Ohmeris and EasyEDA
EasyEDA is a free PCB suite tied closely to JLCPCB and LCSC, so ordering boards and parts is one click. Ohmeris focuses on testing the circuit first: instruments and firmware on your schematic.
EasyEDA facts checked 2026-10-24 from the linked public sources. Tell us if something has changed.
Where EasyEDA is better
- Free for commercial use, with paid plans only for storage and no ads
- One-click board ordering at JLCPCB and parts at LCSC
- Mature PCB tools and a very large parts library with 3D models
- Imports from many professional tools
- Desktop apps as well as the browser
Where Ohmeris is different
- Microcontroller firmware running on your schematic
- Scope, logic analyser and bus decoders on the live circuit
- Built-in AI with a clear list of every change
- KiCad export and an open JSON copy of every project
Side by side
| Area | EasyEDA | Ohmeris |
|---|---|---|
| Price | All features free, commercial use allowed; free plan shows ads and has 0.5 GB storage. Individuals $19.9/month (billed yearly). [pricing] | Basic $9, Pro $19 or Premier $49 a month, no ads. |
| Where it runs | Browser, plus desktop apps for Windows, Linux and macOS. [download] | In the browser; nothing to install. |
| Simulation | Pro: SimulIDE (real-time) and ngspice (transient, AC), analog and digital. Standard: operating point, DC, AC and transient. [Pro docs] | Transient, AC (Bode), DC sweep and operating point. |
| Firmware on the circuit | Pro's simulator states it is not applicable to microcontrollers. [Pro docs] | AVR, PIC16 and a supported RP2040 path run against your schematic. |
| Instruments | Voltage probes and waveform cursors; scope, logic analyser and bus decoders not documented. [FAQ] | Oscilloscope, multimeters, logic analyser and I²C/SPI/UART decoders. |
| PCB | Standard documents 34 copper layers. Pro: push routing, differential pairs, equal-length tuning, autorouter, custom DRC. [routing] | 2 or 4 layers, push-and-shove, length matching, auto-route, DRC. |
| Import | Pro: Altium, Allegro/OrCAD, DipTrace, Eagle, KiCad (before 10.0), LTspice, PADS, Protel, Pulsonix, EasyEDA Standard. [import] | KiCad PCB, EasyEDA Standard and Eagle schematics. |
| Export | Pro: Gerber, ODB++, IPC-D-356A, BOM, pick-and-place, Altium, PADS, 3D. KiCad export not documented. [export] | KiCad PCB, Gerber, ODB++, IPC-356, pick-and-place, open JSON. |
| Parts and ordering | Order parts at LCSC and boards at JLCPCB from the editor; JLCPCB assembly part selection built in. [easyeda.com] | Part search with sample prices; no built-in ordering. |
| Teamwork | Project members and teams with roles; real-time simultaneous editing not documented. [collaboration] | Real-time shared editing and saved revisions you can replay exactly. |
| AI | A built-in assistant is not documented; an official open-source skill lets an external coding agent (such as Claude Code or Codex) drive EasyEDA Pro. [JLCPCB blog] | Built-in AI drafts and edits schematics; every edit lists what changed. |
Which one should you pick?
Pick EasyEDA if you want a free tool and plan to order boards and parts from JLCPCB and LCSC. Pick Ohmeris to test your circuit and firmware on a virtual bench before you order, with files you can take to any fab or tool.
