“Easy enough to use though I found that the zero noise mode took exclusive control of the sound device on rpi and prevented it's use by other software. Also you need to be careful when using with a pi4 as the Poe pins got the bottom of the PCB, I'm printing some 9mm standoffs to stop it dropping down and shorting out.”
“It is a DAC + amplifier that serves the same purpose as Hifiberry MiniAmp. Just that this one is half the price. The SMD header was quite a useful thing for me since it allowed me to snap it on top of an OnOff Shim soldered to a full-sized header and achieve quite a low stack of devices. But the killer feature of this one is the fact that there is a space to solder pins to break-out different GPIOs without needing to put a breakout header between the Pi Zero and the bonnet. In the pictures, you can see an internet radio using the i2c pins +5V and GND for the LCD; Different GPIOs (5,6,12), 3V and GND for one of the rotary encoders that works as "volume" with the button being MUTE; and the GPIOs 23 and 24 and the GPIO 17 through the OnOff shim button, 3V and GND (through the OnOff shim button's ground). This allows the second rotary encoder to work as MENU, switch on the Radio and -- with a modified script -- switch off the radio after shutdown. The shutdown trigger is achieved differently, by pressing the MENU switch for more then 3 seconds, and not by the daemon that the OnOff shim install script normally instals.”
“Not very easy to set up out the box. Been trying for a couple of days not having much joy. A lot of looking on the website until I get it working I would not recommend”
“I used this with an ESP32 module and it worked a treat, see the attached image of my prototype board - the speaker bonnet is intentionally mounted upside down. I am getting extremely clear sound from this and would highly recommend it!”
“Purchased this for using an open-source AI assistant. A little crackly in places depending on the volume one has it at, or the software relating to its use. However, great hat to have for the Zero.”
