Product Descriptions
The BW15 Kit development board is a core development board based on the BW15 module for 2.4GHz WiFi and Bluetooth BLE4.2. This development board continues the classic design of NodeMCU development board, leading all I/O to the pin headers on both sides. Developers can connect peripherals according to their own needs.
The BW15 Kit development board comes with RGB light beads, which can save a lot of time for smart light control developers in the early stages of development and quickly verify product feasibility.
The BW15 Kit and new modules integrate internal memory, supporting simple application development. CH340 serial chip is used to support serial communication and basic AT instruction development.
