Works but needs config

Remember to enable internal pull-up resistors in your code. Once configured correctly it works fine, but beginners might struggle.

Solid Build

Keys feel clicky and responsive. Only reason for 4 stars is the silkscreen could be slightly larger for easier reading.

Perfect for Prototyping

Used this with an ESP32 project for menu navigation. The tactile feedback is excellent and the pins lined up perfectly with my breadboard.

Great Value

Bought five for various IoT controllers. They are compact and reliable. No issues with connectivity so far.

5 FAQ

Q: What is the pinout order?

A: The pins are arranged as VCC, GND, KEY1, KEY2, KEY3, and KEY4 from left to right when facing the components.

Q: Is a schematic available for download?

A: Yes, please visit the product wiki page linked in the description to download the PDF schematic and dimension files.

Q: Does this work with 3.3V logic levels?

A: Yes, this module is compatible with both 3.3V and 5V logic systems commonly used in MCU development.

Q: Can I stack this on top of a standard Arduino shield?

A: Yes, provided the shield does not obstruct the top side components. You may need stacking headers for clearance.

Q: Are pull-up resistors included on the board?

A: No, this module relies on the internal pull-up resistors of your microcontroller or external ones in your circuit.
