- Blue Pill 1 and MCP2551 1:
- Connect Blue Pill 1 (TX) to MCP2551 1 TXD
- Connect Blue Pill 1 (RX) to MCP2551 1 RXD
- Connect both GNDs together
- VCC of MCP2551 to 5V output of Blue Pill
- Blue Pill 2 and MCP2551 2:
- Same as the first set, replacing "1" with "2" in designators.
2. CAN H and CAN L between MCP2551 Breakout Boards- This connection is for programming/debugging purposes:
- Connect STLink SWDIO to Blue Pill SWDIO
- Connect STLink SWCLK to Blue Pill SWCLK
- Connect GND to GND
4. USB to Serial Converter to Blue Pill- Use this for UART communication/debugging purposes:
- Connect USB to Serial Converter TX to Blue Pill A9 (RX)
- Connect USB to Serial Converter RX to Blue Pill A10 (TX)
- Connect GNDs together
5. NTC Thermistor Connection- Connect one side of the NTC Thermistor to 3.3V on the Blue Pill.
- Connect the other side of the NTC Thermistor to one side of a 10kΩ resistor.
- Connect the other side of the 10kΩ resistor to GND on the Blue Pill.
- Connect the junction between the NTC Thermistor and the 10kΩ resistor to an analog pin on the Blue Pill, say A0, for temperature reading.

- Connect MCP2551 VCC to Blue Pill 5V (via a voltage regulator if your MCP2551 requires 5V).
- Connect all GNDs together.
2. Connecting MCP2551 CAN Transceivers for CAN Bus:- Connect MCP2551 1 CANH to MCP2551 2 CANH, and MCP2551 1 CANL to MCP2551 2 CANL.
3. Connecting STLink v2 debugger to a Blue Pill:- Connect STLink SWDIO to Blue Pill's Pin PA13 (SWDIO)
- Connect STLink SWCLK to Blue Pill's Pin PA14 (SWCLK)
- Connect a GND pin from STLink to GND on the Blue Pill
4. USB to Serial Converter to Blue Pill Connection:- Connect USB to Serial Converter TX to Blue Pill PA10 (USART1_RX)
- Connect USB to Serial Converter RX to Blue Pill PA9 (USART1_TX)
- GND from the converter to GND on the Blue Pill
5. Connecting the NTC Thermistor:- Connect one side of the NTC Thermistor to Blue Pill's 3.3V.
- Connect the other side of the NTC to one side of a 10kΩ resistor (R1).
- Connect the other side of the resistor (R1) to GND.
- Connect the junction between the NTC Thermistor and R1 (voltage divider output) to Blue Pill PA0 (ADC_IN0).
