pcs." 00 Dot Matrix Display Chapter.Overview and Main Feature * Dot Matrix Display Boards are manufactured by Sure Electronics. They can be driven by SPI like interface. They can be easy interfaced to any Microcontrollers. They can be widely used in panel meter, big clocks and any other information display usage. Sure Electronics provides series of such * Dot Matrix Display Boards which are supposed to reduce your development time and make them standard. In this series, there are.inch, inch and inch display boards. They can display all the ASCII characters. If any special characters and special size ones are needed, you could contact us with the contact information at the end of this document. -. Gallery Figure 00-00 Sure Electronics Inc.

Overview and Main Feature -. Main Feature * Dot Matrix display with HC shift register to store latched data. All ASCII characters are stored inside the PICF microcontroller. Some special characters besides ASCII codes are memorized in PICF for displaying, and listed in the character map. PWM signal can be supplied to control brightness of Dot Matrix information segments. Power can be supplied and data can be transmitted by IDC sockets from microcontrollers. Auxiliary power supply terminal blocks may be needed when connected to next LED matrix board. For over matrix boards serialized, those aux power input terminals must be used, if not, the final ones in the chain will be dimming. DE-DP0-Ver.0-page 00-00 Sure Electronics Inc.

Hardware Detail Note:. Because of the LED's voltage drop difference, the resistance may vary from the value marked in the schematic. For White, Blue, Green and Pink, UV LEDs, the voltage drop is around.volts, and for Red, Yellow, Orange, the voltage drop is.0 Volts or so.. The above schematics are just for reference.
