Features: BW16 is a double band WiFi Bluetooth-compatible SoC base on the RTL8720DN chip. It supports double band WiFi (2.4GHz or 5GHz) and Bluetooth-compatible Low Energy 5.0. The BW16 development board is a cores development board suitable for the BW16. The development board continues the classical design of the NodeMCU development board to the pin series on both side. In addition, seven color lights is integrated and developers can also connect peripherals as need. It integrates ARM (suitable for M4F) high-performances ARM V8M low-current MCUS, WLAN (802.11a/b/g), Bluetooth-compatible baseband and RF baseband and also offer configurable GPIO port. Perfect for lighting control, wearable health monitors, and industrial sensors networking, enabling real time data transmission and cloud platform integration.
