Five Solutions for Level Conversion Between 5.5V and 3V in UART Communication
In embedded systems, when communication is required between microcontrollers with different supply voltages, or between a microcontroller and peripheral chips operating at different voltages, level conversion is unavoidable. Otherwise, communication may fail, or the voltage may exceed the microcontroller’s tolerance, causing damage. Below are five mainstream level conversion solutions. 1. Resistor Divider Solution As shown … Read more
