Ssd1327: common questions

What microcontroller does the Ssd1327 use?

The Ssd1327 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Ssd1327 PCB?

The Ssd1327 measures 40 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ssd1327?

30 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ssd1327 design files?

From the Hong-Kong-Public-Transport/RC-Bus-System repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ssd1327 design in my own project?

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

Can I test firmware for the Ssd1327 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.
