NICEMCU BW16 development board is a core development board designed for the BW16 module. The board features a classic NodeMCU-style layout, with all I/O pins brought out to rows on both sides. It includes an onboard RGB LED. Developers can connect peripherals as needed. The BW16 is a dual-band Wi-Fi and Bluetooth SoC module based on the RTL8720DN chip. It supports dual-band (2.4 GHz and 5 GHz) WLAN and Bluetooth Low Energy 5.0. It integrates an ARMv8-compatible high-performance MCU (Cortex-M4F), an ARMv8-M-compatible low-power MCU (Cortex-M0), WLAN (802.11a/b/g/n), MAC, Bluetooth baseband and RF, and a set of configurable GPIO ports for peripheral control.
