This connects V
Note
SDIO clock speeds higher than 50 MHz can only be achieved with
a SDIO signal voltage level (V
that supports the SDIO 3.0 Standard.
The maximum achievable data rate is limited by the used SDIO
clock speed.
For further information please refer to the module product
specification
IO Reference Voltage
In case your host processor board supports only IO voltage levels of 3.3 V you can
reconfigure the PAN9028 M.2 device to use 3.3 V as voltage level for its UART and
IOs.
The voltage used by the IOs and the UART interface is determined by the voltage
applied to V
. You can configure it to either 1.8 V or 3.3 V.
