This Matrix Keypad 3 X 4 has 12 buttons, arranged in a telephone-line 3x4 grid. The keys are connected into a matrix,hence only 7 microcontroller pins (3-columns and 4-rows) are required to scan the pad.
It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.

I had used a lots of LoRa module till now, but it's really the best among all of them! the 1262 is a great upgrade in terms of output power and configuration. we can configure the output power, bandwidth, spreading factor and a tons of other things, which are not possible to configure on previous modules. the radiolib library works preety good with it and it also supports rssi and snr like features, which are very crucial when you are seriously researching on antenna or range related works! that's why I eventually like this module more then ebyte LoRas. To me this is the best module in IN8 68MHz, which is completly legal and free to use in India upto 1W! And also thanks to thinkrobotics, I got it in just 1 working day, and your packaging was also too good! Love your service, and keep this modules available on your websight. Your pricing of this module is too good, and I'll buy many of these modules. Thank you!

Team is suppotive and solves all the queries .
The product is good and will surely help me in my project...looking forward for more trades with think robotics.
