8-bit MCU Development Board connects to 5G LTE-M Narrowband-IoT networks

Microchip has announced the AVR-IoT Cellular Mini Development Board based on the AVR128DB48 8-bit microcontroller (MCU), providing a platform to build sensor and actuator nodes on 5G narrowband IoT networks.

The Development Board’s small form factor makes it suitable for developers who want to connect IoT devices to an available 5G network. This is an essential feature for devices on the go or located in remote areas with limited availability of Long Range (LoRa) networks or other Low Power Wide Area Network (LPWAN) solutions.

Customers will have access to the flexibility and ease of design offered in the latest AVR128DB48 8-bit MCU family, including security protection with Microchip’s ATECC608 CryptoAuthentication device. The ATECC608 device can easily be configured to most major cloud service providers through Microchip’s IoT Provisioning Tool.

The AVR-IoT Cellular Mini Development Board comes pre-configured to send data from on-board light and temperature sensors to the cloud, viewable using Microchip’s sandbox portal. The sandbox portal provides customers with the ability to track and monitor their device in real time from a remote location.

This functionality covers the core requirements of many applications in various industries including agriculture, industrial and energy, as well as consumer spaces.

To provide an efficient and more cost-effective solution for developers to connect IoT devices to 5G using the AVR128DB48 MCU, Microchip has partnered with Sequans to include its Monarch 2 GM02S single-chip radio equipped with 5G LTE-M and narrowband IoT. Microchip also partnered with Truphone to provide the SIM card for cellular service that offers reliable coverage worldwide.

The AVR-IoT Cellular Mini Development Board fits the Adafruit Feather form factor and features a Qwiic/Stemma I2C connector for easy functionality extension, creating a clear path to production. It is also Arduino-compatible and is supported by Microchip’s Github Library which provides functionality for HTTPS, MQ Telemetry Transport (MQTT), and low power.
