ZB2 Microcontroller Board

The ZB2 is an updated version of the ZB1. The updates include

Addition of a RTC clock.
Addition of an optional 5V supply.
Simplified layout -- all SMD components (except the optional 5V supply are on the top layer.

physical computing development system that is compatible with the Arduino software environment. For system development a variety of peripheral modules are available. See the ZB2 datasheet for the assembly instructions, schematic and bill-of-materials.

Features

Compatible with the Arduino development tools and libraries.
Thru-hole ATmega328. Replaceable and upgradeable.
XBee interface socket.
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
- Backup power from a CR1220 coin cell.
- I2C Serial Interface
3.3V Linear Regulator (800mA). Powered from a wall-adapter (SMD and TH Kits) or the USB interface (SMD kit only).
5V ± 200mV @ 100mA boost converter (SMD Kit)
Board can be built with an FTDI interface (SMD Kit) or with a six pin header for an FTDI TTL-232R-3V3 cable (TH Kit).
All I/O pins on one I/O connector strip. I/O is compatible with the ZB1/NB1x boards are peripherals.
A/D reference supply filtered per Atmel specification.
Reset circuit per Atmel specification.
Debug LED that can be jumpered to Pin 7 or 3.3V.
4.4" x 2"
