Hardware Overview

Let's look over a few characteristics of the ADS1015 so we know a bit more about how our glove controller behaves.

CharacteristicRange
Operating Voltage2.0V - 5.5V
Operating Temperature-40°C - 125°C
Resolution12 bit
Sample Rate128 Hz - 3.3 kHz
Current Consumption150 µA (Typ.)
I2C Address0x48 (default), 0x49, 0x4A, 0x4B

Pins

The characteristics of the available pins on the magnetometer are outlined in the table below.

Pin LabelPin FunctionInput/OutputNotes
3.3VPower SupplyInputShould be between 2.2V - 3.6V
GNDGroundInput0V/common voltage.
SDAI2C Data SignalBi-directionalBi-directional data line. Voltage should not exceed power supply (e.g. 3.3V).
SCLI2C Clock SignalInputMaster-controlled clock signal. Voltage should not exceed power supply (e.g. 3.3V).


Optional Features

The Qwiic Flex Glove controller has onboard I2C pull up resistors; if multiple sensors are connected to the bus with the pull-up resistors enabled (which they most likely will be if you're creating a full set of gloves), 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 cutting the traces on the corresponding jumpers highlighted below.

I2C Pullup

The I2C address of the board can be changed using the jumpers on the back of the board. The address selection pin is connected to the center pad of each jumper, the below table shows the addresses available when the address selection pin is tied to each of the 4 available pads.

PinAddress
GND0x48 (Default)
VCC0x49
SDA0x4A
SCL0x4B

The location of the jumpers is shown in the below image.

Address Jumpers

The holes in the bottom corners of the board are used for sewing the board into the gloves of your choice.

Sewing holes

Make sure you don't crease the flex sensors as this will break the sensor!
