We are offering 30% OFF (coupon code BDEA254) on SPI7SEGDISP8.56-2R this weekend (May 31 – Jun 2, 2012). SPI7SEGDISP8.56-2R is a MAX7219-based seven segment LED display board with 8-digits which are arranged in two rows of four. The MAX7219 allows you full control of all the digits and decimal points through three I/O pins of a microcontroller. The communication interface is SPI-compatible, and the brightness of the LED segments can be controlled through software.
SPI7SEGDISP8.56-2R: MAX719-based seven segment LED display module
Key Features:
- 3-wire SPI interface
- double row of 4-digit displays (0.56″)
- operates at +5V supply
- individual control of all digits and decimal points
- 16 levels of display brightness through software
- PCB dimensions 2.8″ x 1.7″ (70mm x 42mm)
- Two or more of these modules can be cascaded in series
Since it requires only 3 I/O pins, this display module can also be used with low pin-count microcontrollers (such as PIC12F series). Visit my MAX7219 tutorial page for more detail on MAX7219 and PIC12F683 interfacing example. With Arduino, it can be easily interfaced using the LedControl library.
It is available in three LED colors: Red, Blue, and Yellow. The buying links are provided at the end.
