[Introduction]：E220-400MBL-02-The MBL series evaluation kits are designed to help users quickly evaluate EBYTE's next-generation package-compatible wireless modules. Most of the pins on the board are led out to the pin headers on both sides, making it easy for developers to connect a variety of peripherals via jumpers to their need.
