Figure 12. mikroBUS socket connector pinouts
The LPC55S36-EVK mikroBUS socket supports different types of add-on boards, called
click boards
, which are plug and play
solutions to add new functionality to the board design. A click board has a pair of 1x8 pin headers that connect to the two
receptacles of a mikroBUS socket.
MikroElektronika (MIKROE) is one of the manufactures of click boards. You can find details of some example click boards for
LPC55S36-EVK mikroBUS socket at
MIKROE website .
2.13 Motor control and Arduino sockets
The LPC55S36-EVK board has two Arduino sockets, each with four connectors (2x6, 2x8, 2x10, and 2x8 position receptacles).
In each socket, the two 2x8 position receptacles are placed diagonally opposite to each other. Each socket is pin-compatible with
an Arduino Uno revision 3 (R3) board. Each socket allows communication with one FlexPWM module of motor control subsystem
of the target MCU (LPC5536).
2.13.1 Motor 1 c unused MCU pin socket
The Motor 1 c unused MCU pin socket allows communication with the following modules/pins of the target MCU:
• FlexPWM0 module of motor control subsystem
• Analog-to-digital converter (ADC) modules, ADC0 and ADC1
• Digital-to-analog converter (DAC) modules, DAC0 and DAC1
• Some of the unused MCU pins
The socket includes the following four connectors:
• J13 (2x6 position receptacle)
• J10 (2x8 position receptacle)
• J9 (2x10 position receptacle)
• J12 (2x8 position receptacle)
The figure below shows the pinouts of Motor 1 c unused MCU pin socket connectors. Odd pins (inner side pins) of the
socket are used for motor control. Even pins (outer side pins) of the socket are either connected to unused MCU pins or used for
other purposes.
