The PeakTech 1073 smart digital multimeter combines state-of-the-art technology with an impressive range of functions in a compact design. It measures voltages up to 600 V AC/DC, is CAT III certified and features True RMS for precise measurements with varying voltages. The integrated NCV voltage tester enables non-contact voltage detection, while the LIVE test reliably identifies phases and neutral conductors.
Thanks to the automatic search of the measuring function, you no longer need a rotary selector switch. The multimeter automatically recognizes what is being measured and adjusts itself accordingly. The 4000-digit LCD display with blue backlighting ensures clear readability of the measured values and changes to red when measuring ranges are exceeded or the NCV voltage tester detects a voltage.
In addition to the standard measurements for voltage, current (AC & DC), resistance, continuity, diode test and temperature, this multimeter also offers capacitance and frequency measurements.

This is a kit for a pan-tilt mechanism explicitly designed for Pixy2. After assembling the kit and connecting it to Pixy2, you'll be able to follow colored objects using the Pan/Tilt demo.
It includes two laser-cut plastic pieces for the base, two different servos for the pan and tilt axes, and all the mounting hardware and cable ties you will need to assemble.
Features
The pan-tilt mechanism for Pixy2 is redesigned, making it smaller and faster than the pan-tilt for the original Pixy.
All necessary hardware is included.
The pan-tilt base is attached directly to an Arduino with Arduino-compatible hole-pattern and includes stand-offs and fasteners.
Several pan-tilt demos are provided that can run using either Arduino, Raspberry Pi or stand-alone (no controller).

Here you can find the assembly guide!
This small mono amplifier is surprisingly powerful – able to deliver up to 2.5 W into 4-8 Ω impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0-5.5 V DC. Since the amplifier is a class D, it's very efficient making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection. There's even a volume trim pot so you can adjust the volume on the board down from the default 24 dB gain.
The A+ and A- inputs of the amplifier go through 1.0 µF capacitors, so they are fully 'differential' – if you don't have differential outputs, simply tie the Audio-pin to ground. The output is 'Bridge Tied' – that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250 KHz square wave PWM that is then 'averaged out' by the speaker coil – the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.
The amplifier comes with a fully assembled and tested breakout board, a header to plug it into a breadboard and a 3.5 mm screw-terminal blocks so you can easily attach/detach your speaker. Speaker is not included, we recommend using any 4 Ω or greater impedance speaker.

Output Power: 2.5 W at 4 Ω, 10% THD (total harmonic distortion), 1.5 W at 8 Ω, 10% THD, with 5.5 V Supply
50 dB PSRR (power supply rejection ratio) at 1 KHz
Filterless design, with ferrite bead + capacitors on output.
Fixed 24 dB gain, an onboard trim potentiometer for adjusting input volume.
Thermal and short-circuit/over-current protection
Low current draw: 4 mA quiescent and 0.5 mA in shutdown (due to pull-up resistor on SD pin)
