A working demo of ESP8266 ESP-01S UART WiFi module running on STM32F103C8T6
- STM32F103C8 board
- ESP-01S: ESP8266 Wi-Fi module
- UHF RFID module (optional)
- USB2TTL: PL2303 or CH340 or FT232 or CP2102
- ST-Link or J-LInk
- Laptop & Wi-Fi hotspot
Refer below table to connect ESP-01S pins with STM32 pins:
| ESP-01S | STM32 | USB2TTL | RFID |
|---|---|---|---|
| GND | GND | GND | GND |
| TX(GPIO1) | PA3 | ||
| RX(GPIO3) | PA2 | ||
| 3.3V | 3.3V | 3.3V | |
| PA10 | TX | ||
| PA9 | RX | ||
| PB10 | RX | ||
| PB11 | TX |
Use ST-Link to upload the code to STM32.
Connect ST-Link with STM32F103C8T6 Development Board
G -- GND
