TART3 Motherboard: common questions
What microcontroller does the TART3 Motherboard use?
The TART3 Motherboard is built around the K7805MT-1000R4, from the RISC-V family.
How big is the TART3 Motherboard PCB?
The TART3 Motherboard measures 199.4 × 169 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the TART3 Motherboard?
89 components, from 54 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 TART3 Motherboard 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 TART3 Motherboard 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 TART3 Motherboard 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.
