Pangotag: common questions

What microcontroller does the Pangotag use?

The Pangotag is built around the MAX-M10S, from the STM32 family.

How big is the Pangotag PCB?

The Pangotag measures 23 × 18 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pangotag?

90 components, from 53 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 design files?

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

Can I use the Pangotag 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 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.
