Welcome to my stores, The Smart of your choice and satisfaction guarantee. 6 PCS 8-Digit 7 Segment MAX7219 Digital Segment Module Seven Section 8 Bit LE... Gallery Product Description Descriptions: MAX7219 is an integrated serial input / output common-cathode display drivers, which drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Includes an on-chip a BCD code-B decoder, multi-channel scanning loop, segment and digit drivers, but also a 8x8 static RAM that stores each data. Only one external register is used to set the current of each LED segment. The MAX7221 is compatible with SPI, QSPI, and MICROWIRE, and has slew-rate-limited segment drivers to reduce EMI. The MAX7219 chipset supports a serial 16-bit register/data buffer which is clocked in on pin DIN every time the clock edge falls, and clocked out on DOUT 16.5 clock cycles later. The entire device includes a 150µA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode. Wiring instructions (take the provided program as an example, you can pick any IO port definition can be modified in the program): VCC -> 5V GND -> GND DIN -> P00 CS -> P01 CLK -> P02 Note: 1.VCC and GND do not reversed, it would burn the chip 2.51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines Package Included: 4 * MAX7219 8 bit digital display module Features ☂MAX7219 is an integrated serial input / output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits; MAX7219 digital display control module, you can use it for ☂The module is compatible of 5V / 3.3V microcontroller; Only three IO ports are used to drive the eight digit display. ☂Only three IO ports are used to drive the eight digit display. MAX7219 supports flicker free displays as well as cascading displays; PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen. ☂Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01; Digital tube is 0.36 inch 4-bit integrated cathode digital tube; Common cathode. ☂Note:VCC and GND do not reversed, it would burn the chip.51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines.
