I’ve designed another PCB 🙂 This time it’s a simple undershield for the Arduino pro mini. I received the PCB’s from Electrodragon (12$ for 10PCB’s) last week. The PCB has a Schottky diode and a 5V linear regulator, I’m using an LM2940 5V regulator. For the rest there are just 2 rows of female headers […]
I’ve bought me a pair of Pololu Wixels during the black Friday sale last month. The Wixel is based on the CC2511F32 micro controller from Texas Instruments. It has an integrated USB controller and 2.4GHz RF transceiver. The micro controller is based on Intels old 8051 architecture. I did not buy it to try and […]
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 […]
