Stamp-S3A PIN1.27
SKU:S007-PIN127-V033
Description
Stamp-S3A PIN1.27 is a highly-integrated embedded module based on the Espressif ESP32-S3FN8. It features 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 delivers stronger wireless performance. Twenty-three GPIOs are broken out and a 1.27 mm-pitch SMT pin header is pre-soldered, providing an even smaller footprint for high-density PCB integration and enabling developers to build compact applications quickly.

Download Mode
To enter download mode, hold the G0 button on the Stamp-S3A PIN1.27 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, enabling the chip to boot from SPI Flash normally. Do not pull G46 high before the chip boots; otherwise, the chip will fail to start. 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. Compatible FPC connector specifications are 8 PIN and 12 PIN.
