From prototype to product in a simple and fast way
Full code control for both the chips thanks to the exposed debug interfaces
Small form factor with a big amount of GPIOs and peripherals
Fluid logic to surpass the classical rigid master/slave topology
Embedded security thanks to the dedicated cryptochip
Software-selectable flexible power modes
Software-selectable radio band (868MHz, 915MHz or 433MHz)
Meteca offers a comprehensive firmware for both the MCU on the MBC-LR module, written in C/C++ and fully compatible with Arduino for a fast and simple prototyping process.
All Briki MBCs are completely programmable using Arduino IDE or the more professional Visual Studio Code with PlatformIO plugin. The compatibility and the support with the latter one, allows customers to program both the MCUs using different programming languages and/or SDK like Microchip’s ASF or python.
Both the MCUs have their debugging interface exposed on the module’s pinout to ensure a full control over the firmware implementation. In conjunction with Visual Studio Code, several debugging interfaces can be used to extensively debug the code (like Atmel ICE or Segger J-Link that are useful for both the MCUs).
Beside all of this, the software suite offered includes a set of tools specifically designed to allow firmware update procedure (via USB for both the MCU), as long as automatic pin-mapping configuration.
