Rapid Development Board for PIC12F Series Microcontrollers

Posted on November 5, 2013 by R-B 2 comments

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 many advanced 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. Today we are introducing a new development

MAX7219-based double row 4-digit seven segment LED display

Posted on April 13, 2013 by R-B 6 comments

This display board (SPI7SEGDISP8.56-2R) features eight 7-segment displays arranged in two rows of four digits. The on-board MAX7219 driver enables you to control all LED segments through only 3 I/O pins of microcontroller. The major advantage of using this board is the time-division multiplexing operations required for continuous refreshing of the display digits are performed by the MAX7219 chip, thereby keeping the microcontroller free for doing other pressing tasks. The double row arrangement is suitable for many projects where two variable values are to be displayed simultaneously, such as displaying temperature and humidity, or current and voltage, etc.

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)
