Sdmplayer: common questions

What microcontroller does the Sdmplayer use?

The Sdmplayer is built around the STM32F103RCTx, from the STM32 family.

How big is the Sdmplayer PCB?

The Sdmplayer measures 47.2 × 69.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sdmplayer?

72 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sdmplayer design files?

From the SL-RU/sdmplayer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Sdmplayer design in my own project?

Yes, under the terms of its MIT license, which SL-RU chose for the repository.

Can I test firmware for the Sdmplayer 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.
