Zxevo.pentevo: common questions
What microcontroller does the Zxevo.pentevo use?
The Zxevo.pentevo is built around the TQFP64X8, from the RISC-V family.
How big is the Zxevo.pentevo PCB?
The Zxevo.pentevo measures 173 × 171 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Zxevo.pentevo?
338 components, from 72 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 Zxevo.pentevo design files?
From the aaydev/zxevo.pentevo 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 Zxevo.pentevo design in my own project?
The repository has no license, so all rights stay with aaydev. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Zxevo.pentevo 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.
