The MonkMakes Air Quality Kit for Raspberry Pi is based around the MonkMakes Air Quality Sensor board. This add-on for the Raspberry Pi measures the quality of the air in a room (how stale the air is) as well as the temperature. The board has a display of six LEDs that display the air quality and a buzzer. Temperature and air quality readings can be read by your Raspberry Pi, and the buzzer and LED display can also be controlled from it.
The Air Quality Sensor board, plugs directly into the back of a Raspberry Pi 400, but, can also be used with other models of Raspberry Pi, using the jumper wires and GPIO template included in the kit.
Specifications:
This board uses the CCS811 VOC sensor IC and a TMP235 temperature sensor. It also has a rudimentary display and a buzzer.
The board uses a bi-directional UART interface to communicate with the Pi. The board is designed for use with the Raspberry Pi 400, but also works with other models of Raspberry Pi using the jumper wires included in the kit.

Make the Raspberry Pi Pico the core of your new robotics project with the Kitronik Compact Robotics Board for Raspberry Pi Pico.
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 3V and GND connections to power the connected Pico. This removes the need to power the Pico separately. The 3V 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 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), with full forward, reverse, and stop control, and 8 servos.
- 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.
- Additionally, the board 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 broken out to solder pads, allowing external devices to be powered.
- Code it with MicroPython via an editor such as the Thonny editor.

Powering the Maker Pi 2040
There are three ways to supply power to the Maker Pi RP2040 - via USB (5V) socket, with a single cell LiPo/Li-Ion battery or through the VIN (3.6-6V) terminals. However only one power source is needed to power up both controller board and motors at a time. Power supply from all these power sources can all be controlled with the power on/off switch onboard.

Maker Pi RP2040 features all the goodness of Cytron's Maker series products. It too has lots of LEDs useful for troubleshooting (& visual effects), is able to make quite some noise with the onboard piezo buzzer and comes with push buttons ready to detect your touch.

The W5100S-EVB-Pico pinout is directly connected to the GPIO of RP2040 as shown in the picture above. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5100S inside the board. These pins enable SPI communication with W5100S to use the Ethernet function.
If you are using the Ethernet function, these pins cannot be used for any other purpose.
The RP2040 GPIO used inside W5100S-EVB-Pico is as follows.
I/O | Pin Name | Description |

1. Standard stripboard is great for prototyping and building circuits but it can be time consuming to use with components with certain pin configurations such as IC's. As much time has to be spent breaking tracks to ensure no shorts exist across opposite component pins. This board gets around that problem by having isolated groups of pins.
2. Solderable PCB breadboards, single-sided PCB, matches breadboards with Power Rails.
These boards are especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place.

WARNINGS
• Any external power supply used with Raspberry Pi Compute Module 4 shall comply with relevant
regulations and standards applicable in the country of intended use.
• This product should be operated in a well-ventilated environment, and if used inside a case, the case should not be covered.
• Whilst in use, this product should be placed on a stable, flat, non-conductive surface, and should not be contacted by conductive items.
• The connection of incompatible devices to Compute Module 4 may affect compliance, result in damage to the unit, and invalidate the warranty.
• All peripherals used with this product should comply with relevant standards for the country of use
and be marked accordingly to ensure that safety and performance requirements are met. These
articles include but are not limited to keyboards, monitors, and mice when used in conjunction with the Compute Module.
• The cables and connectors of all peripherals used with this product must have adequate insulation so that relevant safety requirements are met.
SAFETY INSTRUCTIONS
To avoid malfunction or damage to this product, please observe the following:
• Do not expose to water or moisture, or place on a conductive surface whilst in operation.
• Do not expose to heat from any source; Raspberry Pi Compute Module 4 is designed for reliable operation at normal ambient temperatures.
• Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board
and connectors.
• Whilst it is powered, avoid handling the printed circuit board, or only handle it by the edges to minimise the risk of electrostatic discharge damage.

Overview

Raspberry Pi Compute Module 4 harnesses the compute power of the popular Raspberry Pi 4 Model B, bringing it to a smaller form factor suitable for integration into products. Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, dual camera interfaces, and PCIe Gen 2 x1 interface. The optional dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0 have modular compliance certification. This allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Either the onboard antenna or an external antenna kit can be used.
Compute Module 4 has optional onboard eMMC of 8GB, 16GB or 32GB.
