Key features: On board Reset switch and decoupling capacitor High quality PCB (manufactured from OSH Park) Easily plug into a breadboard On board ceramic resonator (20MHz) ICSP header for PICKit2/3 connection All 18 pins of the microcontroller are broken out to a breadboard friendly 0.1″ pitch header You can buy this as a DIY kit for $8.50 on Tindie.

I2C EEPROM plus Temperature Sensor breakout board

Posted on February 26, 2013 by R-B 3 comments

This tiny breakout board carries Microchip’s 24LC512 EEPROM and MCP9802 temperature sensor devices, both of which support I2C protocol. This board can be used for both sensing the ambient temperature and storing it. The MCP9802 is a digital temperature sensor with an user-selectable resolution from 9 to 12 bit. It can measure temperature ranging from -55°C to +125°C and notifies the host microcontroller when the ambient temperature exceeds a user programmed set point through its ALERT output pin. This board allows you to store up to 32000 temperature samples when you use the sensor in high resolution mode (12-bit, 0.0625°C)

New version of MAX7219 based 4-digit serial seven segment LED display

Posted on February 20, 2013 by R-B Leave a comment

This (SPI7SEGDISP4.40-1R) is a revised version of the previous SPI seven segment LED display (4 digit) board that displayed numerals and decimal points. The new version has a better quality seven segment LED display (LTC-4727JS) with three extra LED segments, as shown below. The additional colon segments are useful in projects where you need to display time (HH:MM or MM:SS).

Netduino Day 5 – Writing to an SD Card

Posted on February 14, 2013 by ANir 3 comments

Expandable memory is always a plus no matter whether it’s a Phone, Camera or a Microcontroller. Even advantageous if we know how to use it. In this fifth day Netduino tutorial, we will learn a few writing operations about an SD card. We will learn how to write to a text file, shown as an example of writing a log. The Logger class is also capable of creating a text file at any given location then writing some text information to it.
