Custom C8051F020 F120 F040 Small System Learning and Development Board Core Board

Main features of the development board:

The appearance design of the product is exquisite, from the design of the schematic to the completion of the PCB, everything is based on the principle of continuous improvement. Reasonable component layout, standardized and precise manual wiring are incomparable to the software's built-in automatic wiring, in order to further improve the performance of the product

The SMT components are produced by machine reflow soldering

The pins for pin expansion are all led out with a standard 2.54mm spacing and clearly labeled. The arrangement of each port has been optimized for more convenient use. The spacing between the two rows of pins for pin expansion is designed according to the commonly used spacing of a universal board. Therefore, if you want to insert this system board into a hole board, simply install and weld the pins facing downwards

◆ The default shipment is suitable for external circuits with DuPont wires soldered with the pins facing upwards. If you need to solder with the pins facing downwards or do not solder the pins, please indicate when purchasing.

Shipping list:

◆ One development board
