Customer Reviews
Used these to build a nice macropad for my computer - worked great. These standard little matrix membrane keypads are perfect for prototype projects before you want to invest in a mechanical keypad
You might be able to get this cheaper from China but your going to half to wait a month. I got it in 2 days. Finished the prototype for the class project and now I'm studying Thermo. There is so much free info out there to support you in your projects with this guy if you're new. Have fun creating!
Excellent transaction
Used this keypad to mate with an ESP8266 onto my golf cart. Allows me to enter code to open/close two garage doors from the golf cart. Quality product.
