MBC – WB01 Product Specifications 3. Introduction The MBC-WB01 SoM is part of Meteca’s MBC family of devices. It follows the MBC standard specification that allows users to switch from one module to another (also with different MCU and/or functionalities) in a seamless fashion, since all modules share same pinout and dimensions. This compact and certified SoM is the ideal solution for designers that want a unique device with Wi-Fi & BT/BLE connectivity plus a dedicated control MCU.
