REQUEST PRODUCTFW & SW TOOLS
Meteca offers a complete firmware solution for SAMD21 present on the board, written in C/C++ and fully compatible with Arduino for a fast and simple prototyping process.
The MBC-CEL is programmable using the Arduino IDE or a more professional IDE like Visual Studio Code. The latter, in particular, allows customers to program and debug the SAMD21 using different programming languages and/or SDK like Microchip’s ASF or python, using several debugging devices like ATMEL ICE (link) and/or Segger J-Link (link).
The software suite offered includes a set of tools specifically designed to allow firmware update procedure (via USB for both the MCUs).
FREQUENTLY ASKED QUESTIONS
FAQ
How the LTE module and the MCU communicate?
The LTE module exposes two UART interfaces one for the LTE function and one for the GNSS function. These two serial interfaces are routed both to the companion MCU and to the module pinout. This allows the module to be controlled via its embedded MCU or by an external device.
What are the operational voltage levels for the module?
Depending on the MBC model chosen and the technology it embeds, the operating voltages may vary considerably.
Always read the instructions carefully, which is available in the module’s documentation you want to use. The MBC-CEL module requires two different power supply, one for the SAMD21 (3.3V with 100mA current capability)
and one for the LTE/GNSS chip (3.8V with at least 2A of peak current capability).
How much is the power consumption?
Depending on the MBC model chosen and the technology it embeds, power consumption may vary considerably.
The maximum current draw is up to 2A for small burst – shorter than 1ms – while during normal activity it ranges from
900mA, down to a couple of mA
Which is the communication protocol used to control the LTE and the GNSS functionality?
The AT7672 chip features an AT command based UART interface for the LTE part of the chip and a NMEA based UART interface for the GNSS part. For the complete set of commands available, please refers to the supplied documentation.
