Product description: SparkFun Qwiic Shield for Teensy - DEV-17119
An overlay created bySparkFunfor theTeensyseries modules. The board adds the ability to connect sensors and other accessories that use theQwiicconnector to the module. There aretwo straight connectorsandtwoQwiicangled connectors on the overlay. Modules that communicate via theI2Cinterface can be connected to the Qwiic connector. Qwiic ecosystem makes it much easier to connect sensors / modules to the main module with the same connector, no soldering is required and correct connection is assured. There is also a PROG button on the board, which serves the same function as the PROG button on the Teensy board. Included with the Qwiic overlay is a set of pins that you need to solder to the board yourself.
Qwiic allows you to connect sensors via the I2C bus, making prototyping faster and less error prone. Polarized connections mean you can't misconnect it. All Qwiic connectors have 4-pin leads with a 1 mm pitch.
Qwiic overlay comes with connectors for self soldering.Main features of the Qwiic Shield overlay for Teensy
- Compatible with Teensy 3.1 and Teensy 4.0 or LC
- 4 Qwiic connectors (two straight and two angled)
- PROG button - performs the same function as on the Teensy board
- I2C jumper
- 3.3 V line and GND
Qwiic connectors on the board
The Qwiic overlay for Teensy is equipped with four Qwiic connectors. Two straight ones are located on the edge of the board, and two angled ones are located in the middle of the board.
We also offeran extended versionfor Teensy 4.1, Teensy 3.6 and Teensy 3.5 modules.
SparkFun Teensy
The Teensy board is a small size module equipped with a 32-bitARM Cortex M4core microcontroller clocked at 72 MHz, 256 kB of Flash memory and 64 kB of RAM.Teensy 3.2has 34 input/output pins of which 12 PWM channels and 21 analog inputs, a DMA controller and popular communication interfaces: SPI, I2C, I2S, CAN. The Teensy pins operate at 3.3V.
