2.2.2 WIFI & BT Function Circuit
The WIFI & BT module supports Wi-Fi IEEE 802.11 b/g/n/ac, Bluetooth 5.0 with BLE. And it’s required that the
impedance of the antenna path is 50 Ω to maximize the power of the antenna.
Figure 2-2 Halley5 Core Board WI-FI & BT Circuit
2.2.3 SPI Flash Function Circuit
The storage component on the Halley5 core board is 256MBytes SPI NAND Flash. And the hardware circuit
and PCB layout are compatible with both SPI NOR flash.
