IQaudIO DigiAMP (IQaudio Digi Amp )

Description:

DigiAMP is a HAT compliant add on accessory for the Raspberry Pi. DigiAMP uses the Texas Instruments TAS5756M PowerDAC to deliver direct connection to PASSIVE stereo speakers at up to 2x35wpc with variable output. Ideal for a Pi based HiFi. DigiAMP can be connected to the Raspberry Pi A /B /RPi2/RPi3 or RPi4's 40way pin header without any additional soldering. DigiAMP must be powered from an external supply and requires a 1 2 to 24DC power source to
operate. DigiAMP s barrel connector is 5.5mmx2.5mm. DigiAMP has been designed to provide power to the Raspberry Pi and DigiAMP combination in parallel, delivering 5.1v 2.5Amp to the Pi.

DO NOT APPLY POWER TO THE RASPBERRY PI’s OWN POWER INPUT WHEN USING DIGIAMP .

The amplifier is by default muted at power on (mute LED lit). The mute state LED is under software
control (Raspberry Pi GPIO22).

Raspberry Pi Sense HAT (Sense Hat)
Description:

The Sense HAT is an add-on board for Raspberry Pi, made especially for the Astro Pi mission! It’s going to the International Space Station in December 2015 – and is now available to buy from PiShop.

The Sense HAT has an 8×8 RGB LED matrix, a five-button joystick and includes the following sensors:

  • 3D Gyroscope
  • Accelerometer (Yaw, Pitch & Roll)
  • Magnetometer
  • Temperature
  • Barometric Pressure
  • Humidity

The Raspberry Pi Foundation have also created a Python library providing easy access to everything on the board.

Sensing Elements Technical Specification:

Pressure / Temperature (ST Micro LPS25H)
– 24-bit pressure measurement resolution (260hPa to 1260hPa)
– 16-bit temperature measurement resolution (0-125°C)
Datasheet

Humidity / Temperature (ST Micro HTS221)
– 16-bit humidity measurement resolution (0-100% relative humidity)
– 16-bit temperature measurement resolution (0-60°C)
Datasheet

Acceleration/Gyroscope/Magnetic field (ST Micro LSM9DS1)
– 9 degrees of freedom (X, Y, Z independent axes for all sensors)
– ±16 g acceleration measurement range
– ±16 gauss magnetometer measurement range
– ±2000 dps (degrees per second) gyroscope measurement range
Each of these measurement channels has 16 bits of resolution.
Datasheet

All of these sensors have features for periodic sampling of sensor values, complete with internal FIFO storage. The LPS25H and HTS221 have maximum sample rates of 25 per second, the LSM9DS1 has a maximum sample rate of 952Hz

LED Matrix
The LED matrix is driven by a combination of a constant-current LED driver and an Atmel ATTiny88 running a custom firmware that delivers an 8×8 display with 15-bit resolution RGB colour. If you want to get into the gory details, the AVR firmware is available on Github.

Joystick
The Atmel is responsible for sampling the joystick. We didn’t have enough pins left on the Atmel to dedicate the five that we needed to sample the joystick axes independently, so they’ve been spliced into the LED matrix row selects. The joystick gets updated at approximately 80Hz, which is the scan rate of the LED matrix.

All of the sensors (and the base firmware for the Atmel) are accessible from the Pi over I2C. As a fun bonus mode, the SPI peripheral on the Atmel has been hooked up to the Pi’s SPI interface – you can reprogram your HAT in the field! We use this method to get the firmware into the Atmel during production test – and we leave it unprotected so you can substitute the stock firmware to get it to do whatever you want. Seriously. First person to turn this sensor HAT into a quadcopter controller HAT wins a cookie from me.
