=== Matrix reference ===
* sizeSize: 64x32 32x64 RGB LEDs (127x256mm)* organizationOrganization: 2 blocks (upper and lower) with each 16 lines à of 64 LEDs
* (6) 64 bit shift registers
* input pins:** R, G, B for each upper and lower: R1, G1, B1, R2, G2, B2; 1 = LED on** clock (next bit, rising edge)** latch (latch shifted data to output, rising edge)** enable (drives LEDs from latched data?, 0 = enable)** 5V signals** 40ns period = 25MHz max.
* ~4A with full matrix in white color
* price5V signals* Serial MCU Interface* Price: ~ 150.- USD    === Input pins ===# '''DR1''' - RED for lines 1-16 (1 = LED on)# '''DG1''' - GREEN for lines 1-16 (1 = LED on)# '''DB1''' - BLUE for lines 1-16 (1 = LED on)# '''GND''' - Ground Reference# '''DR2''' - RED for lines 17-32 (1 = LED on)# '''DG2''' - GREEN for lines 17-32 (1 = LED on)# '''DB2''' - BLUE for lines 17-32 (1 = LED on)# '''GND''' - Ground Reference# '''A''' - Used for the bit selection of one of 16 rows# '''B''' - Used for the bit selection of one of 16 rows# '''C''' - Used for the bit selection of one of 16 rows# '''D''' - Used for the bit selection of one of 16 rows# '''CLK''' - Clock imput for 74HC595 shift register# '''LAT''' - Content of 74HC595 Shift Register transferred to output latches# '''EN''' - Enable 74HC138 encoder to set one of 16 rows (0 = enable)# '''GND''' Ground Reference
