Seamless splicing and so that the dot matrix can be flexible spliced. Common cathode with bright dot matrix(8*8), display fresh and brilliant picture. A screen roll freely, to achieve the perfect picture display. Since the master chip is used in Max7219 to- make product have the following characteristics). The transmission efficiency of up to 10MHz. Can be individually controlled for each point. Lowest power consumption of 450uA (one module). Power-on reset automatically display full black. Serial communication, a great saving of MCU IO, also can be extended To expand the program with SPI. For each screen brightness control, by setting the Max7219 instructions.₹200.00
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.₹3.00
The supercapacitor, also known as ultracapacitor or double-layer capacitor, differs from a regular capacitor in that it has very high capacitance. A capacitor stores energy by means of a static charge as opposed to an electrochemical reaction. Applying a voltage differential on the positive and negative plates charges the capacitor. This is similar to the buildup of electrical charge when walking on a carpet. Touching an object releases the energy through the finger.₹275.00
