Video: LVBots April 2015 line following competition
- 22 January 2019The end of the blog post contains links to several different builds for robots in the competition. I suggest looking through them to see what kind of components were used in their robots.
Robot Zero: a fast line follower for beginners
- 18 January 2019Thank you for pointing that out. We fixed the link to point to an archive of that article, so you should be able to access it now.
Ibex: a wall-climbing robot by Operative RC
- 1 October 2018We did not make the Ibex robot, and unfortunately, it looks like the Operative RC website is no longer running; you might try posting your question in the thread on our forum for the robot, to see if Lukeness might answer.

New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 24 August 2018The driver includes three on-board 150 µF capacitors, which might be sufficient for brief tests and limited low-power operation, but adding a bigger capacitor of a few hundred μF and rated well above the maximum supply voltage is strongly recommended for most applications.

Powerful new U3V50x boost regulators
- 6 April 2018Hi, Phil.
We detail the connections for those regulators (including the ENABLE pin) on their respective product pages. The ENABLE pin can be driven low (under 0.7 V) to put the board into a low-power state. If you do not need this feature, you should leave the ENABLE pin disconnected.

New product: Addressable high-density RGB LED strip
- 26 March 2018Hello, jhon.
We do not carry the WS2812B LED strips any longer. We do offer the SK9822/APA102C and SK6812 in 1m lengths and 30 or 60 LEDs per meter densities.
All of our LED strips can be purchased through our website.

Raspberry Zumo Robot
- 5 January 2018Hello, Murat.
We did not make that robot, but the blog post says they used a stripped-down Logitech webcam. Unfortunately, it looks like that website link for the "Raspberry Zumo" is having problems. You might try again at a later time to see if that content comes back up. In the meantime you can see the archive of that website post here:

MSOE underwater robotics ROV
- 14 December 2017Hello,
We are not sure of the exact connectors they used on that system. I suggest asking the MSOE Underwater Robotics team through the link above.

New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 12 September 2017Yes, the + and - locations are the intended location for adding a capacitor to the motor power supply. You can also add additional capacitance across VIN and GND if you need it.

New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 11 September 2017Hello, kodenma.
The motor supply pin is labeled VIN, so you should put the capacitor across VIN and GND.
