LocketRadioSnd: common questions

What microcontroller does the LocketRadioSnd use?

The LocketRadioSnd is built around the STM32L476RCT6, from the STM32 family.

How big is the LocketRadioSnd PCB?

The LocketRadioSnd measures 30 × 103 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LocketRadioSnd?

115 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the LocketRadioSnd design files?

From the Kreyl/LocketRadioSnd repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LocketRadioSnd design in my own project?

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

Can I test firmware for the LocketRadioSnd 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.
