1. Product Description
This Wi-Fi BT IOT add-on card is a network connectivity module that can be
plugged into an IOT host. The edge connector pinouts are as per IOT card
specifications i.e., a total of 38 pin gold fingers with each side having 19 pins as
per standard signal pinouts for IOT host interfacing.
This module is built on Qualcomm’s QCA9377-3 which is a single-die wireless
local area network (WLAN) and Bluetooth (BT) combination solution to support 1
× 1 IEEE 802.11a/b/g/n/ac WLAN standards and BT 4.2 + HS, enabling seamless
integration of WLAN/BT and low energy technology. The design supports a low-
power SDIO 3.0 interface for WLAN and a UART/PCM interface for BT.
A RP-SMA connector is provided for connecting antenna for WIFI and BT
operations. A 48MHz crystal is connected to QCA9377 for clock generation. The
QCA9377 has inbuilt PA/LNA for 2.4GHz and external PA/LNA for 5GHz.The card
works with 3.3V (core power) and 1.8V (IO power) received from the IOT gateway.
There is an on-board 3.3V regulator to make sure the power source is clean and
stable to QCA9377.
