Gpio Jumpers; Header Pin-Out - Ublox EVK-BMD-340 User Manual

2.10 GPIO jumpers

Many solder bridge jumpers on the board are available to allow GPIO configuration. Most solder
jumpers are used to remove on-board components from the module's GPIO nets to eliminate
interference with external circuitry added on the I/O headers. All GPIOs are directly connected
to the I/O Headers by default, except P0.00 & P0.01 (32 kHz crystal), P0.09 & P0.10 (NFC
antenna), and P0.17 & P0.20 - P0.23 (QSPI). These are disconnected from the I/O headers as
they would interfere with the default functions. The GPIO jumpers are shown on the bottom of
the BMD-34 evaluation kit.

2.11 Header pin-out

Headers J5 - J9 and J11 break out the IO signals from the BMD-34 module on 2.54 mm pitch
headers.

⚠
The I/O pins of the BMD-34 EVK are not 5 V tolerant. Arduino Uno® style shields shall be
configured to use +3.3 V DC (VSHLD) as the I/O voltage reference.
The tables below are presented in order of the headers on the BMD-34-eval boards.
