Englandsaurus 
Hardware Overview
Let's look over a few characteristics of the Qwiic Grid-EYE so we know a bit more about how it behaves.
| Characteristic | Range |
|---|---|
| Operating Voltage(Startup) | 1.6V - 3.6V |
| Operating Voltage(Timekeeping) | 1.5V - 3.6V |
| Operating Temperature | -40°C - 85°C |
| Time Accuracy | ±2.0 ppm |
| Temperature Accuracy | ±2.5°C |
| Current Consumption | 4.5 mA |
| I2C Address | 0x69 (open jumper, default) or 0x68 (closed jumper) |
Pins
The characteristics of the available pins on the Grid-EYE are outlined in the table below.
| Pin Label | Pin Function | Input/Output | Notes |
|---|---|---|---|
| 3.3V | Power Supply | Input | Should be between 1.95 - 3.6V |
| SDA | I2C Data Signal | Bi-directional | Bi-directional data line. Voltage should not exceed power supply (e.g. 3.3V). |
| SCL | I2C Clock Signal | Input | Master-controlled clock signal. Voltage should not exceed power supply (e.g. 3.3V). |
| INT | Interrupt | Output | Interrupt pin, digital output. |
| GND | Ground | Input | 0V/common voltage. |
Optional Features
Pull-Up Resistors
The Qwiic GRID-Eye has onboard I2C pull-up resistors; if multiple sensors are connected to the bus with the pull-up resistors enabled, the parallel equivalent resistance will create too strong of a pull-up for the bus to operate correctly. As a general rule of thumb, disable all but one pair of pull-up resistors if multiple devices are connected to the bus. If you need to disconnect the pull up resistors they can be removed by removing the solder on the corresponding jumpers highlighted below.
I2C Address
There is an additional jumper on the back of the board that allows the I2C to be changed from the default 0x69 to 0x68 if you have multiple GRID-Eye cameras on the same I2C bus. Normally open, the jumper sets the I2C address to 0x69. Closing the jumper with solder will give an I2C address of 0x68. However, if you have more than 2 GRID-Eye's, you'll need the Qwiic Mux to have them all on the same I2C bus. The jumper is highlighted below.
