Page 3: Chapter 1 Servo Motor Kit
Chapter 1 Servo Motor Kit The SMK (Servo Motor Kit) is designed for developer who wish to learn servo motor control and build their robot machine. It includes one servo motor driver daughter card and one servo motor. The motor driver card can drive 24 RC servo motors at most. The motor daughter card can be linked to the FPGA development kit via the 2x20 Pin GPIO connector. -

DC-Jack is used, please make sure the DC-Plug of the power source is meet required specification as shown in Figure 2-5. Terasic also provide the power supply, user can change the power supply from http://smk.terasic.com/buy. Note, do not provide power from J4 DC Jack and J1 2-pin power input at the same time. Otherwise, the board will be damaged. -

When driving servo motor, the PMW signals is sent from the host FPGA with IO standard 3.3V. The Host FPGA board should then provide 3.3V in the VCC3P for the daughter card to use it SMK User Manual www.terasic.com September 12, 2016... - Page 12 Figure 2-8. SOC_WARN_LED is a reserved signal. If users want the host FPGA to directly control the warning led, they can move 0 OMH from R316 to R317 as shown in Figure 2-9.
