Ti92revive: common questions

What microcontroller does the Ti92revive use?

The Ti92revive is built around the TCA8418, from the ESP32 family.

How big is the Ti92revive PCB?

The Ti92revive measures 205 × 113.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ti92revive?

88 components, from 83 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ti92revive design files?

From the ccadic/TI92-revive repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ti92revive design in my own project?

The repository has no license, so all rights stay with ccadic. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ti92revive 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.
