Bambino-210 Manual/User Interfaces, Connectors, and Jumpers
From Manuals
The following image shows where the connectors, headers, and jumpers are located on the Bambino 210.
Power Supply
The Bambino 210 can be powered from the USB0 device port on J4 or MBED HDK/USB1 device port on J6. The Bambino 210E can be powered from the USB0 device port, MBED HDK/USB1 device port, or the power jack (J1). A power mux automatically selects the power between USB0 and the MBED HDK/USB1. A FET is used to automatically select power from J1 should power be applied both the USB device ports 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.

Coin Battery
The Bambino 210's microcontroller has a built in real-time clock calendar that can be battery backed by supplying 2.2 VDC to 3.6 VDC to the VBAT pin on the LPC4330. A battery holder can be added to the bottom of the board to power the VBAT pin with a coin cell battery. The battery holder is manufactured by Keystone and it's part number is 3002. The battery holder accepts CR2032 series coin cells. Power is only drawn from the battery when the power is off to the Bambino 210.
Cortex M JTAG
A JTAG port (J5) can be added for software download and debugging. The JTAG port allows users to set break points and to single step through their program.
