The STAMPS3 is a main control core module, using a Lexin ESP32-S3FN8 main control chip, 8MSPI flash memory, an Xtensa 32-bit LX7 dual-core processor and a main frequency up to 240MHz. It has a built-in 5V to 3.3V circuit, an RGB status indicator, a programmable button, and a 1.27MM/2.54MM spacing lead. It supports SMT, DIP row, and DIP row jump wires. The module is suitable for IoT application scenarios with embedded main control modules. We also stock a version with pin headers pre-soldered.
