Simple RS232 to TTL Level Converter

This webpage describes how to build a simple RS232C level converter using transistors.

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 […]
