5V power indicator on board

(1) Adopt the world's key material-LiCo02

The idea behind this plate is to simplify construction

there is a potentiometer that can be further used to control the threshold point of the vibration

STM32F412RET6 STM32F4 Development Board original (The BlACKPill) USB 2.0 Card Reader High Speed 15in1 5V power indicator on boardIntroduction : STM32F412RET6 family is based on the high performance Arm Cortex M4 32 bit RISC core operating at a frequency of up to 168 MHz. The Cortex M4 core features a Floating point unit (FPU) single precision which supports all Arm single precision data processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F412RET6 a family
