2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4x4 Key click 2 3 4. Essential features The design of 4x4 Key click inputs are read by a pair of connected 8-bit parallel-in serial- out shift registers allows for multiple key presses at the same time. You can press all 16 buttons simultaneously and each will be Turn the board upside down so that Turn the board upward again. Make sure registered. For ease of use, each button has the bottom side is facing you upwards. to align the headers so that they are silkscreen markings.
