Tanmatsu hardware: common questions
What microcontroller does the Tanmatsu hardware use?
The Tanmatsu hardware is built around the ESP32-P4, from the ESP32 family.
How big is the Tanmatsu hardware PCB?
The Tanmatsu hardware measures 114.9 × 129.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Tanmatsu hardware?
320 components, from 85 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 Tanmatsu hardware design files?
From the Nicolai-Electronics/tanmatsu-hardware 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 Tanmatsu hardware design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which Nicolai-Electronics chose for the repository.
Can I test firmware for the Tanmatsu hardware without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
