I built (and currently testing) a 4 port automated PCB test & programming tool. I needed a way to produce a bunch of PCBs efficiently and couldn't find a solution that was flexible and didn't cost many thousands of dollars. I made a simple tool to solve this.

Features

    - 4-channel DUT interface with individual power control via TPS22992
    - JTAG multiplexer for programming (not exclusive to JTAG)
    - Power monitoring using PAC1954 for per-channel current/voltage measurement
    - Raspberry Pi Pico for control logic and automation
    - USB interface through Pi Pico USB-CDC for host communication (1 port for each DUT)
    - 1.8V - 5V IO support
    - MicroPython support for test script automation

Very cool project. Congrats. I will be trying this out.

Two other project I saw that are somewhat related for those interested:

1. reddit community (r/xteinkereader) building an OS like ebook reader app for a small chinese ereader based on esp32-s3

2. Linux port for the esp32-s3. Interestingly, the S3 has an MMU but I don't think it was used in this project.

For those that want more details on how the software works, this guy goes into a bit more detail for his version

If you just want a simple UI editor and don't want to pay for the official tool, give GUI Glider from NXP a try.

Super impressive project, especially for what seems to be your first embedded project. I haven't played with microPython/uOTA so this was an interesting read.

Since you mentioned the water meter Flume, I wanted to shamelessly plug my open source water meter that I'm currently developing. It also uses the ESP32 so I thought you might be interested.

I started working on my opensource water meter again (https://y-drip.com/). Hardware is basically done so I'm working on the backend website for those that don't want to setup their own server. More technical details here: https://hackaday.io/project/191398-ydrip

I'm a seasoned software engineer with extensive experience in embedded systems, real-time communication, and full-stack development. My background includes designing innovative hardware and software solutions for various applications.

Key Projects:

    - Real-time Audio Communication Device: Developed a device supporting 16 participants over 700 meters with 18-hour battery life using STM32 and Silicon Labs EFR32.
    - Android ROM Customization: Customized Android ROM for a video kiosk, added native USB camera support, and developed an over-the-air A/B update method.
    - Innovative Water Meter Solution (Y-Drip): Designed a product for real-time water usage data and leak detection with ultra-low power consumption.
    - Full Stack Development (Scalp Radar): Created a SAAS website for futures traders using Python, Django, and C#, with an automated license management system.

I'm currently seeking opportunities to leverage my skills in innovative projects, whether in embedded systems, software development, or full-stack applications. Open to remote work or on-site positions.
