NICEMCU BW16 development board is a core development board designed for BW16 module, the development board continues the classic design of NodeMCU development board, leading to all 1/O to of pins on both sides, on-board RGB seven color lights, developers can also connect peripherals according to their own needs. BW16 is a dual-band Wi-Fi+ Bluetooth SoC module based on RTL8720DN chip. It supports dual-band (2.4GHz or 5GHz)WLAN and Bluetooth Low Energy 5.0. It integrates ARM V8(compatible with for -M4F) high-performance MCUS, ARM V8M(compatible with for -MO) low-power MCUS, WLAN(802.11a/b/g), , Bluetooth baseband and baseband, and also provides a set of configurable GPIO ports. For the control of different peripheral devices.
