions of 6x6mm. The height of this switch is 9mm.
EC11 Rotary Encoder with Switch
$8.25 In StockRotary encoders are used similarly to potentiometers. Theyโre different from potentiometers in that an encoder has full rotation without limits. This EC11 series uses 20 pulse/rev.
Quad Band Cellular Duck Antenna - SMA
$9.00 In StockThis is a fantastic find for SFE. A small, high-quality, quad-band, standard SMA terminated, cellular antenna.
MQ-6 LPG, Isobutane & Propane...
$8.70 In StockThis semiconductor gas sensor detects the presence of LPG, isobutane, and propane at concentrations from 300 to 10,000 ppm. The sensorโs simple analog voltage interface requires only one analog input pin from your microcontroller.
SPDT Rocker Switch
$1.50 In StockRocker switch are great for use as an ON/OFF button as it already has the ON/OFF symbol printed on it! This Rocker Switch is rated for 250VAC 6A with dimensions of 12x18mm.
I2C Controlled LCD Shield
$29.00 In StockThis new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the Blue & White 16x2 LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to control the backlight for a total of 7 pins. That's almost half of the pins available on a classic Arduino!
