Spec:
1.A single module can drive an 8 * 8 common cathode lattice
2.Module Operating voltage: 5V.
3.Module size: 5 cm long X 3.2 cm wide X 1.5 cm high
4.With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed
5.Module with input and output interfaces, supports multiple modules cascade
Note:
1.VCC and GND is not reversed, it would burn the chip!
2.When the 51 microcontroller P0 port control, must be connected to the pull-up resistor, it is recommended that the resistance of 4.7K–10K.
3.Please lattice into the hole first seat, and then inserted into the round hole Block PCB board welding. Lattice word side facing the surface order from left to right pin 123456. PCB board 1 foot square pad!
4.Electrolytic capacitors long-legged as positive, negative short legs; ceramic capacitor without the positive and negative points.
