SparkFun MicroView – OLED Arduino Module

by

Sparkfun: DEV-12923

Description

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. With the on-board 64×48 pixel OLED, you can use the MicroView to display sensor data, emails, pin status, and more. It also fits nicely into a breadboard to make prototyping easy. The MicroView also has a full-featured Arduino library to make programming the module easy.

In the heart of MicroView there is ATMEL’s ATmega328P, 5V & 3.3V LDO and a 64×48 pixel OLED display, together with other passive components that allow the MicroView to operate without any external components other than a power supply. Additionally, the MicroView is 100% code compatible with Arduino Uno (ATmega328P version), meaning the code that runs on an Arduino Uno will also be able to run on the MicroView if the IO pins used in the code are externally exposed on the MicroView.

Features

* 64×48 Pixel OLED Display
* ATmega328P
* 5V Operational Voltage
* VIN Range: 3.3V – 16V
* 12 Digital I/O Pins (3 PWM)
* 6 Analog Inputs
* Breadboard Friendly DIP Package
* 32KB Flash Memory
* Arduino IDE 1.0+ Compatible

Dayton Audio: 3″ Full-Range Driver

by

Dayton Audio: Reference Series 3″ Full-Range Driver

Dayton Audio: RS75T-8 & RS75-4

RS75T-8 3″ Reference Full-Range Truncated Frame 8 Ohm

Quick Overview

Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75T-8 can outperform “boutique” drivers that cost several times the price.

Product Highlights
• Truncated cast frame-great for line arrays and MTM speaker designs
• Full-range performance
• Low distortion and high resolution
• Aluminum frame, aluminum cone, rubber surround
• Distortion-reducing copper ring, copper cap, and aluminum phase plug
• Subtle yet high-tech look makes a bold cosmetic statement

Product Description

The Dayton Audio Reference Series sets a new standard of value in high-performance loudspeaker drivers. Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75T-8 can outperform “boutique” drivers that cost several times the price. The driver’s truncated frame makes it ideal for line arrays and ultra-compact MTM designs requiring minimal driver-to-driver spacing. Its low-distortion characteristics and smooth response provide exceptional clarity, detail, and dynamics. Features a black anodized cone, heavy-duty 4-hole cast frame, low-loss rubber surround, and gold terminals.

RS75-4 3″ Reference Full-Range Driver 4 Ohm

Quick Overview

Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75-4 can outperform “boutique” drivers that cost several times the price.

Product Highlights
• Full-range performance
• Low distortion and high resolution
• Aluminum frame, aluminum cone, rubber surround
• Distortion-reducing copper ring, copper cap, and aluminum phase plug
• Subtle yet high-tech look makes a bold cosmetic statement

SparkFun: SparkFun Decade Resistance Box

by

SparkFun: KIT-13006

SparkFun Decade Resistance Box

Description

This is the SparkFun Decade Resistance Box, an involved PTH soldering kit that allows you to quickly and accurately dial in a specific resistance value between 0 and 999,990 Ohm, in 10 Ohm increments. The concept is simple, a decade box is a tool that contains resistors of many values that can be accessed via mechanical switches. All you need to do is just adjust the knobs to output any of the discrete resistances offered by the box. Once assembled, each kit will have controls that correspond to the digits in a decimal number – a control for the tens position, a control for the hundreds position, and so on.

Includes

1 x Decade Resistance Box PCB
1 x Red Binding Post
1 x Black Binding Post
5 x Rotary Switch – 1-pole 10-position, with dress washer and hex nut
9 x 10 Ohm Resistor – ¼ W, 1%
9 x 100 Ohm Resistor – ¼ W, 1%
9 x 1000 Ohm Resistor – ¼ W, 1%
9 x 100K Ohm Resistor – ¼ W, 1%
9 x 10K Ohm Resistor – ¼ W, 1%
