Interfacing the 3-V MSP430 to 5-V Circuits

On Dangerous Prototypes, they point to an app-note from TI which shows various ways of level-shifting between a 3V MCU (like the MSP430) and 5V peripherals. The paper includes various examples for input, output and bi-directional level-shifting. They also cover the topic power-supply, giving examples on how to provide both: 3V and 5V to your […]

Robot with MSP430 Launchpad as Brains

Longhorn engineer has has a nice and clean robot build with an MSP430 Lauchpad as Brains on his web-page. I like especially the design of the power supply: It has 3 switching power supplies providing 3V at 4A, 3.3V at 500mA, and 5V at 1A. The main power source is a single cell 3.7V lithium […]

Some more Video Tutorials

On “JumperOne” I found some more video tutorials covering various things regarding electronics. E. g. there you can find a tutorial on how to build a bench power supply out of an ATX power supply.
