Pololu Robotics and Electronics Black Friday / Cyber Monday Sale 2016

Our Black Friday / Cyber Monday sale is going strong, and we have been working hard to make and ship the products that people are getting great deals on. If you have already placed an order, thank you! If you are still trying to decide if you want to take advantage of our amazing deals, don’t wait too long—the sale ends Monday night.

Act now to get free-ish shipping during our Black Friday/Cyber Monday Sale!

Posted by Ben on 21 November 2016



We’re less than two days away from our annual Black Friday/Cyber Monday sale, our biggest sale of the year! This year, in addition to our usual doorbuster deals (limited total quantity promotions at extreme discounts) and large discounts, we are offering up to $7 off of shipping for those who claim their coupon before the sale begins. For many of our smaller items shipping within the US, that discount will be enough to make shipping free, and it should also make a meaningful reduction in shipping costs for our international customers who want to participate in this American tradition. To take advantage of this offer, just log in to your account and follow this link, which will generate a coupon code just for you. You must get your coupon before the sale begins, and you can then use it during our sale, which will run from Wednesday, November 23 through Monday, November 28. Keep an eye on our Black Friday/Cyber Monday sale page for all the latest about the sale!

New product: Raspberry Pi Model A+ 512MB RAM

We are now carrying the Raspberry Pi Model A+ 512MB, which is just like the previous Model A+ but with double the RAM, so it also works with our various Raspberry Pi expansion boards. In particular, it can be combined with our A-Star 32U4 Robot Controller with Raspberry Pi Bridge to make a powerful control center for a small robot (check out this tutorial).

And speaking of small robots, stay tuned for some fun new products that will also work with the Raspberry Pi!

New versions of our 38 kHz IR proximity sensors

Posted by Ben on 17 October 2016
Tags: new products

We have released slightly updated (irs05b) versions of our 38 kHz IR proximity sensors and discontinued the previous (irs05a) versions. The main changes are to the locations of the IR emitter and receiver, which have been moved away from the edge of the board. This results in better shielding from the PCB itself, which improves performance. Also, the front edge is now routed rather than scored to provide a cleaner edge that also slightly improves the sensor performance and consistency.

Like the originals, these new sensors are available in high-brightness and low-brightness versions with typical sensing ranges up to around 24″ (60 cm) and 12″ (30 cm), respectively. The new versions have the same dimensions and pinouts as the originals, so they can be used as drop-in replacements for any applications that are not dependent on the original component locations.

Tags: new products

We just added 16 new micro metal gearmotors to our already huge selection, including three totally new MP (medium power) gear ratios: 5:1 MP, 210:1 MP, and 250:1 MP. With these new additions, we now have dual-shaft versions available in any combination of our 11 gear ratios and four motor types, giving you 44 different options that work with encoders like our magnetic encoder pair kit.

New products: MinIMU-9 and AltIMU-10 v5 IMU boards

Posted by Ben on 4 February 2016
Tags: new products

We have released new versions of our MinIMU-9 and AltIMU-10 inertial measurement unit (IMU) modules, which use an I²C interface to provide nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation (the AltIMU also includes an altimeter). These v5 editions feature ST’s new LIS3MDL 3-axis magnetometer and LSM6DS33 3-axis accelerometer and gyro, which allow them to offer improved performance over previous versions at lower prices. The new versions are pin-compatible with the previous ones, though software written for older IMU versions will need to be changed to work with the v5 since the sensor ICs have changed.

We think these new boards combine the best ST MEMS sensors into compact boards at great prices. However, our older MinIMU-9 v3, AltIMU-10 v3, and AltIMU-10 v4 are still available for now at reduced clearance prices, so if you don’t absolutely need ST’s newest sensors on your IMU, these previous versions are still very good sensor boards to consider.

Here’s an updated version of our diagram showing where the new v5 modules fit in:
