This 4A capable PowerBoost 1000 can turn almost any battery voltage below 5.5V into a steady 5.2V to power your USB devices.
This 224:1 gear motor is very comparable to a hobby servo for power, at a fraction of the cost!
We had Grand-Wing Servo supply us with an inventory of their modified GWS05 servo! It's a servo without pcb - all brawn, no brains!
This output gear changes the GM4 from continuous rotation to limited rotation.
The GM6 is a baby version of our popular GM2 gear motor.
The GM7 is a baby version of our popular right-angle drive GM3 gear motor.
This 143:1 gear motor is much like the GM2 gear motor but runs at nearly twice the speed. Great for robots needing speed over torque!
This 143:1 gear motor is much like the GM3 gear motor but runs at nearly twice the speed. Great for robots needing speed over torque!
A High-Efficiency (HE) 3V DC motor coupled to a 228:1 gearbox give you a very useful low-power gearmotor!
Need a gear motor and wheel? Get this convenient package, and save! Complete with a GM2/3/8/9/17 gear motor, a wheel with a molded-on tire, and mounting screw.
Here by popular demand, and brought to you only from Solarbotics! The pager gear motor is geared 81:1 spins at 233 RPM and draws 13mA (118mA stall) at 3V giving 2.3in*oz.
Small, speedy, and all-metal construction!
Just slightly faster than the original Sanyo GM12, and a wee bit less torque - a suitable replacement!
A bit slower than the GM13, but less current consumption. Less expensive, too!
A replacement for the GM14 that has more torque!
Advanced prop designers and industrial engineers have asked us for more horsepower and that's what we've delivered with the Prop-SX.
Want a small, quick precision metal gear motor?
This amazing little motor contains a 25:1 planetary gear reduction on top of a pager motor, all under 6mm diameter! It's smaller than many regular pager motors!
These new, factory-fresh pager motors come ready-to-run: no eccentric weight removal necessary like on surplus pager motors!
The GWS S03N servo is a good, solid workhorse if you have a need for inexpensive reliable servos.
This NPN transistor is similar to the TR3904, but can deliver higher maximum current at better efficiency ratings.
This PNP transistor is similar to the TR3906, but can deliver higher maximum current at better efficiency ratings.
TR3904 NPN small signal transistor, as used in most basic solarengine designs.
TR3906 PNP small signal transistor, as used in most basic solarengine designs.
This low-voltage N-channel FET is great for powerful solarengine designs.
