Listen to this good news - Adafruit now have an all in one digital audio amp breakout board that works incredibly well with the Raspberry Pi! If you're looking for an...

The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.

1/4 Watt ±1% Metal Film resistor commonly used for breadboarding and DIY electronics.

Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. Adafruit have a couple digital thermocouple amplifiers in the shop already...

The ADC Pi is an 8 channel 17 bit analogue to digital converter designed to work with the Raspberry Pi. The ADC Pi is based on two Microchip MCP3424 A/D converters each containing 4 analogue inputs. The MCP3424 is a delta-sigma A/D converter with low noise differential inputs.

The M5Stack Mini Weight Unit Load Cell Amplifier integrates an HX711, 24-bit A/D chip that is specifically designed for an electronic weighing device.

LM393 - 8 - Low power dual comparator

This is a 5g syringe of white heatsink compound (aka thermal grease, thermal paste, thermal goo). Use this whenever you’re connecting a component to a heatsink, it’ll really help to dissipate even more potentially damaging heat.

Digital potentiometer is also called "Digital Pot" in short. It is a kind of mixed signal IC, which is able to dynamically change the internal resistors through...

The module integrates MCP3432 A/D converter chip. The module can provide analog input function for Raspberry Pi and provide high accuracy analog input for Arduino.

Piezos make noise when you put an AC voltage across them: and the bigger the Vpp the louder they are. With your standard 3V logic microcontroller you can...
