About this item

Please note that many low-cost counterfeit versions of this module are available in the market. These often use substandard ICs, leading to reliability issues such as detection failures on computers and programming errors. In contrast, every board we sell is thoroughly tested for functionality and sourced from trusted, high-quality suppliers to ensure performance and reliability. We also offer a variant featuring the STM32F103C8T6 microcontroller, which provides expanded capabilities, including 64KB of flash memory for larger programs and additional SPI and I2C ports. Be sure to check out this enhanced version for more demanding applications and improved flexibility.
