LCD/Keypad extention for PCA10028

Adrian Eggenberger

I'm looking for some options to extend the PCA10028 with a keybord and a numpad. This would give great options to play around with passkey topics.

As the PCA10028 supports the Arduino pinout i guess that Arduino LCD/Keypads would be an option. But i didn't find a board that has keypad with buttons from 0 - 9 and an LCD.

Is there a recommended board? Has Nordic planed support for one of these boards?

Regards Adrian

    Hi Adrian, if you're just looking to experiment with passkeys it would probably be quicker to set up UART on the nRF51, and use the Virtual COM port on the pca10028 to input/output passkeys to a serial terminal on your computer. Having a keypad shield would certainly be useful in many cases though, so that's a good idea!

    There are multiple LCD extensions available. The PCA10028 has the same form factor as Arduino Uno. So LCD extensions that fit into Uno will fit into PCA10028 as well.

    Hi,

    Only a short roundup for this topic to close this question. I finally bought an Adafruit 2.8" TFT Touch Shield for Arduino w/Capacitive Touch. Until now I've got the TFT screen working. The screen update is really slow, because the LCD a lot of memory to fill over SPI transfers. For my purpose to visualize the status of my application and presenting keys for pairing it's doing ok.
