Power Supply
The Bambino 210 is powered from the USB device port on J4. The Bambino 210E can be powered from the USB device port (J4) or the power jack (J1). A FET is used to automatically select power from J1 should power be applied both the USB device port and J1.
J1 comes standard with a 2.1 mm inner diameter and 5.5 mm outer diameter, positive center tapped female power supply jack. The minimum voltage that can be applied to J1 is 7 VDC and the maximum is 15 VDC. J1 can be changed to a 2 position screw terminal by desoldering the power jack and soldering in a screw terminal. A diode (D2) will protect the Bambino 210E should polarity of the power supply be reversed on the J1 connector. The protection diode is limited to a maximum of 1 amperes through it.
Onboard Peripherals
USB Device
The Bambino 210 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. The Bambino 210 is powered through the USB device port.

Boot Jumper
The boot jumper is used to put the Bambino 210 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 210 comes standard with a user push button, a reset push button, and two 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 LPC4330. User LED2 (green) can be illuminated by clearing GPIO5[5].

Serial Flash Memory
The Bambino 210 uses serial flash for program and nonvolitile data storage. It uses the LPC43030's Quad SPI Flash Iinterface (SPIFI). The SPIFI interface has data rates up to 52 MB per second. The Bambino 210 comes standard with 4M of flash and the Bambino 210E comes standard with 8M of flash.

10/100 Ethernet (210E Only)
The Bambino 210E is equipped with a fully-integrated 10/100 Mbps Ethernet port. The Media Access Control (MAC) is implemented in the LPC4330 and the Physical (PHY) layer is implemented with Micrel’s KSZ8031. J3 is the RJ-45 connector and it has integrated magnetics and LEDs completes the Ethernet sub-system. Please see the KSZ8031 data sheet for further information on the PHY and the LPC4330 User's Manual for the MAC.

MICRO SD (210E Only)
The microSD socket (J2) enables micro-secure-digital memory cards to be plugged into the Bambino 210E microcontroller board. The microSD card allows the user the ability of a standard removable media for transferring data to and from the Bambino 210E. The LPC4330 interfaces to the microSD card through the Secure Digital Input Output card interface.

XBEE (210E Only)
The XBEE socket adds wireless support to the Bambino 210E. Digi International has several different versions of XBEE modules with different wireless protocols in the same physical footprint. Zigbee and WiFi are a couple of protocols supported by Digi International's XBEE modules. Please see Digi International's website for further details. The XBEE signals are shared with socket 5. Socket 5 should not be used if the XBEE module is being used.
