Stamp-C3
SKU:C056-B
Description
Stamp-C3 is a cost-effective RISC-V minimum core board. It adopts the ESP32-C3 main control chip from Espressif Systems. It has a built-in RISC-V 32-bit single-core processor, and the clock frequency can reach up to 160 MHz. It is equipped with a built-in 400 KB SRAM and 4MB FLASH, and also integrates 2.4 GHz Wi-Fi. This core board supports security mechanisms such as secure boot, Flash encryption, and digital signatures. Despite its small size, it is extremely powerful in functionality and can meet diverse application requirements of the Internet of Things.
Features
- Supports multiple application forms (Surface Mount Technology (SMT), Dual In-line Package (DIP), jumper wires).
- Equipped with high-temperature plastic armor, and can withstand the reflow soldering temperature (230°C) during SMT process.

USB Driver
Click on the link below to download the driver program that matches your operating system. Select the installation package corresponding to the bit number of your operating system for installation. (If you are not sure which USB chip your device is using, you can install both drivers simultaneously. During the installation of CH9102_VCP_SER_MacOS v1.7, an error message may occur, but in fact the installation has been completed, and you can just ignore it.) When using it, if you encounter a situation where the program cannot be downloaded normally (with prompts such as timeout or "Failed to write to target RAM"), you can try reinstalling the device driver.
| Driver name | Applicable driver chip | Download link |

| CH9102_VCP_SER_Windows | CH9102 | Download |
| CH9102_VCP_SER_MacOS v1.7 | CH9102 | Download |
Port Selection on MacOS
On MacOS, there may be two available ports. When using them, please select the port named wchmodem.
