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.
