The MTi 1-series Shield Board has a
Micro USB connection that can be connected directly to a
USB port on a PC or laptop. Note: Make sure to disconnect any other power supply, as this will
overrule the USB connection.
The
Peripheral selection switch sets the interface configuration of the MTi 1-s module in the
socket. The switch connects the PSEL lines (Table Switch positions to enable interfaces on
Shield Board) to GND with a 5 k
Ω pull-down when set to ON. Otherwise, the PSEL lines are
pulled-up with a 100 k Ω resistor. The PSEL pins on the Arduino-compatible headers can be used
to overrule these lines.

PSEL1 PSEL0 Interface Comments
0 0 UART full-
duplex
This interface uses the flow control lines
RTS and CTS. The UART full-duplex
communications mode can be used
without hardware flow control. In this
case the CTS line needs to be tied low
(GND) to make the MTi device transmit.
0 1 UART half-
duplex
The UART itself is still full duplex but the
DE and nRE lines are used to control a
half-duplex transceiver
