About the Min ssh serial bridge PCB

Min ssh serial bridge is an open source ESP32 PCB design by hnz1102, published on GitHub. It is a 2-layer board measuring 32 × 45 mm, with 20 components from 16 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the SSD1306_DISPLAY and AZ1117-CH3.3TRG1. By type, the board carries 7 resistors, 4 capacitors, 3 ICs, 2 connectors, 2 diodes and 1 switch.

It belongs with the iot & wireless designs in this gallery.

From the project

Firmware for the ESP32-S3 that bridges an SSH connection (over Wi-Fi) to UART and USB CDC serial ports. Written in Rust (esp-idf-hal / esp-idf-svc) with a C component (wolfSSH) for the SSH server.

- Fixed the OTA update completion message so it is displayed to the SSH client. - Fixed the Web UI terminal freezing while a serial target is booting. - Improved setup script compatibility across Linux distributions and made Xtensa toolchain setup more robust. - Split large USB CDC writes into multiple bulk transfers. - Fixed device reboot failures. - Fixed the custom partition table path used by…

Min ssh serial bridge: common questions

What microcontroller does the Min ssh serial bridge use?

The Min ssh serial bridge is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Min ssh serial bridge PCB?

The Min ssh serial bridge measures 32 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Min ssh serial bridge?

20 components, from 16 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 Min ssh serial bridge design files?

From the hnz1102/ssh-serial-bridge 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 Min ssh serial bridge design in my own project?

The repository has no license, so all rights stay with hnz1102. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Min ssh serial bridge 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.
