Description
The Downstream Board – Number Keypad (BL0138) is a useful tool as it allows one to enter numeric and textual data into the embedded system. All switches are designed with a push to make convention and are read by controlling the logic level of the columns to determine the state of the rows.
Only a single active switch on the keypad can be read at once.
To allow this E-blocks2 downstream board to work with a First Generation E-blocks upstream board, you will need the BL0113 conversion board.
