This is a product board, not a development board
This board needs some up grades. Pin 7 on the chip needs a cap. to gnd to get reduced noise and distortion. Pads to pins 1 & 8 would allow changes to the gain 20 - 200. Board set at gain of 20 as shipped. A pad from pin 6 would allow a bigger filter cap. The one shipped is the smallest one that could work. There is a diode in-line with V+, which means the lowest voltage allowed to the board is 4.5 V. Chip then gets 3 - 4 V. This also means the output power is lower, because the chip voltage is lower than the board.I should have read the description better, not what I thought I would get.

Worked perfectly for my project
Needed to increase the dynamic microphone output to build an adapter for my Heil Pro-7 headset to work on a rig that Heil does not have an adapter for. Small size fit inside the break out box that I built.73 de KV4ZY

Did not work for me at all
Tried to feed an audio playback module into alp and no sound from either one.

Tiny things!
They do work well for driving small speaker projects, and will make great pre-amps.

Cheap and easy. Needs a cap.
Works well for a small Bluetooth project. I need a capacitor apparently as I have whine in speakers
