A6 GSM / GPRS Module Development...
This electret microphone module is a high-quality amplifier. It has a single/dual input of 20dB. This is useful in recording sounds, applicable to portable audio devices such as laptops, cell phones, and handheld computers.
This audio converter converts the digital signal (optical or coaxial) in a stereo analog signal. The signal received on the input SPDIF (TOSLINK) or coaxial output is converted and transmitted to stereo L / R RCA jacks standard.
The adapter is designed to transfer the HDMI signal from a computer, laptop, PS3, Xbox etc. to a VGA signal and display at high resolutions such as monitors, LCD TVs, projectors, etc. This is a portable adapter that makes transfer from HDMI HD in to VGA output.
This small mono amplifier is surprisingly powerful - it can deliver 3.2 watts of power to a 4 ohm impedance speaker (5V power @ 10% THD). Inside the miniature chip is a Class D controller, capable of running from 2.7V to 5.5VDC. Since the amp is a class D, it's incredibly efficient - making it perfect for portable and battery-powered projects.
MAX31865 RTD Platinum Resistance Temperature Detector PT100 to PT1000
Product Features : Supply voltage: 2.4V - 5.5V; Current consumption: 30mA; Integrated microphone on board; An integrated amplifier that can directly control an 8 ohm impedance loudspeaker and 0.5W power; Record and play buttons; It can record up to 16 seconds.
This slim little board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each.
A very powerful and easy to use sound module.
PCM5102A Audio Stereo DAC with 32-bit 384 kHz PCM Interface
FeatherWing Adafruit Music Maker is an enhanced version of the other FeafWing Adafruit products because it has a 3W amplifier integrated. This includes the VS1053, a coding / decoding chip that can decode a wide range of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, and WAV (PCM and ADPCM).
TPA6120 High Fidelity Stereo Headphone Amplifier Module
Adafruit Audio FX Mini Sound Board Module - WAV/OGG Trigger 16MB Flash
The ideal module to play sounds without the need for a microcontroller. Small and portable, at the touch of a button, will play the chosen sound. It is independent, all it needs is power supply between 3V and 5.5V.
3.5 mm 4-Pin Audio Cross-Over Adapter Cable, Black
3.5 mm plug to 2 x RCA sockets stereo audio cable, 0,2 m
The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's (MP3 is patented and costs $ to license, so this board uses the similar but not-patented OGG format, there's tons of free converters that will turn an MP3 into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of trigger type.
