A Product-Grade Portable USB Ammeter and Low-Power Measurement Analyzer

+ + + + + + +
+ + +
+ +--- + +## 📖 Project Introduction + +**Power-Pico** is more than just a USB ammeter. It is a **high-precision, low-power analysis tool** designed specifically for embedded developers. To overcome the physical limitations of traditional ammeters in the μA-level measurement, Power-Pico adopts an innovative **multi-range auto-switching sampling** design, achieving full-range coverage from $1\mu A$ to $5A$. + +
+ Display +
+ +### ✨ Core Features +- **μA-Level High Precision**: Utilizes the INA190 zero-drift amplifier with three-resistor segmented sampling. +- **Protocol Trigger**: Supports PD2.0 PPS protocol triggering, with up to 20V/5A output. +- **High-Performance UI**: Based on STM32F411 + LVGL v8.3, providing a smooth real-time waveform display. +- **Cross-Platform PC Client**: Comes with the Power-Pico Client developed with PySide6, supporting data export and real-time power analysis. +- **3D Printed Enclosure**: Provides a complete design for a 3D printed enclosure and acrylic panel. + +--- + +## 🛠️ Hardware Parameter Analysis + +| Module | Model | Advantage | +| :--- | :--- | :--- | +| **MCU** | STM32F411CEU6 | 100MHz high frequency, supports DSP instructions to accelerate waveform processing | +| **Current Sensing** | INA190 | 0.5nA input bias current, the core guarantee for μA-level measurement | +| **ADC** | 12-bit (STM32 Internal) | Achieves high-speed stable sampling above 10kHz with DMA | +| **Screen** | 1.54" TFT (ST7789) | 240x240 resolution, high-contrast display | + +--- + +## 🚀 Quick Replication + +### 1. Hardware +Solder the hardware yourself, or purchase a pre-soldered and assembled kit from Taobao. +LCSC Open Source Hub page: https://oshwhub.com/no_chicken/powerpico + +### 2. Firmware Compilation and Flashing +The project is developed based on Keil MDK: +1. Clone the repository: `git clone https://github.com/kingham/Power-Pico.git` +2. Flash the BootLoader via the SWD port. +3. Compile PowerPico yourself. The generated `.bin` file can then be flashed using the PowerPico Client. + +### 3. Assembly + +The physical assembly is shown in the figure below: + + +The exploded 3D view is as follows: + +
