Transponders

This project is accompanied by an open-source transponder project as well.

You can manufacture them at JLCPCB, a popular Chinese fabhouse. 5 panels (40 pcs tranponders) cost me $200, including taxes and shipping to EU (2026 May). The fabhouse produces the PCB and assembles with components - you have to program the ATTiny, solder the wires and deal with the mechanical protection.

Known sellers

Being an open source project, anyone can sell them. For a small amounts, ask around at rctech forum. If you need larger quantities, go to JLCPCB.

• Attila Zseller - zsellera@gmail.com - EU only, as untracked mail; assembled, pre-programmed panels. €30/panel + €5 shipping; 2 panels max.

If you have spares to sell, ping me or send a PR with your details. Most people want a single panel and aren't quite willing to place a $200 MOQ order, let alone learn how to program these embedded devices. Serving your community this way would give this project a great kickstart. Thanks!
