OPT3002 breakout :: FEATURES


OPT3002 sensor breakout - topOPT3002 sensor breakout - bottom


PN: SS-OPT3002#I2C   SKU: ITBP-6008

OPT3002 (manufactured by Texas Instruments) it is an light-to-digital sensor that provide the functionality of an optical power meter within a singledevice. This optical sensor greatly improves system performance over photodiodes and photoresistors. The measurement results are compensated for dark-current effects, as well as other temperature variations.

Texas Instruments OPT3002 sensor main features:
- wide spectral bandwidth 300 nm to 1000 nm.
- maesurement levels 1.2 nW/cm2 up to 10 mW/cm2
- built-in full-scale setting feature (auto scale)
- 23-bit effective dynamic range w. automatic gain ranging
- 12 binary-weighted, full-scale range settings: < 0.2% (typ) matching bw. ranges
- ambient range for operation -40 ~ +85C
- OPT3002 sensor datasheet

OPT3002 breakout features:
* input voltages between 3.3-5V
* I2C interface, 3.3-5V auto [default I2C voltage follows the Vin powering voltage]
* I2C voltage option via solder jumper [Eg.: power at 5V and I2C at 3.3V; power and I2C at 2.2V]
* alternative sensor I2C addresses via solder jumpers
* compatible with Arduino (all), Raspberry PI (all) and other SBC / MCU
* Arduino C, Raspberry PI [Python] software support
* compatible with xyz-mIoT boards(Arduino Zero like)
* big soldering pads on 2.54 mm [0.1"] pitch for standard row header / connector

* 13x27mm, around 2grams

OPT3002 breakout :: solder jumpers description; power scenarios


s1* - I2C reference voltage selector - shipped with circuit 1-2 closed and circuit 2-3 open (default mode).

In default mode, the I2C reference voltage follows the voltage applied to Vin! Default mode use cases:
      - shield/MCU it's 5V compatible ==> connect Vin at 5V; the I2C reference it's 5V!
      - SBC/shield/MCU it's 3.3V compatible ==>connect Vin at 3.3V; the I2C reference it's 3.3V!.

Alternate mode - I2C reference voltage follows the Vdd voltage! - modify s1 as: 1-2 circuit open, 2-3 circuit closed [carefully interrupt/cut the circuit line between pads 1 and 2, and solder over pads 2 and 3].

Alternate mode scenarios:
      - apply 3.6-7V to Vin. The I2C reference voltage it's set at 3.3V! Also, at Vdd pad (LDO output) 3.3V (up to 100mA) it's available for third part powering (anyway, try to keep the sunk current as low as possible, in order to avoid thermal errors).
      - keep Vin not connected. Apply 2.8 or 3.3V to Vdd (the LDO it's bypassed). The I2C reference voltage it's set at voltage applied to Vdd pad!
