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

The Picon Zero is an add-on for the Raspberry Pi. It has the same size as a Raspberry Pi Zero, making it ideal to function as a pHat. Of course, it can be used on any other Raspberry Pi via a 40-pin GPIO connector.As well as two full H-Bridge motor drivers, the Picon Zero has several Input/Output pins giving you multiple configuration options. That allows you to easily add outputs or analog inputs to your Raspberry Pi without any complicated software or kernel-specific drivers. At the same time, it opens up 5 GPIO pins from the Raspberry Pi, and it provides the interface for an HC-SR04 ultrasonic distance sensor.The Picon Zero comes with all components, including the headers and screw terminals, fully soldered. Soldering isn't required. You can use it right out of the box.Features pHat format PCB: 65 mm x 30 mm Two full H-Bridge motor drivers. Drive up to 1.5 A continuously per channel, at 3 V - 11 V. Each motor output has both a 2-pin male header and a 2-pin screw terminal. The motors can be powered from the Picon Zero's 5 V or an external power source (3 V - 11 V). The Picon Zero's 5 V can be selected to be from the Raspberry Pi's 5 V line, or a USB connector on the Picon Zero. That means that you can effectively have 2 USB battery banks: one to power the servos and motors on the Picon Zero and the other to power the Pi. 4 Inputs that can accept up to 5 V. These inputs can be configured as follows: Digital inputs Analog inputs DS18B20 DHT11 6 Outputs that can drive 5 V and be configured as: Digital Output PWM Output Servo NeoPixel WS2812 All Inputs and Outputs use GVS 3-pin male headers. 4-pin female header that connects directly to an HC-SR04 ultrasonic distance sensor. 8-pin female header for Ground, 3.3 V, 5 V, and 5 GPIO signals allowing you to add their additional features. Hardware ConfigurationPicon Zero has two jumpers for setting the hardware configuration. Ensure that you have placed them in the correct position. JP1 – Board 5 V Selector. This jumper selects where to get the 5 V power from for the Picon Zero Outputs. The options are: Jumper at the top between RPI and 5 V. The 5 V power for the board is taken from the Raspberry Pi pins on the GPIO connector. Because of the low power output devices and the 5 V motors, all devices can be powered with a single 5 V power input. Jumper at the bottom between USB and 5 V. The 5 V power is taken from the microUSB connector on the Picon Zero. Useful for higher power output devices, since you can provide extra power through the micro-USB connector on the board JP2 – Motor Power Selector. This jumper selects where the motors get the power. The two options here are the following: Jumper at the top between MotorPower and Vin. The motors are driven via the 2-pin screw terminal. The voltage can be between 3 V and 11 V. Useful for motors that require a voltage different from 5 V, or that require more current than is available on either of the USB input connectors Jumper at the bottom between 5 V and MotorPower. The motors are driven from the board's 5 V. Raspberry Pi ConfigurationThe Picon Zero is an I²C device. Make sure your Raspberry Pi is set up correctly to use I²C and SMBus: sudo apt-get install python-smbus python3-smbus python-dev python3-dev sudo nano /boot/config.txt Add the following lines at the end of the file dtparam=i2c1=on dtparam=i2c_arm=on Press Ctrl-X and use the default prompts to save sudo reboot Plugin the Picon Zero onto the Pi and run i2cdetect -y 1If everything goes well, you will see the Picon Zero showing up as address 22 as shown below:

Plug a reader into the headers, use a Qwiic cable, scan your 125kHz ID tag, and the unique 32-bit ID will be shown on the screen. The unit comes with a read LED and buzzer, but don't worry, there is a jumper you can cut to disable the buzzer if you want. Utilizing SparkFun's handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1'-spaced pins if you prefer to use a breadboard. Utilizing the onboard ATtiny84A, the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card, attaches a timestamp to it, and puts it onto a stack that holds up to 20 unique RFID scans at a time. This information is easy to get at with some simple I²C commands.
