Pangotag PCB LCSC compat2: common questions

What microcontroller does the Pangotag PCB LCSC compat2 use?

The Pangotag PCB LCSC compat2 is built around the STM32U575RGTx, from the STM32 family.

How big is the Pangotag PCB LCSC compat2?

The Pangotag PCB LCSC compat2 measures 31.9 × 27.2 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Pangotag PCB LCSC compat2?

91 components, from 54 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pangotag PCB LCSC compat2 design files?

From the andrewo3/pangotag-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pangotag PCB LCSC compat2 design in my own project?

The repository has no license, so all rights stay with andrewo3. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pangotag PCB LCSC compat2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
