OVERVIEW

INTRODUCTION

The regulated power supply accepts unregulated inputs from 9V to 15V AC or DC and gives regulated output of 3.3V, 5V and 12V suitable for projects which needs precise voltage to work. The input can come from step down transformer. Since board has Diode Bridge input polarity does not matter. All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

FEATURES

Input Voltage AC/DC 0-12.
Output Voltages +3.3V +5V, +12V.
Inputs and output connected to terminal blocks.
Maximum Load 1 Amps.
LED Indicator.
All outputs to Screw Terminal.
APPLICATIONS

· Mobile Phone power adaptors

· Regulated power supplies in appliances

· Various amplifiers and oscillators

8CHANNEL BIDIRECTIONAL LOGIC LEVEL CONVERTER

OVERVIEW

INTRODUCTION

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.This 8-bit non inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.

FEATURES

1.2 V to 3.6 V on A Port and 1.65 to 5.5 V on B Port (VCCA ≤ VCCB).
VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State.
OE Input Circuit Referenced to VCCA.
Low Power Consumption, 4-mA Max ICC.
Ioff Supports Partial-Power-Down Mode Operation.
