NB1 Physical Computing Tools
The NB1 is a physical computing development system that is compatible
with the Arduino software environment. For system development a
variety of peripheral modules are available. The datasheet is located
here
NB1 Microcontroller Board
Features
- Replaceable and upgradeable CPU
- Compatible with the Arduino development tools.
- 2.95" x 1.75"
- ATmega168 running at 12MHz with a Vcc of 3.3V.
- I/O connections are wired to a single 26 pin header. Application boards can
be mounted parallel using vertical connectors, co-planar using
right-angle connectors or remotely using a flexible cable.
- Side header connector (J4) is wired to two digital lines and the
receive and transmit lines from the UART. A UART enabled device (such
as an XBee or a Bluetooth radio) board can be connected to the right side of the NB1.
- The board can be built with either a USB interface
or with a six pin header for use with an USB to serial cable.
The USB interface circuitry includes transient
suppression and current limiting resistors.
- ICSP port (3.3V levels)
- A/D reference supply filtered per Atmel specification.
- Reset circuit per Atmel specification.
- Power supply is jumpered between either an LDO or an external
3.3V supply. The LDO input is diode or'ed from a wall adapter or the
USB 5V supply.
- Compatible with all the ZB1 peripherals.
NB1A Microcontroller Board
Features
- Replaceable and upgradeable CPU
- Compatible with the Arduino development tools.
- ATmega328 running at 12MHz with a Vcc of 3.3V.
- 4.4" x 1.75"
- Atmega I/O connections are wired to a single 26 pin header. DAC
and RTC interrupt output lines are wired to an 8 pin
header. Application boards can be mounted parallel using vertical
connectors, co-planar using right-angle connectors or remotely
using a cable.
