$60 M5Stack CoreS3 ESP32-S3 IoT controller comes with 2-inch display, VGA camera, multiple sensors

M5Stack CoreS3 is a battery-powered ESP32-S3 IoT controller with WiFi and Bluetooth connectivity, a 2-inch touchscreen display, a 0.3MP camera, a microSD card slot for storage, several sensors, plenty of I/Os, a USB Type-C OTG port, as well as a 9V to 24V DC input port.

That’s the second ESP32-S3 IoT controller from M5Stack we’ve seen this year, as the CoreS3 follows the smaller M5Stack AtomS3 with a 0.85-inch display, only a few I/Os, and fewer features overall although it does come with an IR transmitter that’s missing from the larger CoreS3.

As usual, M5Stack says the controller is programmable with the Arduino IDE or UIFlow visual programming tool, but points us to a currently empty repository on GitHub for Arduino code samples… A few more technical details can be found on the documentation page.

M5Stack is selling the CoreS3 IoT development kit for $59.90 on its own store.
