51 microcontroller minimum system (with expansion)

Overview

The difference between this 51 minimum system board and the common system boards on the market is that it has Bluetooth and 2.4G wireless module expansion. When using the 51 microcontroller to make smart cars or other projects that require wireless communication, the Dupont line can be eliminated, making the whole thing tidier. In order to meet the needs of 5V and The module uses 3v3 voltage. This solution uses AMS1117-5.0 and XC6206P332MR to reduce the input voltage to 5v and 3v3. This system board is for practicing the welding ability of novices. Most components use direct plug-in.
