• Revision 2.0 module of LS9AD, HOST MCU communication is on pin 43(Tx)
and 45(Rx); pin 49(Tx) and 51(Rx).
For LS9AD-AC11DBT-GV Modules
• Pin J1.8  I2S_MCLK will be configured as PDM_CLK when Google voice
assistant image is updated.
o There will be no MCLK output and this pin must be connected to
PDM MEMS MIC.
• Pin J1.20  I2S_RXD will be configured ass PDM_DAT when Google voice
assistant image is updated.
o There will be no AUX input and this pin must be connected to PDM
MEMS MIC.
