PROS
Excellent.
CONS
None!
Straight out of the box this device is pre programmed with some demonstration software. Very good for a quick introduction. Programming this with arduino will require some experience, you will have to define the camera pins in your (or modified example) software. Once accomplished, you can then assign you own secure IP address e.t.c. Brilliant. Enjoy!

PROS
Excellent device all round.
CONS
Product description may be incorrect. See review.
From my understanding, an ACTIVE buzzer simply connects to 5V and continuously emits a 1KhZ tone. These are PASSIVE buzzers and require a modulated (PWM) Signal to drive them. This is advantageous because frequency and amplititude are controlable. Thanks FastTech.

PROS
Versatile and well designed.
CONS
None!
Everything you need to experiment without a breadboard and lots of additional wiring. This is because the designer has conveniently placed a GND and 5V adjacent to all I/O pins. I like the 4 pin I2C and Serial Port pin headers next to extra 3.3V and GND pin headers. Excellent work Funduino and FastTech!

Excellent product.
CONS
None.
Have purchased many of these and all of them function exactly as described. Max charging current 1 Amp, charge Voltage termination at 4.2V. It's that complicated!!! Great product. Thank you FastTech.

This is superb for powering low power projects. I have tested this with LiPo and Lion cells ranging in capacity from 500 to 3000 mAh. All worked well. The mini USB is for charging from a standard USB charger source if required. It draws a maximum of 500mA @5V. Can simultaneously supply to load and charge battery when switch is on. Battery only will charge when off. For a low light level climate, charging with a 16 to 24 volt panel regulated down to 5.8 volts works great. Highly recommended.
