Table 3: Connections on external power header (J100 in Figure 7)
Pin Description
1 VDDA
2 GND
3 GND
4 VDDIO
5 IOREF
The connections for
Arduino-compatible headers with a pitch of 2.54 mm (0.1 inch) are shown in Table
4. The MTi 1-series Shield Board does not support Arduino-compatible boards with an IOREF of 5V as
the maximum VDDIO is 3.6V for the MTi 1-s module. Therefore, the VDDIO is by default set to 3.3V.
This default VDDIO voltage can be overruled by placing a jumper on the external power header, but
only for voltages within the operational VDDIO range of the MTi 1-s module. For information on the
connections, refer to the pin description in Section 4.2. Refer to Table 6 on how to enable the various
interfaces on the Shield Board.

The
UART communication extension socket is not placed by default. When the socket is placed, it can
be used to directly plug an UART transceiver module of MikroElektronika like the ‘RS232 click’ or ‘RS485
