🔢 RobotDyn 3x4 Button Keypad Module with Analog Output - Ideal for Arduino, Raspberry Pi, and STM32 Review

You need to adjust the trigger voltage because the product specifications are not correct. Other than that I've never seen anything like it on Revain so I'll buy it again if the need arises.

Pros: - Works. Tested with Arduino UNO and Raspberry Pi (with ADC). Cons: The mounting holes on the board are too close to the buttons, making assembly difficult (for an amateur like me). slightly on the central axis - the connector pins are on the front of the board. To me it would make more sense if they were at the rear so you can flush mount them. So, all my problems were with the mount. If I had a mechanical workshop or a 3D printer, these problems would go away. But I do not know. If it…

The product description says that the keys are two-piece with caps. Hats are not included. The product arrived with the packaging already open. NCaps was nowhere in the package. Also, this item costs less than $2 on the manufacturer's website.

Great Arduino button board for the price. The keys are a bit noisy but responsive. The size was larger than I expected (that's a plus) - the buttons are arranged so that they aren't cramped. A hard case would be super handy. Really easy to add to any project - just connect "Output" to an analog pin and read the value.
