Power distribution and monitoring

Smart Power Protection: This homebrew powerboard actively monitors input voltage to safeguard connected RTB modules. It automatically interrupts power to the RTB subsystem if the voltage drifts outside the safe range of 12V to 18V, preventing damage from erroneous power conditions.

RTB C11: common questions

What microcontroller does the RTB C11 use?

The RTB C11 is built around the AVR64DA48, from the AVR/Arduino family.

How big is the RTB C11 PCB?

The RTB C11 measures 160.3 × 71.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RTB C11?

112 components, from 42 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 RTB C11 design files?

From the git4dcc/RTB_C11 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 RTB C11 design in my own project?

Yes, under the terms of its Apache-2.0 license, which git4dcc chose for the repository.

Can I test firmware for the RTB C11 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
