RK3288 Hardware Design Guide
23 WIFI & BT
23.1 Schematic
RK3288 supports WIFI/BT module with SDIO 3.0. If WIFI/BT module with SDIO, UART is
used, power supply APIO3_VDD of SDIO, UART controller must keep the same with VIO
module, as shown in Fig 23-1, 23-2.
Tips
：
On the circumstance of SDIO 3.0
，
APIO3_VDD power supply must be 1.8V
；
Fig 23-1
Fig 23-2
WIFI RTC_CLOCK should be matched with equal voltage level and select suitable resistor
to share partial voltage, to meet WiFi input demand, otherwise, it will cause abnormal working
of WiFi, as shown in Fig 23-3, 23-4.
