PCB Composer

Combine our checked KiCad design blocks into your board. We compose the schematic, place and route the board, check it and deliver manufacturing files — from €99 for a Maker board to System boards with 25 blocks.

Board outline (optional)

Must the board fit a given space? Attach the outline it has to fit in: a DXF, the enclosure drawing (PDF, DWG, STEP) or a photo of a dimensioned sketch. Mark the fixing holes, connector positions and height limits if you know them. Up to 10 MB.

Free, no obligation: no payment, no deposit and no account. We store your request to answer it. The device descriptions are also kept as the training and test set for an AI tile picker we are building, which will later propose the tiles from such a description. We read the source of your visit (utm and gclid) from the page address; no cookies. A board outline you attach is stored on our own server with the request and used only to design your board. See the Privacy Policy.

How it works

Pick blocks or describe

Choose blocks for an instant price, or describe the device and we map it to blocks and quote.

Pay and review

Basic, Pro and System orders are reviewed by an engineer after payment. Maker boards go straight to the composer.

Compose and route

Our composer places the blocks (their layouts stay untouched), routes the connections and runs ERC, DRC and rule checks.

Get your files

Download the files on your order page, or have assembled boards made at JLCPCB.

  • Delivery times count from when we accept the order after payment.
  • More extra parts than a tier includes: the order moves to the next tier (above System: quote).
  • Maker: the €99 counts toward Basic if you later want an engineer review.
  • Boards are made and paid for at JLCPCB, separately from our price. Basic, Pro and System: upload our production package on jlcpcb.com (PCB + assembly). Maker: bare PCBs with the Gerbers.

How blocks are counted

Each different block counts as 1, each repeated copy as ½; the total is rounded up.

ESP32 core + buck + MPPT charger + 4 × low-side switch3 + 1 + 3 × ½ = 5.5 → 6Basic
