Matchboxscope/Anglerfish (ESP32) Flashing Tool
User-friendly tool to flash/upload the firmware for the Matchboxscope/Anglerfish device in the browser:
- Install & update firmware
- Connect device to the WEB-USB Serial interface (work in progress)
- Visit the device's hosted web interface (work in progress)
- Access logs and send terminal commands (work in progress)
Pick your ESP32 PCB and flash the software using the browser! No programming or other software required.
Note: Ensure you have installed the CH340 driver and set the board into boot mode (press first reset => hold it and then reset at the same time).
ESP32 Camera Simple Webcam Server
This flashes the ESP32 Camera Server to the board. here.

ESP32 Camera Simple Webcam Server Advanced
This flashes the ESP32 Camera Server to the board. here. It adds several new features like time-lapse imaging, PWM output, deepsleep, upload-to-github and more. You can add your Wifi Credentials by sending the following json string via USB Serial (a web-based GUI will follow!) {"ssid":"Blynk","password":"12345678"}
