Mouser appeals to makers with indoor sensor and audio pHATs from Pimoroni

Pimoroni was founded in 2012, designing and manufacturing breakout boards, kits and add-ons for Raspberry Pi and micro:bit. The company name – pronounced Pih-mo-row-knee, is based on ‘pirate, monkey, robot, ninja’ and the company’s mission is to make electronics accessible, and to spread knowledge and ideas.

The distributor has added the PIM486 Enviro for the Raspberry Pi board. It is for indoor monitoring, to measure pressure, temperature, humidity, noise and light levels. The assembled board enables engineers to push collected data to an external server, which can be remotely accessed from any location.

It is equipped with a Bosch BME280 humidity and pressure sensor. The compact, low power sensor has rapid response times, says Mouser and supports performance requirements for context awareness applications. There is also a Lite-On LTR-559ALS-01 optical sensor which is an integrated I²C digital light and proximity sensor with a built-in emitter. The PIM486 Enviro also has a Knowles SPH0645LM4H-B MEMS microphone. The module is compact, measuring 65 x 30 x 8.5mm for use with the Raspberry Pi Zero and compatible 40-pin Raspberry Pi models. It ships with a Python library.

The second addition to Mouser’s new product introduction scheme is the company’s Pirate audio pHAT boards (pictured). They combine audio, playback control and LCD screen and are compatible with all Raspberry Pi models with a 40-pin GPIO header. The boards for streaming or local audio files (e.g. MP3, FLAC) ship with custom Pirate Audio software and a simple installer. The product range includes a speaker board, stereo amplifier board, line-out board and headphone amp board. The PIM485 Audio Speaker board features a miniature mono 1W speaker, Maxim’s MAX98357A I²S DAC, amplifier, high-resolution display, and playback control buttons. For a little more power, the PIM484 3W stereo amp combines two MAX98357A DACs to provide 3W output per channel. Push-fit terminals are incuded to connect external speakers and the board includes a switch for stereo/mixed-down mono modes.

The PIM483 audio line-out board allows developers to upgrade existing hi-fi amps, speakers and powered monitors with clean 24-bit/192kHz digital audio. The board is based on a Texas Instruments PCM5100A DAC and delivers line-level digital audio over I²S and includes a 3.5mm stereo jack. The PIM482 headphone amp is based on a PAM8908 stereo headphone amplifier from Diodes and a PCM5100A DAC from Texas Instruments. The board integrates a 3.5 mm stereo jack and a low-gain/high-gain switch to create a hackable po
