The NICEMCU BW16 development board is a core development board designed for the BW16 module. This development board continues the classic design of the NodeMCU development board, featuring pin headers from all 1/O to both sides, onboard RGB rainbow lights, and developers can also connect peripherals according to their own needs. BW16 is a dual band Wi Fi+Bluetooth SoC module developed based on the RTL8720DN chip. It supports dual band (2.4GHz or 5GHz) WLAN and low-power Bluetooth 5.0; And it integrates ARM V8 (compatible with Cortex-M4F) high-performance MCU, ARM V8M (compatible with Cortex-MO) low-power MCU, WLAN (802.11a/b/g/n), MAC, Bluetooth baseband, and RF baseband. It also provides a set of configurable GPIO ports for controlling different peripheral devices.
