Important Boundary
This is a Rev A1 JLC-oriented CAD baseline for review. It is not a fabrication release until the pin-by-pin schematic, routing, footprint models, JLC BOM matching, and DFM are reviewed.
Manufacturing Direction
- 4-layer PCB.
- Double-sided SMT assembly.
- No assumed user hand-soldering.
- Pogo/test pads replace the visible SWD header direction.
- Front side is kept mostly optical; back side carries logic, USB, power, and service controls.
Visual Mapping
- D1 and D2: left long bar, oldest side.
- D3: left middle short bar.
- D4: right middle short bar.
- D5 and D6: right long bar, newest side.

Questions
How big is the Tellmelight rev a1 PCB?
It measures 96 × 74 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tellmelight rev a1 use?
52 parts, built around the RP2040, W25Q32JVSSIQ, AP2112K-3.3 and TPD2EUSB30DRT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Tellmelight rev a1 KiCad files?
From the qiaoyo/TellMeLight repository on GitHub, at the commit this page was made from: the board is hardware/kicad/tellmelight_rev_a1/tellmelight_rev_a1.kicad_pcb and its schematic hardware/kicad/tellmelight_rev_a/tellmelight_rev_a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tellmelight rev a1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask qiaoyo before reusing the design.
