TSAL G V4 2: common questions
What microcontroller does the TSAL G V4 2 use?
The TSAL G V4 2 is built around the ESP32-S3-WROOM-2, from the ESP32 family.
How big is the TSAL G V4 2 PCB?
The TSAL G V4 2 measures 140 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TSAL G V4 2?
117 components, from 60 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 TSAL G V4 2 design files?
From the HKUST-Red-Bird-Racing-EVRT/GEN5_ELEC 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 TSAL G V4 2 design in my own project?
The repository has no license, so all rights stay with HKUST-Red-Bird-Racing-EVRT. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the TSAL G V4 2 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.
