Baseboard: common questions
What microcontroller does the Baseboard use?
The Baseboard is built around the K7805MT-1000R4, from the RISC-V family.
How big is the Baseboard PCB?
The Baseboard measures 100 × 71 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Baseboard?
40 components, from 30 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 Baseboard design files?
From the tart-telescope/radio_module 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 Baseboard design in my own project?
Yes, under the terms of its GPL-3.0 license, which tart-telescope chose for the repository.
Can I test firmware for the Baseboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
