ESP32-Based 3D Printed Fish Feeder RC Board v2

The original plan for this project was to create a fun RC Paddle Boat. However, during the project, I came up with the idea of adding a fish feeder. This means that besides enjoying a ride around the lake, the boat can also be used as a bait board for fishing, and can deliver food and medicine in pellet size needed by fish to otherwise inaccessible areas like Mangrove.

The RC controller and the Boat communicate using the ESP-NOW protocol, eliminating the need for a separate radio controller circuit and reducing the complexity and cost of the construction. In my test, I was able to achieve a range of around 200m (line of sight). Additionally, the boat stays afloat with the help of two water bottles.

I also build an RC controller for this . you can control the movement of the boat using a single joystick also you can drop the payload by pressing the pushbutton on top of the joystick. you do not need any pairing for RX and TX it will done automatically. you can switch on the TX by pressing the push button on the side. You can also see the battery indicator on the top. TX is rechargeable through USBC

This project has been updated to Version 2.0

I have designed a PCB main board for the receiver section to simplify the complexity of the project. A 5V regulator is included to power the Xiao ESP32-C3, allowing you to increase the voltage in the main boost converter, enhancing the motor's speed and power. You can find the Gerber file attached to step 1 of the project in my Instructables.i used PCBWay for ordering this PCB for this project

you can find all SLT files, and building instructions. 3d project file, code , and wiring digram on my Instructables
