NB2A Physical Computing Tools

The NB2A is a physical computing development system that is compatible with the Arduino/Sanguino tools. The form-factor matches the "standard" Altoids tin.
The picture on the right shows an NB2A + NB2-LI-ION connected to a NB2A-PB1 with an IDE ribbon cable. Additional boards can be connected with the same cable. In this configuration both boards were built with vertical headers. The other configurations are --

• Backplane all boards are built with right angle connectors.
• Co-planar all boards are built with right angle connectors. The header is used for output and the receptacle is used for input.
• Parallel Vertical mating connectors.

NB2A Microcontroller Board

Features

• Replaceable and upgradeable CPU
• Compatible with the Arduino development tools (with Sanguino add-ons).
• ATmega644P running at 12MHz with a Vcc of 3.3V.
• 3.55" x 2.15". Fits in the "standard" Altoids tin.
• Atmega I/O, DAC and RTC connections are wired to a single header. Application boards can be mounted parallel using vertical connectors, co-planar using right-angle connectors or remotely using a cable.
• DAC Features
  • Two channels, 12 bits per channel.
  • Reference -- 1.225V, ±0.1% (initial accuracy), 100ppm/°C max drift,
  • SPI Interface
• RTC Features
  • Real-Time Clock (RTC) counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap-Year Compensation Valid Up to 2100
  • Two Time-of-Day Alarms
  • Programmable Square-Wave Output
  • Powered by a CR1220 coin cell.
  • I2C Serial Interface
• 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.
• 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.
• Accessories include a prototyping board NB2A-PB1, a terminal board NB2A-TB1 and a Li-Ion battery charger (Q1-2010).

NB2A-PB1 Prototyping Board

• Input connector is compatible with the NB2A output connector.
• 3.55" x 2.15" breadboard area with TH and SMD patterns. Pattern features a DIP, SOIC and SOT23-6 pattern overlay.
• Two bounceless push-buttons (with optional SMD components). The pushbuttons can be jumpered to digital input pins if the SMD components are not used.
• Two debug LEDs.

NB2A-TB1 Terminal Board

• Input connector is compatible with the NB2A output connector.
• 3.55" x 2.15" PCB with two 20-position terminal blocks.
• LED indicator for the 3.3V power supply.
