Onboard Peripherals
USB0 Device
The Bambino 100 comes equipped with a USB Device Port. The Device port is compliant with the USB V2.0 high-speed device specification. It's connector is a micro USB Type AB.
| USB0 Device Port | |
| Connector Pin# | MCU Pin Name |
| 1 | USB0_VBUS (+5.0V) |
| 2 | USB0_DM |
| 3 | USB0_DP |
| 4 | USB0_ID |
| 5 | Ground |
Boot Jumper
The boot jumper is used to put the Bambino 100 into Device Firmware Upgrade (DFU) mode. This is accomplished by shorting the two pins before power is applied or by shorting the pins and pressing the reset button. For further information please see the Getting Started Section of this manual.
User Buttons and LEDs
The Bambino 100 comes standard with a user push button, a reset push button, and four user LEDs. The user push button is connected to GPIO0[7] with a 22k-ohm pull-up resistor connected to it. User LED1 (yellow) can be illuminated by clearing GPIO3[7] of the LPC4337. User LED2 (green) can be illuminated by clearing GPIO5[5]. User LED3 (blue) can be illuminated by clearing GPIO3[0]. User LED4 (red) can be illuminated by clearing GPIO3[1].

MICRO SD
The microSD socket (J2) enables micro-secure-digital memory cards to be plugged into the Bambino 100 microcontroller board. The microSD card allows the user the ability of a standard removable media for transferring data to and from the Bambino 100. The LPC4337 interfaces to the microSD card through the Secure Digital Input Output card interface.
