New Adafruit and Pololu breakout boards and sensors

16 04 2014
MinIMU-9 v3 Gyro Accelerometer and Compass, L3GD20H and LSM303D Carrier The Pololu MinIMU-9 v3 is an inertial measurement unit (IMU) that packs an L3GD20H 3-axis gyro and an LSM303D 3-axis accelerometer and 3-axis magnetometer onto a tiny 0.8″ x 0.5″ board. An I2C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v3 board includes a voltage regulator and a level-shifting circuit that allows operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
AltIMU-10 v3 Gyro Accelerometer Compass and Altimeter - L3GD20H, LSM303D and LPS331AP Carrier The Pololu AltIMU-10 v3 is an inertial measurement unit (IMU) and altimeter that features the same L3GD20D gyro and LSM303D accelerometer and magnetometer as the MinIMU-9 v3, and adds an LPS331AP digital barometer. An I2C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The board operates from 2.5 to 5.5 V and has a 0.1″ pin spacing.

GA1A12S202 Log-scale Analog Light Sensor Upgrade a project that uses a photocell with the GA1A12S202 analog light sensor. Like a CdS photo-cell, the sensor does not require a microcontroller, the analog voltage output increases with the amount of light shining on the sensor face. This sensor has a lot of improvements that make it better for nearly any project.
Adafruit Motor/Stepper/Servo Shield for Arduino Kit V2.0 The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. Adafruit have upgraded the Adafruit Motorshield kit V2 to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but with many added improvements
Adafruit Perma-Proto Half-sized Breadboard PCB Single This proto-board is the PCB you always wish you had, but never realized it! We took the basic layout of a half-sized breadboard and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you’re familiar with, to make transferring components easy. The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary.
Electret Microphone Amplifier MAX9814 with Auto Gain Control Add an ear to your project with this well-designed electret microphone amplifier with AGC. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplifying electret microphones in situations where the loudness of the audio isn’t predictable.
Thermocouple Amplifier with 1-Wire Breakout Board MAX31850K Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. So far we’ve carried the very nice MAX31855 which is an SPI interface thermocouple amplifier. The ‘855 is great but if you have a lot of thermocouples to measure it isn’t terribly easy to use. That’s why we are also carrying the new 1-Wire Breakout Board MAX31850K thermocouple amp which can have any number of breakouts on a single shared I/O line.
Fast Vibration Sensor Switch (Easy to trigger) The “poor man’s” accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to make contact. So, when there’s motion, the two pins will act like a closed switch.
SI1145 Digital UV Index, Infrared and Visible Light Sensor Remember when you were a kid and there was a birthday party at the pool and your parents totally embarrassed you by slathering you all over with sunscreen and you were all “MOM I HAVE ENOUGH SUNSCREEN” and she wouldn’t listen? Well, if you had this UV Index sensor connected up to an Arduino you could have said “According to this calibrated SI1145 sensor from SiLabs, the UV index right now is 4.5 which means I do not need more sunscreen” and she would have been so impressed with your project that you could have spent more time splashing around.
ChronoDot Ultra-precise Real Time Clock v2.1 This is the latest version of the ChronoDot RTC, an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC (TCXO).
