  • Adafruit Feather RP2040

    Adafruit Adafruit Feather RP2040

    Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all thier native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).Technical Specifications Measures 2.0 x 0.9 x 0.28' (50.8 x 22.8 x 7 mm) without headers soldered in Light as a (large?) feather – 5 grams RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V logic and power 264 KB RAM 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage.

  •  -29% Adafruit Zero Spy Camera for Raspberry Pi Zero (160 Degree Focal Angle)

    Adafruit Adafruit Zero Spy Camera for Raspberry Pi Zero (160 Degree Focal Angle)

    1 review

    Is your house haunted? Or, rather, are you convinced that your house is haunted but have never been able to prove it since you've never had a camera that integrated with your Raspberry Pi Zero but was still small enough that the ghosts wouldn't notice it? Luckily, the spy camera for Raspberry Pi Zero is smaller than a thumbnail with a high enough resolution to see people, ghosts, or whatever it is you're looking for. It's about the size of a cell phone camera – the module being just 8.6 x 8.6 mm – with only a 2' cable, so you can create an extra compact and sneaky little spy cam. It has a 160-degree focal angle for a very wide/distorted fisheye effect that's great for security systems or watching a big swath of the living room or roadway. Like the Raspberry Pi camera board, it attaches to your Raspberry Pi Zero v1.3 or Zero W by way of the small socket on the board's edge closest to the 'PWR in' port. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data. The camera is connected to the BCM2835 processor on the RPi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi. The ribbon cables are compatible with both the RPi Zero v1.3 and RPi Zero W. The sensor itself has a native resolution of 5 megapixels and has a fixed focus lens onboard. It has similar specs as the original RPi camera, but is not as high-res as the new RPi camera v2! Specifications Camera Module Dimensions: 8.6 x 8.6 mm Lens Diameter: 10 mm Total Length: 60 mm Lens Focal Angle: 160 degrees Weight: 1.9 g

  • Adafruit 2.5 W Class D Mono Amplifier (PAM8302)

    Adafruit Adafruit 2.5 W Class D Mono Amplifier (PAM8302)

    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 V - 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. Features Output Power: 2.5 W at 4Ω, 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)

Buy a Raspberry Pi

What is Raspberry Pi? Why do you need a Raspberry Pi board? What are the benefits?

Raspberry Pi is a minicomputer or a so-called Single Board Computer (or SBC for short) from the Raspberry Pi Foundation from Cambridge (GB). In a single-board computer, all important components such as the processor, RAM and GPU are mounted on one board.

The foundation published the first Raspberry Pi version in 2012 with the idea of promoting computer science as a school and study subject. The main goal to achieve this was a retail price of $35 that should be affordable for everyone.

Elektor also wanted to arouse early interest in computer science and electronics among pupils and students. As an official Raspberry Pi reseller, Elektor has direct personal contact with the Raspberry Pi developers in Cambridge and with the actual intellectual father of the Raspberry Pi, Eben Upton. Elektor not only offers official Raspberry Pi hardware, but also offers its customers interesting first-hand projects, reviews, tutorials and specialist books. Elektor thus occupies a special position among all Raspberry Pi dealers.

Buying a Raspberry Pi board: what can you do with it?

What makes the Raspberry Pi so special? This small, full-fledged, credit card-sized computer has won the hearts of software and hardware developers around the world and continues to reinvent itself with each new hardware version. With more than 20 million boards sold, Raspberry Pi has turned the electronics world upside down. It doesn't matter if you are a beginner or a professional developer, Raspberry Pi is the universal tool for every electronics technician! Use the Raspberry Pi for your own developments, control your smart home products with it or use it as a media player in the living room for streaming. Raspberry Pi cuts a fine figure in every area. The application possibilities are almost endless. The steadily growing community develops fun, but above all useful projects that are easy to make yourself.

Smart Home projects with Raspberry Pi

Today, a Smart Home is one of the most used applications for the Raspberry Pi. The reason for this is logical because a Smart Home provides more comfort in the home and makes saving on energy costs easy. Below you will find three of the most commonly used applications of Raspberry Pi in a Smart Home environment

Home automation system

The Raspberry Pi can be used to build a home automation system that allows you to perform tasks automatically. This includes controlling lighting, heating, entertainment and air conditioning.

Home monitoring

Home monitoring is a system that uses sensors to take measurements of your home environment and transmit this information to a central device. The system can take measurements of: temperatures, humidity, light intensity and movement. Use home monitoring to monitor your home environment, allowing you to use alarm systems, security cameras and other devices to protect your home.

A good example of this is when you close your roller shutters automatically as soon as it threatens to get too hot. This way you can easily restore the heat in your home.

Smart switches

A smart switch is a device used to turn electrical appliances on and off remotely. It is a wireless device that is connected to your home network and can be controlled with a mobile app, a remote control or a voice assistant.

A good example of smart switches combined with Raspberry Pi is turning off lights when you watch a movie via Kodi. You can even go so far that when you pause the movie, the lights come back on.

Buy your Raspberry Pi from Elektor
