desktop console

ESP32 is used to control the 0.96-inch OLED. There is a TYPEC on the back that can be used as an input or output control port. The TYPEC port has two inputs and outputs that can be used to control the WS2812 light strip, or the ADC input can be used as a simple oscilloscope.
The expansion dock uses SL2. 1A chip, the front two interfaces can be connected to U disks, etc., and the back two interfaces can be connected to keyboards and mice to reduce desktop wiring. The first is
the mode selection switch.
The second to sixth are five USB output control switches.
The next to fourth are expansion. The fifth below the docking switch
is the ESP32 switch, and
the sixth below is the backlight switch. There is a built-in blue backlight.
The two buttons on the left are the main power switch (this PCB uses two 5V inputs. If the current is small, the two input ports can also be connected. Use together)
The OLED screen can add functions according to needs.
The ESP8266 interface is also reserved on the ESP32. If you do not need the TYPEC port behind, you can change 32 to 8266 and brush the code of the weather clock
(at this time, CH340N and onboard TYPEC can No welding)
