When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...

The project illustrates several ways in which a 3.3V device, such as sensor, can be safely interfaced to a 5V microcontroller. Connecting a 3.3V device like the SCP1000-D01 pressure sensor with SPI ...

We’re suckers for miniaturization projects. Stuff anything into a small enough package and you’ve probably got our attention. Make that something both tiny and useful, like this 5-volt to 3.3-volt ...

This IP is a Low-Dropout (LDO) 5V to 3.3V&1.5V power regulator in GSMC 0.13um low power 4P5M e-flash dual gate process. The max output currents are 60mA (for 3.3V output) and 40mA (for 1.5V output), ...

The ESP8266 is the reigning WiFi wonderchip, quickly securing its reputation as the go-to platform for an entire ecosystem of wireless devices. There’s nothing that beats the ESP8266 on a capability ...

Do PCI 2.1/2.2 slots support both 5v and 3.3v signaling?<BR><BR>I was under the assumption that all conventional PCI devices were 5v only, but am now extremely confused at which specs support which ...

5V to 3.3V/1.8V with 80mA/40mA driving capability, Linear Regulator; UMC 0.162um GII process.
