Module parameters:
A single module can drive an 8 * 8 common cathode lattice
2 module operating voltage: 5V
Module size: 5 cm in length X width 32 cm x 15 cm
4 with four screws hole, aperture 3mm, Our M3 Tongzhu fixed
5 modules with input and output interface, supports multiple modules cascade
Wiring instructions:
Module on the left as an input port, output port on the right
Control of a single module, simply input port to the CPU
3 more modules cascade input termination module of a CPU, 2 output termination module input and output of the two modules is terminated with the input end of the first three modules, and so on
51 MCU, for example:
VCC → 5V
GND → GND
DIN → P22
CS → P21
CLK → P20
Note:
1VCC and GND is not reversed, it would burn the chip!
2 the P0 port control 51 microcontroller must be connected to the pull-up resistor, it is recommended that the resistance of 47K--10K
Please lattice first inserted into the round hole seat, then inserted into the round hole Block PCB board weldingLattice word side facing the surface order from left to right pin 123456PCB board 1 foot square pad!
4 as cathode of the electrolytic capacitors long-legged, short legs for the negative; ceramic capacitors without the positive and negative points
