The Dendrite-S3 is a robotics development board powered by the ESP32-S3, featuring an on-board LiPo charge/discharge circuit, and 34 GPIO.
Why did you make it?
I created this to provide an affordable, open-source robotics controller to help developers and hobbyists build sophisticated robots more easily.
The Dendrite-S3 serves as the core controller for upcoming modular robot kits, handling motor control, sensors, and wireless communication. Yet it remains flexible enough for electronics prototyping and custom designs.
So whether you are looking to build mobile robots or create custom electronic devices, the Dendrite-S3 delivers a perfect blend of ready-to-go robotics capabilities and DIY extensibility.
What makes it special?
This board breaks out 34 of the esp32-s3 pins, along with the 8 MB PSRAM, and 16MB Flash allows for relaying large amounts of sensor data. This makes it for using with complex robot projects.
This may be a bad idea placing i2c connector near the wifi antenna plug, but this is the reason I went for the non-pcb antenna. I will Have to order test boards to check how well this design works.
This is the Robot Driver Board for the Lab-Rat a series of robot kits as a part of the parent project: Behavioral Robotics.
At this point, the board is already up for sale on Tindie, but is can still be improved upon. The board is currently being sold as a robotics development board, but will be the driver for the first series of kits as they roll out. I will post other components on my page in the future.
Some things that still need to be done for this board:
