TS331ILT, Micropower low-voltage, rail-to-rail comparators, SOT-23-5

8-channel module with relays designed to work with the Raspberry Pi Pico. Has built-in power isolation. Perfect for industrial applications. Waveshare Pico-Relay-B

Air quality sensor module based on the SGP40 system. It uses CMOSens® technology by Sensirion and provides information on air quality. Waveshare SGP40 VOC Sensor

The Step-Down D24V6F5 Buck Voltage Regulator module gives the output voltage of 5V with a wide input voltage range of 7-42V and a maximum output current of 600 mA. Pololu 2107

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. SEN-13285

Double comparator with low power consumption in the TSSOP-8 housing. STMicroelectronics LM2903YPT

Module with 5V relay and timer. It allows the implementation of delayed switching on or off of the circuit with adjustable time in the range from 1 s to 100 s and from 1 s to 15 min.

Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min

CS-Mount lens. 25 mm focal length, 14° FoV, manual focus. Designed to work with the Raspberry Pi HQ camera. ArduCAM LN041

A4990 Dual Motor Driver Carrier

CS-Mount lens. 16 mm focal length, 24° FoV, manual focus and adjustable aperture. Designed to work with the Raspberry Pi HQ camera. ArduCAM LN050

BOB-11890

This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the disc. SEN-13332

SparkFun Cab-12970

Data logger with LPC2148 chip and microSD card support. The module is equipped with a microUSB connector, Li-Pol battery charger and a microSD card slot. SparkFun WIG-12772
