This project is to connect 1$ Raspberry Pi RP2040 MCU to Azure IoT by using a ESP32-C3 SoC as network processor.
The Application is a standard Azure IoT example built on Azure IoT middleware for Azure RTOS and it leverages LwESP project to get WiFi connectivity supported. A custom offload network driver is provided to integrat with NetX Duo 6.1.8 offload driver.
The demo is verified on Raspberry Pi Pico and ESP32-C3-DevKitM-1 hardware, and it can be easily ported to other board like Arduino Nano RP2040 Connect.
| Signal name | Raspberry Pi Pico | ESP32-C3-DevKitM-1 |
|---|---|---|
| 3V3 | J0-36 | J1-2 |
| GND | J0-38 | J1-1 |
| TX | J0-6 (UART1-TX) | J3-9 (UART1-RX) |
| RX | J0-7 (UART1-RX) | J3-8 (URAT1-TX) |
| RESET | J0-4 (GP2) | J1-7 (EN) |
ESP32-C3 must be programmed with ESP-AT firmware. Refer to this link for pre-built binary and document.
