■
Circuit to measure/monitor the current from LDO to VBAT
□
Software trigger support for SmartSnippets Toolbox (driven from a DA1469x GPIO, P0_16,
through a jumper)
■
DIP switch to isolate UART and JTAG signals (in case we need to secure the most accurate
sleep current measurements,
Figure 4
)
□
The board is shipped with all switches at the
“ON” position (all signals connected to the
related DA1469x pins)
□
Signal names are marked on PCB top silkscreen

■
Test points (TP) for automated production test (placed on the bottom of the board)
■
Ground points (TP28 and TP29) for connecting crocodile clips
■
QSPI-RAM option (not populated)
■
Optional Arduino sockets (supporting 3.3 V compatible Arduino shields)
