About the XiaoMistMaker PCB
XiaoMistMaker is an open source PCB design by Dav1dyang, published on GitHub under the MIT license. It is a 2-layer board measuring 17.8 × 21 mm, with 17 components from 17 distinct parts.
Other key parts include the AP7361C-3.3V and INA180A3. By type, the board carries 7 resistors, 3 capacitors, 2 ICs, 1 transistor, 1 connector and 1 LED.
From the project
An open-source, low-cost ultrasonic mist maker designed to share commercial humidifier circuits and empower creators with accessible, well-documented hardware.
1. Upload XiaoMistMakerV0-1.zip (defaults are fine; 1.6 mm, any color). 2. Enable SMT assembly, upload bom.csv + positions.csv`. 3. Hand-solder afterwards: PH-2.0 piezo connector, XIAO headers.
- INA180 — current-sense amp (A3 = 100 V/V) - UCC27511A — single-channel gate driver - DMT10H009LCG — MOSFET - Seeed XIAO ESP32-C6
