Full color RGB dot matrix drive board is a Arduino control board module specifically designed for RGB full color lattice. In addition to driving RGB lattice independently, this module can also act as an Arduino control board, which is very convenient and practical. The onboard chip is Atmega 328 chip and the ISP interface on the board has also been extracted for programming bootloader on 328 chip at any time. But, unlike other Arduino boards, this one just extracts some IIC interfaces and power supply interfaces rather than corresponding I / O interfaces.Product featuresSupport 6 colors;Support hardware 16MHZ PWMThere's no any external circuit.Private GPIO and ADC interfaceSupports hardware URAT and IIC communication mode24 road constant current channel with each channel¡¯s current reaching up to 100mA8 road source-driven constant current channel with each channel¡¯s current reaching up to 500mAWorking power supply: +5V to +5.3V.Working current: up to 300mA.Working temperature range: -10¡æ¡«£«50¡æHardware featuresSupports multiple cascades, no hardware setup needed.Supports RGB three monochrome display and mixed color display.The lattice sequence adopts rectangular plane coordinate system for easy understandingSupport Arduino development board power supply or independent external power supply.When use multiple cascades, if the color is too dim, you can increase the power supply voltage to about 5.2v. Please note that power supply voltage can¡¯t exceed 5.4VFor multiple cascades, all data lines are connected to No. 1 daughter board. (Daughter board is where the original point (0,0) resides)
