About the Helix vape PCB

Helix vape is an open source ESP32 PCB design by stevensun369, published on GitHub. It is a 2-layer board measuring 30 × 97 mm, with 77 components from 51 distinct parts.

Its main chip is the ESP32-C6-MINI-1U, from the ESP32 family. Other key parts include the LM5175PWP, LMR62014XMF, MCP4726, ADS1015IDGS and LP3986-30B3F. By type, the board carries 27 resistors, 18 capacitors, 7 ICs, 4 transistors, 3 connectors and 3 diodes.

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

From the project

KiCad design for an ESP32-C6 buck-boost vape mod power board — LM5175 stage, 1.0–10 V @ 80 W, with full JLCPCB production files.

KiCad hardware design for the Helix temperature-control vape mod: a single-cell, USB-C powered board capable of delivering 1.0–10 V at up to 80 W into a heating coil, with closed-loop current/voltage sensing and an ESP32-C6 running the Helix-FW firmware.

The power stage is based on TI's PMP20410 reference design, re-implemented and integrated with the MCU, sensing, and user-interface circuitry on a single board.

Helix vape: common questions

What microcontroller does the Helix vape use?

The Helix vape is built around the ESP32-C6-MINI-1U, from the ESP32 family.

How big is the Helix vape PCB?

The Helix vape measures 30 × 97 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Helix vape?

77 components, from 51 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 Helix vape design files?

From the stevensun369/helix-vape-pcb 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 Helix vape design in my own project?

The repository has no license, so all rights stay with stevensun369. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Helix vape 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.
