!Application Icon for Serial Studio Serial Studio






Serial Studio turns data from your hardware into a live dashboard.

Connect an Arduino, ESP32, STM32, Raspberry Pi, Teensy, or anything else that speaks serial, Bluetooth, a network protocol, or an industrial bus. Describe the data format once in a project file. Serial Studio draws the plots, gauges, maps, and 3D views around it. Send commands back with buttons, sliders, and knobs. Record a session, replay it, export it as a PDF.

It replaces the stack of separate tools this work usually requires: a serial monitor and serial plotter for Arduino and ESP32 development, a real-time telemetry dashboard, a data logger that records to CSV or SQLite, and a PLC, Modbus, CAN bus, OPC UA, or MQTT monitor for industrial and IoT systems.

Runs on Windows, macOS, Linux, and Raspberry Pi.

!Software usage

Use cases shows how people apply it across 18 fields, from rocketry and drones to industrial automation. Comparison sets it against the Arduino IDE Serial Plotter, Processing, MATLAB, LabVIEW, and Grafana.

 What you can do with it

Connect to a device. Serial/UART, Bluetooth LE, and network sockets (TCP, UDP, WebSocket, HTTP) in the GPL build. MQTT, Modbus TCP/RTU, CAN Bus, OPC UA, Siemens S7comm, EtherNet/IP, IEC 60870-5-104, audio input, raw USB (libusb), HID (hidapi), and Process I/O are Pro. Multiple devices in one project is also Pro.

Read PLCs without a gateway (Pro). OPC UA covers modern controllers: browse the address space, tick the tags you want, and the project generates itself. Three direct drivers cover the rest of the plant floor, no KEPServer-class gateway in between. S7comm polls absolute addresses (DB5.DBD20:REAL, MW10) on Siemens S7-300, S7-400, S7-1200, and S7-1500 controllers. EtherNet/IP polls symbolic tag names on Allen-Bradley ControlLogix, CompactLogix, MicroLogix, Micro800, SLC 500, and PLC-5, plus Omron NJ/NX. IEC 60870-5-104 interrogates RTUs and substation gateways and streams their spontaneous reports, generating the project from the station's own database. All three are read-only clients: connecting Serial Studio to a running machine cannot change its state. On the MQTT side, Sparkplug B works in both directions — subscribe as a host application and generate a project from the birth certificates, or publish your dashboard as an edge node.

Visualize data. 17 widgets in the GPL build: line plots, gauges, bar charts, meters, GPS maps, FFT spectrum, accelerometer, gyroscope, compass, data grids, LED panels, terminal, multi-channel plots, web view, bar panel, plus a Clock and Stopwatch utility widget pair. Bar, Gauge, Compass, and Meter each render as a two-page swipe view (page 0 is the analog face, page 1 is a large digital readout), so a single tile shows both the trend at a glance and the exact value. Pro adds 3D Plot, Waterfall (spectrogram), Image View (live camera), the Canvas widget, and output widgets (buttons, sliders, knobs, an Output Panel, and a Notification Log)
