TekTag BioSensor: common questions

What microcontroller does the TekTag BioSensor use?

The TekTag BioSensor is built around the STM32WB55VGY6TR - Seq, from the STM32 family.

How big is the TekTag BioSensor PCB?

The TekTag BioSensor measures 26 × 25 mm, has 6 copper layers and is 1 mm thick.

How many components are on the TekTag BioSensor?

77 components, from 48 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 TekTag BioSensor design files?

From the teklabsdigital/TekTag 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 TekTag BioSensor design in my own project?

Yes, under the terms of its MIT license, which teklabsdigital chose for the repository.

Can I test firmware for the TekTag BioSensor 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.
