Stamp-S3A
SKU:S007-V033
Description
Stamp-S3A is a highly-integrated embedded module based on the Espressif ESP32-S3FN8. It is equipped with a 240 MHz Xtensa® 32-bit LX7 dual-core processor, integrates 8 MB Flash, a programmable RGB LED, and a user button. The deeply-optimized 3D antenna design offers stronger wireless communication performance. Twenty-three GPIOs are broken out and provided via 1.27 mm / 2.54 mm pitch SMT/DIP pin headers or sockets, allowing effortless PCB integration and enabling developers to build applications rapidly.

Download Mode
To enter download mode, hold the G0 button on the Stamp-S3A before powering on, then release it after power is applied.
Additional Notes
- ESP32-S3 pins G0 and G46 are strapping pins that determine the boot mode. By default, G0 is pulled-up and G46 is internally pulled-down, allowing the chip to boot from SPI Flash normally. Do not pull G46 high before the chip boots; otherwise, it cannot start correctly. Refer to the Strapping-Pin section of the ESP32-S3 datasheet for details.
- An SPI interface for a TFT display is reserved on the back of the module. The compatible FPC connector specifications are 8 PIN and 12 PIN.
