These shrouded, 5-pin JST XH-style male connectors have straight leads. They can be used with female JST XH-style connectors, and they also work with other many other 0.1″-pitch female connectors, such as Pololu's female premium jumper wires. They are sold in packs of two units.
The QTR-1A reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following. The reflectance measurement is output as an analog voltage. This sensor is sold in packs of two units.
This is a 12V normally closed solenoid valve with no polarity distinction. It is normally closed until powered on. You can implement real-time water flow control with our water flow sensor. It can be widely used in automatic agriculture, fisheries and other projects that require water flow control. The direction of value terminals can be adjusted according to demand. The unit has stable performance, reliable quality, high sensitivity and other advantages. The product has a protection index of IP00 and can withstand 2.0 Mpa static pressure. A high quality stainless steel spring and material give it a lifetime of no less than 200000 cycles (If used 100 times per day, this will allow for more than five years of life).
These 17 mm long aluminum adapters convert a 4 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
These 20 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
These 17 mm long aluminum adapters convert a 3 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels.

Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn’t know how? Well, here’s how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the ¾" threaded inlet and it will interrupt the flow until 12V is applied to the fast-on connectors on the solenoid.
These 35 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
These side-entry screwless terminal blocks have a pitch of 0.1″ (2.54 mm). Each block has four spring terminals that automatically grip the stripped ends of inserted 26 – 18 AWG wires, allowing for easy, temporary connections to your PCB, and units can be combined to make longer blocks. They are rated for 150 V, 2 A (UL) and ship in packs of two.
