Reliable signal multiplexing
I am using this in a custom data acquisition setup to switch between multiple thermocouple amplifiers. The signal integrity remains high, and crosstalk is negligible at the speeds I am operating. Highly recommended for industrial prototyping.

Fast switching, no issues
Integrated this into a robot sensor array. The switching speed is impressive, allowing us to scan all 16 proximity sensors multiple times per second without slowing down the main control loop. Very happy with this purchase.

Perfect for expanding Arduino inputs
This module worked flawlessly with my Arduino Uno project. I needed to read 12 different sensors but only had a few analog pins available. The 74HC4067 handled the switching instantly without any noticeable lag. The pinout is clearly labeled, making wiring very straightforward.

Great value, solid build
The board quality is excellent for the price. The soldering on the headers was clean. I deducted one star only because the included documentation was minimal, but finding example code online for the 74HC4067 is very easy. Works great with Raspberry Pi GPIO as well.

Essential for my capstone project
Saved my semester project! I needed to monitor battery voltages across a 16-cell pack. This board allowed me to do it with a single ADC pin on my microcontroller. It's compact and fits perfectly into my enclosure.

Good for educational kits
We bought several of these for our electronics workshop. They are robust enough to handle students plugging and unplugging wires repeatedly. The logic levels work perfectly with both 3.3V and 5V systems, which is crucial for our mixed inventory of boards.
Q: Is there an enable pin to disable all channels simultaneously?
A: Yes, the module exposes the Enable (E) pin. Pulling this pin HIGH will disable all switches, putting the common output/input into a high-impedance state.
Q: Can I use this for digital signals or only analog?
A: The 74HC4067 is a bidirectional switch, meaning it can pass both analog and digital signals seamlessly, provided the signal voltage stays within the supply voltage range.
Q: Can this board be used directly with a 3.3V microcontroller like the ESP32?
A: Yes, the 74HC4067 chip supports an operating voltage range of 2V to 6V, so it works perfectly with 3.3V logic levels found on ESP32, ESP8266, and similar boards.
Q: Does this module come with pre-soldered header pins?
A: Yes, the board arrives with the male header pins already soldered, ready for immediate insertion into a breadboard or connection via jumper wires.
Q: What is the maximum current each channel can handle?
A: Each channel can typically handle up to 25mA of continuous current. Please ensure your load does not exceed this limit to prevent damage to the IC.
