Nano undershield revision 2
Almost a year ago I designed my first PCB. It was a small 50x50mm PCB that acts as an undershield for an Arduino Nano. I designed it because the Arduino Nano has a tiny 5V voltage regulator. To not overheat the regulator you can not draw more then 200-300mA from it depending on the input […]
Volga: the line following robot
A couple of months ago I started building a line following robot, I named it Volga 🙂 The plan was to draw a small track and plot it out on a large piece of paper and make a robot that could follow the track. In this case the plan was successful as tonight my little […]
My Arduino Nano undershield
My Arduino Nano undershields arrived this week from Iteadstudio in Shenzen, China. I received 12 PCB’s, but I only have one Nano, anyone want an undershield for your Nano? My undershield has a 3A 5V LM2576 switchmode regulator to power the Nano. All the pins from the Nano are brought out to male headers with […]
