We received order 1J200000 this morning from Ralf in Germany! However, it turns out that because of a one-time database screwup, this was not actually our 200,000th order (thanks, Paul). We received that one a few minutes later when Alex from Iowa placed order 1J200008. To celebrate, we included a special gift with both of these orders: a prototype of the new Zumo robot we expect to release this month. Congratulations to Ralf and Alex! For everyone else, keep an eye on this blog for more information on our new Zumos, and thank you to all our customers for helping us get to 200k orders.
This new stepper motor bracket is designed to work with typical NEMA 14-size stepper motors, including all of the NEMA 14 stepper motors we carry. It is made from 2mm-thick black anodized aluminum, and like the larger NEMA 17 bracket we released earlier this year, it features slot cutouts to allow for a variety of mounting options.

Sharp GP2Y0A51SK0F Analog Distance Sensor 2-15cm with wires soldered directly to the sensor PCB.
We are now carrying the short-range Sharp GP2Y0A51SK0F Analog Distance Sensor. Like the GP2Y0D815Z0F we released a few months ago, this sensor has a maximum intended sensing range of 15 cm, but unlike that other sensor, this module tells you where the detected object is in its 2 cm to 15 cm range. Its close minimum sensing distance of 2 cm and high 60 Hz update rate make this a great choice for close-proximity range-finding, or the analog voltage output can be passed through a comparator to make an adjustable-threshold alternative to our digital Sharp distance sensors.
This sensor uses a 1.5 mm pitch JST ZH connector, which is different from the connectors on all the other Sharp sensors we carry. Unfortunately, this means it will not work with the JST PH cables we recommend for use with some of those other sensors. We are working on getting compatible cables, but in the interim, it is not too difficult (but not exactly easy) to solder wires directly to the output pins like in the picture on the right.
This sensor is also quite a bit smaller than most of the other analog Sharp sensors, so it will not work with our new brackets.
A variety of Sharp distance sensors. From left to right: GP2Y0A02, GP2Y0A21 or GP2Y0A41, GP2Y0A51, and GP2Y0D8xx.

Stackable 0.100″ Female Header: 2×20-pin, Straight.
We now have special extended, stackable female headers for the Raspberry Pi:
- Stackable 0.100″ Female Header with Extra 0.3″ Spacer: 2×20-pin, Straight
- Stackable 0.100″ Female Header: 2×20-pin, Straight
- Stackable 0.100″ Female Header with Extra 0.2″ Spacer: 2×13-pin, Straight
- Stackable 0.100″ Female Header: 2×13-pin, Straight
The 2×20 versions work with the Raspberry Pi Model B+ (and the just-released A+), while the 2×13 versions match the I/O header on the older Raspberry Pi Models A and B.
See our Raspberry Pi category for our full selection of Raspberry Pi accessories.
We are now carrying the USB version of the BASIC Stamp Discovery Kit. Please see the product page for more information.

Several gear ratios of our medium-power (MP) micro metal gearmotors are now available with extended motor shafts:
- 10:1 MP micro metal gearmotor with extended motor shaft – 2200 RPM (no-load) and 3 oz-in torque (stall) at 6 V
- 75:1 MP micro metal gearmotor with extended motor shaft – 290 RPM (no-load) and 17 oz-in torque (stall) at 6 V
- 100:1 MP micro metal gearmotor with extended motor shaft – 220 RPM (no-load) and 19 oz-in torque (stall) at 6 V
The extended motor shaft rotates at the same speed as the input to the gearbox and offers a way to add an encoder, such as our new magnetic encoder for micro metal gearmotors (pictured below), to provide motor speed or position feedback.
