Overview

Shift register experimenter's board (this is PCB only, no parts, kits are available here)

Details

• The board is 2" x 2"
• Works with 3 different chips: TPIC6C595, 74HC595, and TLC5916
• 8 3mm LEDs, but 5mm will also fit
• 8 current limiting resistors for 595s, which can be shorted when 5916 is used
• Resistors on the header can be used to temporarily increase LED current
• LEDs have separate supply, but there's Vcc jumper
• Outputs are available on the header for use with external LEDs
• Pull-up resistors on CLR, OE, and LE (OE and LE can be grounded with jumper)
• Boards can be daisy chained
• 5916's resistor can be soldered in or on the header

Notes:

• NEVER insert more than one chip. Insert only the one you want to work with.
• DO NOT use resistor shorting jumpers (SV1) with 74HC595 or TPIC6C595, use only with TLC5916 (constant current driver.)
• LEDs can be supplied with higher voltage when TPIC6C595 or TLC5916 is used, use VLED pin (J1.)
• For single supply voltage, short VLED and Vcc pins (J1.)

Uses

experiment with LEDs, servos, matrix displays, etc.
