This product consists of two stacked boards. The base board is built around an ESP32-S3-WROOM-1-N8R8 module featuring Bluetooth, Wi-Fi, and an integrated CAN transceiver. It includes an onboard RGB LED, boot and reset buttons, and is programmed via a USB-C interface.
The top board is designed for NMEA 2000 device simulation and features two potentiometers, two push buttons, and four indicator LEDs. By default, the device simulates temperature data on PGN 130316, adjustable via potentiometer P1, and humidity data on PGN 130313, adjustable via potentiometer P2. All simulation functions, including PGN assignments and control behavior, can be reprogrammed through firmware to support custom applications.

Simulation
PGN 130316 is used to simulate temperature data on the NMEA 2000 network. In the default firmware configuration, temperature values are generated by the device and adjusted in real time using potentiometer P1 on the top board. This allows controlled variation of the transmitted temperature parameter for testing and demonstration purposes. The associated behavior, scaling, and update rate can be modified through firmware reprogramming to support alternative temperature-related simulations or custom PGN payloads.
PGN 130313 is used to simulate humidity data on the NMEA 2000 network. In the default configuration, humidity values are adjusted using potentiometer P2, enabling precise manual control of the transmitted data. As with the temperature simulation, the firmware is fully reprogrammable, allowing PGN 130313 to be repurposed, reassigned, or replaced with other environmental or sensor-related PGNs as required by the application.
