OVERVIEW
2
Keys Keypad can be connected to any microcontroller or any interfacing kit
directly. KEY is a small keypad designed to data entries for microcontroller
board. The board has 4-pin header for 4-wire ribbon cable. By default the
switch status would be pulled up, every time you press a key the corresponding
switch header changes its state to the common header in the board.
FEATURES
- 2 keys.
- Connect to microcontroller's pin directly.
- 4-pin header.
- Input pins connected to Burgstick.
- With pull-up resistors.
- High quality PCB FR4 Grade with FPT Certified
