Mini Active Buzzer

Works as a standard active buzzer or you can apply PWM to play tiny, bleepy tunes. Ahoy!

Connect a voltage (4-8v) to the pins to make Dumb Noise (tm) or use a PWM from a microcontroller to change the tones - check out this Tom's Hardware article for how to play tunes using a Raspberry Pi Pico!

It's got sturdy, labelled pins for connecting to jumper jerky or poking into a breadboard. The specs list the minimum voltage as 4V, but we found it worked fine with 3.3V from a microcontroller. Note that you need to connect it up with the right polarity for it to make noise, even if you're planning on going down the PWM route.

Works really well. Have to say that I might get some 1mm as the 0.5mm is quite thin for my needs (mainly wiring between a uC PCB and I2C devices with single core wire). I guess the 0.5mm would be more appropriate for soldering surface mount items.

This solder is good if your joint location is not a large copper plane, in that case make sure to heat the surface adequately before applying the solder and you'll be fine.

I tried the 0.5mm but prefer this 1mm. What I do need is a new iron more suitable for lead free solder.... Another good product from Pimoroni.

Takes a bit of getting used to if you're used to lead solder. Dispatched in good time and worked well to solder a GPIO header on to a Raspberry Pi Zero.

I hope other people will become aware of fair supply chains that can be developed within the ICT and electronics industries. Use of this product will be a small step towards a fairer supply chain.
