The chip can be set to ±250, ±500, or ±2000 degree-per-second scale for a large range of sensitivity. There's also built-in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily.\u003c\/p\u003e\n\u003cp\u003eSince this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level-shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V.\u003c\/p\u003e\n\u003cp\u003eSince we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws.\u003c\/p\u003e\n\u003cp\u003eGetting started is easy - simply connect SDA to your Arduino I2C data pin (On the UNO this is A4), SCL to I2C clock (Uno: A5), GND to ground, and Vin to 3 or 5VDC.

So for the 2A draw, the output will be 2V. You can change out the load resistor to be larger or smaller by cutting the traces next to it and soldering a thru-hole resistor over.

It uses a UV photodiode, which can detect the 240-370nm range of light (which covers UVB and most of the UVA spectrum). The signal level from the photodiode is very small, in the nano-ampere level, so we tossed on an opamp to amplify the signal to a more manageable volt level.\u003cbr\u003e\u003cbr\u003eThis sensor is much simpler than our Si1145 breakout, it only does one thing and gives an analogue voltage output instead of requiring a complicated I2C setup procedure. This makes it better for simple projects. It also has a 'true' UV sensor instead of a calibrated light sensor. To use, power the sensor and op-amp by connecting V+ to 2.7-5.5VDC and GND to power the ground. Then read the analogue signal from the OUT pin. The output voltage is Vo = 4.3 * Diode-Current-in-uA. So if the photocurrent is 1uA (9 mW\/cm^2), the output voltage is 4.3V. You can also convert the voltage to UV Index by dividing the output voltage by 0.1V.
