Keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator) of microcontroller. There 54 groups of I/O (input/output ) digital ends (of which 14 group to do PWM output),
This LED module is of high brightness because the lamp beads it carries is 3w. We can apply this module to Arduino projects. For example, intelligent robots can use this module for illumination purpose.
