More mini breakout boards for 18-pin PIC16F series microcontrollers are now available as DIY kits on Tindie. 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).

This mini breakout board is designed to simplify prototyping and experimentation work with the popular 18-pin PIC16F series microcontrollers. It is small in size (1.95″ X 0.75″) and is breadboard friendly. It supports PIC16F84A, PIC16F628A, PIC16F88, PIC16F648A, PIC16F1827, PIC16F1847, and other 18-pin microcontrollers in the same series.

Revised version of the PIC12F microcontrollers breakout board

Posted on February 3, 2013 by R-B One comment

The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice cookers, vacuum cleaners, coffee makers, and blenders. Despite their small size, the PIC12F series microcontrollers offer interesting features including wide operating voltage, internal programmable oscillator, 4 channels of 10-bit ADC, on-board EEPROM memory, on-chip voltage reference, multiple communication peripherals (UART, SPI, and I2C), PWM, and more. This is a revised version of the previous
