By type, the board carries 13 connectors, 12 ICs, 12 resistors, 6 capacitors, 2 transistors and 2 switches.

It belongs with the power & battery designs in this gallery.

From the project

Custom PCB replacing the upstream NovaSM3 v5.2b. Driven by the v3.2 architecture audit: - XL4016 buck rails undersized for walking-gait current (8A cont. vs measured 8-12A avg + 25-40A impact transients) - No safety chain (no LVC, no E-stop, no per-rail telemetry, no fuse spec) -

Nova pcb v6: common questions

What microcontroller does the Nova pcb v6 use?

The Nova pcb v6 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Nova pcb v6?

The Nova pcb v6 measures 112 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Nova pcb v6?

51 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nova pcb v6 design files?

From the Ace2932/Fennec repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nova pcb v6 design in my own project?

Yes, under the terms of its MIT license, which Ace2932 chose for the repository.

Can I test firmware for the Nova pcb v6 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.
