A familiar controller on a custom board
Baztech’s custom board-design work includes a project using the ATmega328P microcontroller from Microchip, formerly Atmel. This is the classic controller associated with the Arduino Uno. The project puts this controller into a custom board design for communication between nodes within a building.
An RFM95W LoRa radio module provides the wireless link. The application uses LoRa point-to-point (P2P) communication to transmit data between the boards and other nodes in the installation.
Node-to-node communication for a building application
The integration combines custom PCB design, controller firmware and the radio link around the project’s data-transmission requirements. The ATmega328P provides the controller layer, while the RFM95W handles the LoRa radio layer.
The supplied photos show multiple custom boards with powered displays, including a close-up of a network-test screen displaying RSSI. They document the board-development setup without specifying a measured communication range or building-wide coverage result.
Planning a similar custom node in Malaysia
For a new enquiry, share the data to transmit, intended node locations, number of nodes, power arrangement and reporting interval. The building layout and installation conditions help define the communication-test scope alongside the electronics and firmware requirements.
Baztech can discuss a custom board and node-communication setup around these requirements.
Questions about this integration
Which controller and radio are used?
The project uses an ATmega328P microcontroller with an RFM95W LoRa module on a custom board design.
Does this project use LoRaWAN?
The supplied project uses LoRa P2P communication between nodes. It is described separately from our LoRaWAN gateway and sensor integrations.
What is the intended application?
The boards transmit data to other nodes within a building. The payload and node arrangement are defined around the project’s requirements.
