AtomS3R

SKU:C126

Description

AtomS3R is a highly integrated programmable controller based on the ESP32-S3 main controller. It features the ESP32-S3-PICO-1-N8R8 main controller with built-in WiFi, 8MB onboard FLASH, and 8MB PSRAM. It comes with a 0.85-inch color IPS screen, with a programmable button beneath the screen. The device includes a 5V to 3.3V power circuit, a built-in three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 attitude sensor. It also has a Type-C interface for power supply and firmware downloads, along with a HY2.0-4P expansion port. Six GPIO and power pins are reserved at the bottom for easy expansion. Compared to previous products, the 3D antenna of the AtomS3R has been enhanced, offering better performance and greater stability. The product measures only 24x24x12.9mm, making it suitable for various embedded smart device applications.

Download Mode
press and hold the reset button (about 2 seconds) until the internal green LED lights up, then release the firmware. At this time, the device has entered download mode, waiting for burning.
schematics
When controlling the LCD backlight, the PWM frequency is recommended to use 500Hz.
