Designed to transform the process of developing and debugging USB-C Power Delivery (UCPD) solutions, the Spark Analyzer is a revolutionary piece of hardware powered by the ESP32-C3 microcontroller. The device is characterized by its compact design, simple operation, and a comprehensive set of power delivery and analysis features, available at a significantly competitive price point.
Hardware and Connectivity
The Spark Analyzer is equipped with an ESP32-C3FH4 microcontroller, a low-power system-on-a-chip (SoC) featuring a single-core RISC-V CPU. It also includes integrated 2.4 GHz Wi-Fi and Bluetooth 5 (Low Energy) connectivity. This wireless chip allows users to control and monitor the Spark Analyzer remotely, and it facilitates seamless integration with other smart devices via Matter.
Power Delivery and Current Monitoring
The device is engineered to provide adjustable voltage output ranging from 5V to 20V, catering to the varying requirements of different projects. Power is conveniently delivered to any connected device through a two-pin screw terminal block on the device. Notably, a Cross Chip sensor measures the electrical current passing through the device using the Hall effect. A built-in software safety feature automatically turns off the output field-effect transistor (FET) in case the current exceeds safe limits. Furthermore, users can monitor the current draw in real-time via a dedicated mobile app.

Mobile App and Open Source Project
The Spark Analyzer is complemented by a mobile app, currently available for Android, and support for iOS via the RemoteXY app. The app displays data from the Spark Analyzer and allows you to control the device in real time. Users also have the option to save the current draw as a .csv file and set the current limit using their phone.
In addition, the Spark Analyzer project is open-source, with a GitHub repository containing detailed project documentation, including code, hardware schematics, 3D enclosure files, and usage instructions.
Availability and Pricing
The Spark Analyzer is currently available on Crowd Supply, aiming to reach a funding goal of $1500. The device is affordably priced at $49, with free shipping within the United States and a $12 shipping fee applicable for international orders. The expected shipping date is August 4, 2024.
With wireless connectivity as its standout feature, the Spark Analyzer holds a competitive edge over other alternatives in the market. It is a noteworthy contribution to the domain of small form factor and single-board computers and is expected to be highly impactful.
