S3

The Premier ESP32 With Everything On Board That You Can Imagine

The S3 is the currently most powerful *ESP32 family member combining almost all features in one chip.

Some infrequently used features like Hall Sensor and DAC were removed in exchange for 10 more GPIO pins, a temperature sensor, and BLE 5.0 support.

Compared To ESP32 WROOM/WROVER

Here is the list of removed or reduced features compared to ESP32:

Feature Removal
Size 7x7 instead of 5x5
SRAM reduced from 520 to 512
ROM reduced from 448 to 384
LED PWM reduced from 16 to 8
DAC removed
SD Slave removed
Hall Sensor removed
Ethernet Removed

New Features

This is what’s new:

Feature Addition
Bluetooth BLE v5.0 instead of BLE v4.2
ADC increased # of channels from 18 to 20
Touch 14 instead of 10
Temperature Sensor added
GPIO extended from 34 to 45
SD Host extended from 1 to 2
USB OTG added

In addition, the S3 comes with AI Acceleration Support: the MCU (math coprocessor) is tailored towards the kind of vector calculations needed in AI applications.

Comments

Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.

Discussions

For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
