- MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED.
- On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data single module can drive a common cathode 8
- 8 dot matrix
- Operating voltage : 5V Module size : 5 cm X 3.2 cm wide X 1.5 cm high holes with four screws , diameter 3mm, can be fixed by using our M3 studs modules with input and output interfaces , support for cascading multiple modules
Max7219 is a serial input or an integrated output common cathode display drivers, 7 segment digital led which connects the microprocessor with 8 bit digital display, can also be connected bar graph display or 64 independent led. It include: S an on-chip b bcd encoder, a scanning circuit, some words to drive, but also the static ram a 8 x 8 to store each data. Only an external register is used to segment the current settings for each led. A simple four wire serial interface can be connected with all general microprocessor. Each data can address does not need to rewrite all display update. Max7219 also allows the user to select each data coding or non coding. Low power consumption shutdown mode the device contains: A 150 and #x3bc; a, analog and digital brightness control, a limited scan register allows the user to display 1-8 data, there is a let all led luminescence detection mode. Only 3 io port can drive 1 dot matrix! dot matrix display without blinking
