The devices directory contains schematics, PCBs & firmware for the client devices.

Inferno Embedded commands allow the device to be rebooted into the bootloader so that they can be updated. The device can also be forced to remain in bootloader mode by shorting SWDAT on the SWD header to GND with a jumper.

1Wire-LEDController: common questions

What microcontroller does the 1Wire-LEDController use?

The 1Wire-LEDController is built around the STM32F030R8, from the STM32 family.

How big is the 1Wire-LEDController PCB?

The 1Wire-LEDController measures 99.8 × 99.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 1Wire-LEDController?

35 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the 1Wire-LEDController design files?

From the InfernoEmbedded/onewire-softdevice repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 1Wire-LEDController design in my own project?

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

Can I test firmware for the 1Wire-LEDController 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.
