A-One Counterparts

The OSEPP Fio board has wireless in mind. This board may connect to an XBee radio (sold separately) and has a connector for a lithium polymer battery which can be charged over the USB connection.

Specifications:
Microcontroller: ATmega328P
Clock Speed: 16 MHz
Flash Memory: 32 KB
SRAM: 2 KB
EEPROM: 1 KB
Operating Voltage: 3.3V
Input Voltage: 3.35-12 V
Digital I/O Pin Count: 14 (including 6 for PWM output)
Analog Input Pin Count: 8
Other Connections: Mini-USB (charging), ICSP for ATmega328P (req. header), XBee module socket, Lithium Polymer battery connector
Dimensions: 2.56 x 1.10 x 0.47 inches (65.0 x 28.0 x 12.0 mm)
Power Source: USB or external Lithium Polymer battery

Highlights:
• 8-bit AVR RISC-based microcontroller running at 8 MHz
• On/off slide switch
• Charging circuit for lithium polymer battery
• Connector for interfacing with XBee modules
• Flexible power source (USB or lithium polymer battery)
• Compatible with existing Arduino software libraries

Features:
The ATmega328P comes with the Arduino bootloader preloaded. Should you wish to update or replace the bootloader, there are ICSP (In-Circuit Serial Programming) pin-outs that can be used in combination with a header (sold separately) for the ATmega328P.
The bottom of the board comes with pre-mounted headers for connecting to an XBee module for wireless applications.
To allow portability, the board can be powered by a lithium polymer battery. The board includes circuitry to allow the battery to be charged via a powered mini-USB connection. A resettable polyfuse on the USB path will trip when the current exceeds 500 mA, preventing board damage.
