A removable jumper (on J7 and J9) is provided to break the power supply line directly to the module, allowing you to measure
current consumption. For normal operation, the jumper on J7 (and J9) must be fitted (and is fitted by default).
IMPORTANT:
To achieve the optimal power consumption of the BL654PA series module on the development board, see
the “
lp.low.power.deep.sleep.sb
” file in the GitHub
smart
BASIC sample application repository on the
BL654PA product page at
https://github.com/LairdCP/BL654PA-Applications
Note:
This measures the current consumption of the
BL654PA
series module ONLY.
The current drawn by the BL654PA series module can be monitored on the development board.
