The first and second ports of FT4232H are used for remote debug of JTAG, Bootmode, ONOFF, SYS_nRST, and Power
Measurement Board communication. Developers can load different images on PC for associated applications.
The connector is as shown in
Figure 2 .
2.18 M.2 slot and Wi-Fi/Bluetooth module (J10)
One M.2/NGFF KEY-E slot (J10) is provided on the EVK board to support PCIE3.0, SDIO, I2S, UART, I2C, and GPIO connection.
This port can be used for Wi-Fi/Bluetooth card, NVMe PCIE SSD or 3G/4G cards. On the EVK board, Wi-Fi/Bluetooth module
Azurewave AW-CM276MA-07H (PCIE+UART) is assembled as default. It’s based on NXP 88W8997 chipset, supports Wi-Fi 5
(802.11ac) 2 × 2 Dual-Band (2.4/5 GHz), Bluetooth 5.1.
The connector is as shown in
Figure 2 .
2.19 Expansion connector (J21)
One 40-pin dual-row Pin Header connector (J21) is provided on the EVK board to support I2S, UART, I2C, and GPIO connections.
Developers can use the header for access to various pins or to plug in accessory cards like the 8MIC-RPI-MX8.
The connector is as shown in
Figure 2 .
