. In addition, connection to the character LCD header, EZ-BLE I/Os,
and Energy Harvesting PMIC outputs are available on the headers marked 20, 27, and 26 in
. Note that the connection to the character LCD header can be taken from the
odd pins on header J20. The CapSense pins on the shield can be used as general-purpose pins to
connect to the EZ-BLE I/Os and character LCD pins when CapSense is not used.

Known Limitations after Board Separation
The separated boards have some known limitations:
■
When the separated shield board is connected back to the main board through J26 or J27, the
EZ-BLE programming lines are not restored. As a workaround, use the EZ-BLE programming
header (marked 25 in
) to program the EZ-BLE device (if populated) on the
shield board.
■
In REV05 version of the PSoC 4 L-Series Pioneer board, when the shield board is used as an
Arduino shield or connected back to the main board after separation, V5.0 and V3.3 power
domains (from the main board) do not connect to the respective power domains of the shield
board. As a workaround, connect pin 8 and pin 10 on header J17 to the right pad of R44 and left
pad of R45 respectively, using jumper wires to enable V5.0 and V3.3.
shows this.
Note that this connection will bypass the onboard protection diodes, and any external voltage
larger than 3.3 V and 5 V on the respective domains will damage the active components
connected on this domain.
