Blue pill vbatI noticed a huge difference with the Blue Pill LSE timing, depending on whether VBB was connected to 3.3V or not. The system that I have aims at "low hanging fruit". I de-populate the pins PC14 and PC15 because they are OSC32in and OSC32out. That reduces the capacitance and coupling to external hardware, without any significant mods to the board.Blue Pill developmet board for STM32F103c8t6 PTOTO BoardBlue Pill STM32F051C8T6 Board Microcontroller Internal memories Oscillators Power Regulator PCB Remarks Warning: The +5V pins on this board are directly connected to the +5V pin of the USB connector.

Basics Of RTC DS1307. The DS1307 serial real-time clock (RTC) is a low power, full Binary-Coded Decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information.This means that it's possible to sustain Blue Pill in Deep Sleep just by supplying a bit of Backup Power to the VBAT pin, while the rest of Blue Pill (running on Main Power) is powered down.

I believe as long as the RAM can keep the value, the RTC should also keep running. ahull(blue pill) gndd c12 100n c11 100n c9 100n c8 100n r16 10k r15 10k r14 10k r13 10k r12 10k r11 10k gndd gndd gndd c1 100n c10 100n gndd jp1 boot0 r1 100k c3 100n c2 100n c4 100n gndd c5 10u r6 1k c6 10u gndd gndd c7 10u ... vbat 1 vdd 24 vdd 36 vdd 48 vdda 9 vss 23 vss 35 vss 47 vssa 8 u3 stm32f103c8tx r2 100k gndd gndd gndd 1 2 3 j1 input r5 ...BluePill ARM STM32 STM32F103C8 Vývojová deska | Vývojová deska kompaktních rozměrů osazená mikrokontrolerem ARM®Cortex®-M3 STM32F103C8.
