Dual board carrier: common questions

What microcontroller does the Dual board carrier use?

The Dual board carrier is built around the STM32F042K6TX, from the STM32 family.

How big is the Dual board carrier?

The Dual board carrier measures 63 × 36.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dual board carrier?

26 components, from 19 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 Dual board carrier design files?

From the jlwinland/wideband repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dual board carrier design in my own project?

Yes, under the terms of its Unlicense license, which jlwinland chose for the repository.

Can I test firmware for the Dual board carrier 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.
