41822B development board is a PCB that is usually used for development purposes. It usually carries one or more MCU/FPGA devices as the core, and some peripherals such as Flash, SRAM, SDRAM, LED, nixie tube, TFT LCD and other peripherals as auxiliary development, as well as some additional pins.

Drive board, usually used to drive specific peripherals, such as high-power stepping motor, large LCD screen, etc.

41822B motherboard, or backplane, usually plugs the development board or core board into it, and connects the driver board to it, which mainly serves as a large connector. When the peripherals on the development board or core board are not enough, some additional peripherals will be deployed to assist the development and finally form the whole product.

41822B development board mainly refers to the minimum system with mcu and some simple peripheral circuits. It is convenient for users to realize some basic functions.

41822B drive board, which drives different hardware devices, such as motor drive board, can be used to drive the motor.

The 41822B motherboard is actually the motherboard. You can understand it as the main circuit board. Motherboard has many interfaces, and usually carries many daughter boards with other functions. Daughterboards are circuit boards that realize many other functions. Such as a computer motherboard.

The development board can only light one lamp at most.

The driving board is used to control the output of large current and voltage. Because the output current of the development board is generally very small, it can only be lit, so it is necessary to cooperate with the driving board to control the high-current equipment such as the motor.

Motherboard is a circuit board that integrates boards such as driving board and development board.
