Core Board​

The Core board (Folotoy Core) connects to the interface expansion board via two 20Pin 2.0mm pitch headers. Enthusiasts can design their own expansion boards.

Interface Expansion Board​

The interface expansion board mainly extends various peripheral interfaces for the core board, with the following expansion interfaces:

  • Core Board Interface: 1 x 2.0 female header - 20Pin*2
  • Button Interface: 3 x PH2.0-2Pin, the LED next to the button expansion interface will light up when the button is pressed
  • Microphone Interface: 1 x PH2.0-2Pin
  • Speaker Interface: 1 x PH2.0-2Pin
  • RGB Light Strip Interface: 1 x PH2.0-3Pin
  • Battery Interface: 1 x PH2.0-2Pin
  • USB Interface: 1 x TypeC
  • Charging Indicator Light: To indicate charging status
  • Volume Adjustment Interface: 1 x XH2.54-3Pin
  • Switch Interface: 1 x XH2.54-2Pin

Buttons​

Three buttons, when the button is pressed, the signal is connected.

Microphone​

The microphone uses an electret microphone.

Speaker​

The speaker uses a 3W 4Ω speaker.

RGB Light Strip​

The WS2812B programmable light strip is used.

Volume Adjustment and Switch Knob​

The volume adjustment and switch function is integrated on a 5Pin knob. Rotate clockwise to increase the volume, counter-clockwise to decrease the volume. At the limit position, the source is turned off (when the power switch is switched, a "click" sound will be heard).

USB Interface​

Supports powering the kit, charging the battery, and upgrading the firmware via the TypeC interface.

Charging Indicator Light​

Located between the USB interface and the battery socket, it lights up during charging, turns off when fully charged, and flashes if no battery is installed.
