Stamp-C3
SKU: C056-B
Description
Stamp-C3 is a cost-effective RISC-V minimal core board. It uses the Espressif ESP32-C3 as the main control chip, which features a RISC-V 32-bit single-core processor with a clock speed of up to 160 MHz. It comes with 400 KB SRAM + 4MB FLASH and integrates 2.4 GHz Wi-Fi. The core board supports security mechanisms such as secure boot, flash encryption, and digital signatures. Despite its compact size, it is highly functional and can meet diverse IoT application needs.

USB Driver
Click the link below to download the driver that matches your operating system. Select the installation package corresponding to your operating system's bit version. (If you are unsure of the USB chip used by your device, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but it is actually installed successfully, so you can ignore the error.) If you encounter issues with downloading the program (e.g., timeout or "Failed to write to target RAM"), try reinstalling the device driver.
| Driver Name | Applicable Chip | Download Link |
