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.

It features:

− One ATSAMD21G18A ARM® Cortex®-M0+ MCU - best for control purposes (like motor and actuator control, sensor

acquisition, SERCOM interface etc.);

− one ESP32-D0WD dual-core Tensilica Xtensa LX6 running @ 240MHz with integrated Wi-Fi and dual-mode

Bluetooth, perfect for connectivity and heavy computational tasks;

− One CryptoAuth ECC608A chip - for securing cloud connections and the OTA/boot procedure;

− One QSPI 64-Mbit or 128-Mbit flash - for storing both ESP32 firmware and user data.

Both the MCU’s are fully user accessible (both in programming and debugging) to allow a perfect

configuration/customization for each design. This feature gives the user the power to decide which of the two MCUs

should act as a master or a slave (or have a more “liquid” configuration) and what features each chip should

implement in order to achieve a perfect balance between power consumption, functionalities implemented and

overall performance.

The two MCUs share two high-speed communication interfaces (plus some synchronizing signals): one SPI and one

UART suitable for data exchange and firmware update.

Each chip has the capability of its own auto-update - or counterpart's firmware, allowing both in-board (through serial

or USB interfaces) and over-the-air (through Wi-Fi or BT interfaces) firmware upgrade mechanisms in a secured

environment thanks to the CyptoAuth chip supplied with the board.

Every MBC features a specific ID line that allows a carrier board to recognize the SoM characteristics (MCUs

mounted on the SoM, operating voltages, power consumptions, features enabled, etc.)
