Features include:

• Atmega128RFA1 8-bit AVR low-power microcontroller
• Integrated 2.4GHz radio transceiver
• Precision temperature & humidity sensor
• Barometer/altimeter
• Light sensor (visible, IR and UV spectrum, luxmeter and UV radiation index)
• High capacity CR2450 battery holder
• Fully-compatible with Arduino, with dedicated libraries for easy programming of the sensors and radio.

This Sparrow board variant does not include any sensor, but it is size and pin-compatible with the Arduino Micro format. Also, it can run out of a single 1.5V AA battery or a single 1.2V AA NiCD or NiMH rechargeable battery. The board has a charging circuit that can deliver a steady charging voltage from a renewable power source, such as a solar panel.
