Product User’s Manual – SKPS

5. PRODUCT SPECIFICATION AND LIMITATIONS

SKPS is designed to offer a compact and reliable PS2 Controller Converter for user. The

specifications are as listed below:

Label Definition Function

Power Input for

SKPS

External power source for SKPS, the typical voltage is

5V. Please ensure this 5V source is a stable supply.

Please do not use normal AC-DC adaptor to power it. It is

recommended to use linear regulator (7805) to provide

5V supply.

GND

Ground or negative Ground of power and signal.

SKPS UART

Receive signal

This is SKPS’s receiver pin, it should be interfaced to 5V

logic UART, no divider is necessary. This is an input pin

to SKPS. It should be connected to microcontroller’s

transmitter pin.

SKPS UART

Transmit signal

This is SKPS’s transmitter pin; it should be interfaced to

5V logic UART. This is an output pin from SKPS. It

should be connected to microcontroller’s receiver pin.

RESET

SKPS Reset pin

Reset pin of SKPS. It should be connected to a push

button to Gnd, or NPN transistor.

NOTE: SKPS can only be powered by either by PC through 4 way 2510 connector or

external power (5V). The 5V must be a stable supply. Any ripple higher that 5.5V will

spoil the controller on SKPS and it is not replaceable.
