Description

 

CANADUINO® STM32 Blue Pill – Black Pill Screw Terminal Adapter with 3.3V LDO and RTC Battery Backup fits the common “Blue Pill” and “Black Pill” modules.

The STM32 Screw Terminal Adapter is a DIY soldering kit that supports different “STM32Duino” modules with STM32F103 and STM32F4x1 series MCUs.

We added a powerful voltage regulator to extend the power supply voltage to 30VDC, and the current delivery capability for the 3.3V line to 250mA (depending on input voltage).

Furthermore a battery holder for a CR1220 lithium button cell – necessary for real-time clock and to keep register values without a power supply – was added to the module.

The STM32 Screw Terminal Adapter shows the pinout for “Blue Pill” STM32F103 modules in one direction, and for “Black Pill” STM32F4x1 modules in the other direction (upside down).

Dimensions: 80 x 50mm

The STM32 Blue Pill – Black Pill Screw Terminal Adapter comes with the SMD parts factory assembled. However, the through-hole parts are included in the bad but need soldering.

The backup battery CR1220 is not included.

Attention: The power dissipation of the on-board voltage regulator must not exceed 2W (at room temperature). Please do the math and calculate the power dissipation, depending on your input voltage and current drawn by your application, to avoid overheating.

Please read this great review written by one of our customers (for the older version).
