This audio adapter lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects with a Teensy 4.0 or Teensy 4.1 Microcontroller. | The audio chip connects to Teensy using 7 signals. The I2C pins SDA and SCL are used to control the chip and adjust parameters. Audio data uses I2S signals, TX (to headphones and/or line out) and RX (from line in or mic), and 3 clocks, LRCLK (44.1 kHz), BCLK (1.41 MHz) and MCLK (11.29 MHz). All 3 clocks are created by the Teensy. The SGTL5000 chip operates in "slave mode", where all its clock pins are inputs. | This Version 4.0 Rev. D works with Teensy 4.0 and Teensy 4.1 Microcontrollers only. | Includes 40-pin male and female headers that can be cut to the appropriate length and soldered onto the Audio Adapter and/or the mating Teensy microcontroller so they can be easily interconnected.connected | By soldering the male pins to one board and the female pins to the other, the boards can be easily disconnected for testing, troubleshooting, and prototyping. | Package includes the Teensy Audio Adapter 4.0, 1 40-pin male headers and 1 40-socket/pen female header.

HIGH-PERFORMANCE MICROCONTROLLER: Features an ARM Cortex-M7 processor at 600MHz (can be overclocked), with a NXP iMXRT1062 chip, the most powerful microcontroller available today | ARDUINO-COMPATIBLE: The Teensy is compatible with the Arduino IDE programming environment as well as many of the existing Arduino libraries, so it is easy to get programmed and running | RAM: 1024K RAM (512K is tightly coupled); 2048K Flash (64K reserved for recovery & EEPROM emulation) | MULTIPLE I/O: 2 USB ports, both 480 MBit/sec; 3 CAN Bus (1 with CAN FD); 31 PWM pins; 40 digital pins, all interrupt capable; 14 analog pins, 2 ADCs on chip; 2 I2S Digital Audio | LOCKABLE PROGRAM CODE OPTION: The LOCKABLE version of the Teensy 4.0 is suitable for commercial products and secure applications to protect your program code from unauthorized access and copying. When code security is not required, we recommend the STANDARD NON-LOCKABLE version. | TEENSY 3.2 COMPATIBLE: Same size and shape as the Teensy 3.2 and retains compatibility with most of its pin functions
