When Raspberry Pi 4's system on chip (SoC) achieves a certain temperature, it lowers its operating speed to protect itself from harm. As a result, you don't get maximum performance from the single board computer. Fan SHIM is an affordable accessory that effectively eliminates thermal throttling and boosts the performance of RPi 4. It's quite easy to attach the fan SHIM to Raspberry pi: fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! The fan can be controlled in software, so you can adjust it to your needs, for example, toggle it on when the CPU reaches a certain temperature etc. You can also program the LED as a visual indicator of the fan status. The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode. Features 30 mm 5 V DC fan 4,200 RPM 0.05 m³/min air flow 18.6 dB acoustic noise (whisper-quiet) Friction-fit header No soldering required RGB LED (APA102) Tactile switch Basic assembly required Compatible with Raspberry Pi 4 (and 3B+, 3A+) Python library and daemon Pinout Scope of delivery Fan SHIM PCB 30 mm 5 V DC fan with JST connector M2.5 nuts and bolts Assembly The assembly is really simple and almost takes no time With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts. Push the fan's JST connector into the socket on Fan SHIM. Software With the help of Python library you can control the fan (on/off), RGB LED, and switch. You'll also find a number of examples that demonstrate each feature, as well as a script to install a daemon (a computer program that runs as a background process) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.

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). 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. No EEPROM Tons of GPIO! 21 x GPIO pins with following capabilities: Four 12 bit ADCs (one more than Pico) Two I²C, Two SPI and two UART peripherals, one is labeled for the 'main' interface in standard Feather locations 16 x PWM outputs - for servos, LEDs, etc The 8 digital 'non-ADC/non-peripheral' GPIO are consecutive for maximum PIO compatibility Built in 200 mA+ lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking RGB NeoPixel for full color indication. On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I²C devices with no soldering! Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code) 3.3 V Power/enable pin Optional SWD debug port can be soldered in for debug access 4 mounting holes 24 MHz crystal for perfect timing. 3.3 V regulator with 500mA peak current output USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging RP2040 Chip Features Dual ARM Cortex-M0+ @ 133 MHz 264 kB on-chip SRAM in six independent banks Support for up to 16 MB of off-chip Flash memory via dedicated QSPI bus DMA controller Fully-connected AHB crossbar Interpolator and integer divider peripherals On-chip programmable LDO to generate core voltage 2 on-chip PLLs to generate USB and core clocks 30 GPIO pins, 4 of which can be used as analog inputs Peripherals 2 UARTs 2 SPI controllers 2 I²C controllers 16 PWM channels USB 1.1 controller and PHY, with host and device support 8 PIO state machines Comes fully assembled and tested, with the UF2 USB bootloader.

The Robotics Board features 2 Dual H Bridge Motor Driver ICs. These are capable of driving 2 standard motors or 1 stepper motor each, with full forward, reverse, and stop control. There are also 8 servo outputs, capable of driving standard and continuous rotation servos. They can all be controlled by the Pico using the I²C protocol, via a 16 channel driver IC. The IO break out provides connections to all the unused pins on the Pico. The 27 available I/O pins allow other devices, such as sensors or ZIP LEDs, to be added to the board. Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board and there is also a green LED to indicate when the board has power. The board then produces a regulated 3.3V supply which is fed into the 3 V and GND connections to power the connected Pico. This removes the need to power the Pico separately. The 3 V and GND pins are also broken out on the header, which means external devices can also be powered. To use the robotics board, the Pico should be firmly inserted into the dual row pin socket on the board. Ensure the Pico is inserted with the USB connector at the same end as the power connectors on the robotics board. This will allow access to all of the board functions and each pin is broken out. Features A compact yet feature-packed board designed to sit at the heart of your Raspberry Pi Pico robotics projects. The board can drive 4 motors (or 2 stepper motors) and 8 servos, with full forward, reverse, and stop control. It also features 27 other I/O expansion points and Power and Ground connections. The I²C communication lines are also broken out allowing other I²C compatible devices to be controlled. This board also features an on/off switch and power status LED. Power the board via either a terminal block or servo style connector. The 3V and GND pins are also broken out on the Link header, allowing external devices to be powered. Code it with MicroPython or via an editor such as the Thonny editor. 1 x Kitronik Compact Robotics Board for Raspberry Pi Pico Dimensions: 68 x 56 x 10 mm Requires Raspberry Pi Pico board

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
