Appallingly small Teensy 3.x add-on board with 16 Mbytes of fast serial flash memory using an SPI communications interface. Pin out and 5 mm x 6 mm WSON package common to Spansion and Winbond flash chips so either can be used. Board mounts onto the non-USB end of Teensy 3.x or Teensy-LC. Added bypass capacitor and CS pullup resistor.

Appallingly small Teensy 3.x add-on board with 128 Mbytes of fast serial flash memory using an SPI communications interface. BGA-24 package Spansion S70FL1GS flash chip. Board mounts onto the non-USB end of Teensy 3.x or Teensy-LC. Designed so it does not interfere with the I2C port on pins 16/17 of the Teensy 3.1. Added CS pullup resistors.

Invensense’s latest digital MEMS microphone with 24-bit I2S serial data output in a smaller, higher S/N package.

Simple Teensy 3.1 add-on board to test the relative performance of various state-of-the-art MEMS pressure sensors. Included is Invensense’s 3.5 mm x 3.5 mm ICM20730 7-axis motion sensor with accel/gyro and embedded pressure sensor, Bosch’s 2.5 mm x 2 mm BMP280, ST Microelectronics' 2.5 mm x 2.5 mm LPS25H, and Measurement Specialties' 3 mm x 3 mm MS5637. Broken out are all interrupts (ICM20730 and LPS25H) and all I2C device address bits (ICM20730, BMP280, and LPS25H) to avoid address conflicts. Also broken out is the ICM20730 FSYNC pin to test electronic image stabilization.

Invensense’s bottom-ported MEMS digital microphone with an embedded ASIC which directly outputs 24-bit I2S serial data without the need of a CODEC. Board is intended as a standalone microphone for breadboarding.
