CANADUINO® STM32 Blue Pill / Black Pill Screw Terminal Adapter with 3.3V LDO and RTC Backup

This versatile screw terminal adapter is designed to fit the popular STM32 "Blue Pill" (STM32F103) and "Black Pill" (STM32F4x1) modules. It’s an ideal companion for your STM32Duino projects, offering easy wiring access and enhanced power handling.

Key Features:

  • Wide Compatibility: Supports both STM32F103 and STM32F4x1 series microcontroller modules.

  • Improved Power Supply: Integrated 3.3V low-dropout (LDO) voltage regulator allows input voltages up to 30VDC and delivers up to 250mA to the 3.3V rail (depending on input voltage and thermal conditions).

  • RTC Backup Support: Includes a CR1220 battery holder for real-time clock operation and register retention when main power is off. (Battery not included.)

  • Clear Pin Labeling: Pinouts are labeled for STM32F103 modules on one side and STM32F4x1 modules on the reverse side (adapter must be flipped accordingly).

  • Compact Size: 80 x 50 mm footprint.

Assembly Notes:

  • Comes with all surface-mount components pre-installed.

  • Through-hole components are provided and require soldering.

  • CR1220 backup battery is not included.

Important:

To prevent overheating, the onboard regulator’s power dissipation must not exceed 2W at room temperature. Be sure to calculate power loss ((Vin - 3.3V) × Current) based on your application to ensure safe operation.
