Product Description

RAK14004 WisBlock Keypad Module was designed to be part of a production-ready IoT solution in a modular way and must be combined with a WisBlock Core and a WisBlock Base module.

The RAK14004 module is designed as an IO extension module that allows to add a keypad and create a customized IoT solution. RAK14004 uses a matrix scanning technique to support more buttons with limited GPIO. The scan and keys control is performed by an ATMEGA328PB-AU MCU from Microchip. This module can be used in conjunction with RAK14009, RAK14010, or RAK14011 keypad modules. The maximum number of buttons supported is 8 x 8 = 64 buttons.
