PCBWay sponsors full-size SD module for Arduino projects — author keeps independence, for now

The pitch, and the moral knot

It has been reported that PCBWay emailed the creator of the BurgerDisk project offering up to $100 in free PCB manufacturing in exchange for a review. The author says they usually refuse paid sponsorships to protect editorial independence — and you can feel the tug of principle. But PCBWay allegedly allowed the author full freedom to write whatever they wanted, so the deal went ahead: a sponsored build of a full‑size SD card module intended as a proper Arduino‑friendly option.

Why this module matters

Why bother? Because most cheap full‑size SD modules on AliExpress lack the proper level shifting for MOSI/MISO/CS/SCLK lines and are dangerous for 3.3V SD cards when paired with 5V microcontrollers like classic Arduinos. So the new board includes level shifters and a proper regulator. The author cites specific parts used in the design — a SE5218ALG regulator, a TXB0104PWR level shifter and an SD‑106M card holder — and argues the result will be more robust than the generic $1 clones.

PCBWay vs JLC: tradeoffs and workflow

The writeup doubles as a mini comparison. PCBWay gets praise for being cheap (the author recalls about $12 shipped for five two‑layer PCBs in early prototyping) and for sweeteners like Kicad support: upload a KiCad design and PCBWay returns 10% of the order to the KiCad project — a neat nudge toward supporting free software. They also offer a “Share & Sell” route so open designs can be ordered directly from PCBWay. By contrast, the author switched to JLCPCB for assembled SMD work, liking JLC’s BOM interactivity and LCSC integration — though they warn JLC’s fast human DFM checks have allegedly missed fairly serious layout problems, like an unfilled ground plane.

What to expect

Ordering through PCBWay is reportedly slower because staff pick components from your BOM values rather than an automated parts picker, but that extra time helped the author spot issues before finalizing the order. The finished module will be listed in PCBWay’s Share & Sell catalogue, making it easy — if a bit pricier than AliExpress mass-produced parts — for makers to buy a ready‑assembled, Arduino‑safe full‑size SD module. It’s a small moment, but one that underlines two trends: makers demanding better, safer modules, and manufacturers nudging open‑source tooling with real dollars.
