use another board besides tx1

now i will use tx1 from technical and commercial view what is your recommendation about connect on tx1 actuator or led or motor.
there is another opinion is to make another board to connect previous items on it and communicate with tx1 with uart peripheral ?
by the way i have short place to put my boards
Please answer me and what i do and why?
thanks in advance.

It depends on the connection request of the peripheral device you chose. TX1 has GPIO/I2C/UART etc. interface for external devices control and communication.
