7. You can choose the check mode is no check, even check and odd check
8. You can set the data sending return time, the maximum can be set to 1000ms
9. Size: 44 * 35.6 * 5mm ( only board) 44* 35.6*11mmmm (with pin)
10. Weight: 7.6 grams (only board ); 9.2 grams (with pin)

This is a 2.54MM pin header version of the RS485 current collector, fully compatible with the terminal block version (N4AIB16 ).
The size is kept to a minimum while meeting the functional performance. It can be used as a core board and embedded into the base board.
