Antennino is a wireless, low-power microcontroller board that is open-source, specifically designed for applications in the Internet of Things (IoT).
Antennino integrates 433 MHz radio communication with Arduino allowing compact solutions for remote data logging, sensing, and automation projects.
Key Features
Microcontroller: ATmega328P (PicoPower technology)
Radio Module: RFM69 transceiver with AES hardware encryption, operrating at 433 MHz
Memory: 512 Kbit Flash memory (AT25F512B) for data logging and OTA programming
Sensors: Onboard photoresistor for light detection and DS18B20 temperature sensor
Connectivity: Four Grove connectors for RS232, I²C, analog input and general-purpose I/O
Display Support: Small OLED display provision during gateway mode
Power Options:
1. Two AA batteries (alkaline 1.5V or rechargeable 1.2V)
2. External supply voltage from 3.6V to 12V
3. Direct 3.3V supply avoiding onboard regulators
Dimensions: 109mm x 50mm x 19mm
Low Power Consumption
Antennino is designed to operate in an energy efficient manner. It uses the TPL5110 timer from Texas Instruments which enables deep sleep mode while consuming 35nA standby power.
This feature enhances operational life significantly for battery powered applications.
Applications
Antennino’s design makes it appropriate for a wide range of applications:
Remote Sensing: Set up as a sensor node in the systems for tracking temperature and light.
Home Automation: Wireless control of devices or monitoring of devices’ states, i.e., door/window sensors.
Data Logging: Periodically accumulating data over time into a storage medium for analysis.
IoT Gateways: Act as an intermediary between the sensor networks and the internet, especially when an OLED display is added for status information monitoring.
Programming and Compatibility
Users can program Antennino using familiar tools as it is fully compatible with the Arduino IDE.
The RFM69 module onboard facilitates secure wireless communication, and the design of the board is meant for OTA updates which improves maintenance and deployment.
Conclusion
As a wireless project, Antennino is effective and energy saving and serves best with remote projects.
Its intergration of an Arduino board and a 433MHz radio module at an affordable price makes Antennino an important device for developers and hobbyist aiming at relaiable low powered devices.
