maker100-xiao-esp32s3-sense

Started Feb 26th, 2025

A combination of maker100-eco with a LoRa capable Seeedstudio module for the IoT part.

Also check the curriculum at https://github.com/hpssjellis/maker100-curriculum

Based on the working Maker100-eco course at https://github.com/hpssjellis/maker100-eco but with the Seeedstudio LoRa module

$9.90 USD LoRa Module https://www.seeedstudio.com/Wio-SX1262-with-XIAO-ESP32S3-p-5982.html

and the amazing $13.99 Xiao-Esp32S3Sense https://www.seeedstudio.com/XIAO-ESP32S3-Sense-p-5639.html

More comming.

Present work. tryng to fully understand meshtastic. especially how to communicate with it.

just a reminder about the curriculum

ChatGPT update of the maker100 curriculum with the new xiao-LoRa module. I will change these just need a place to put them.

IoT Internet of Things Connectivity

1. IoT01-WiFi-Webserver: Make your microcontroller into a LOCAL WIFI webserver. Note: Unless your IT department approves, this webserver will not be connected to the internet. my example
2. IoT02-camera-streaming-webserver: Stream your camera feed to a local webpage. This is a default ESP32-S3 program; just uncomment the necessary sections. Find it under Examples → ESP32 → Camera → cameraWebServer.
3. IoT03-sound-streaming: Stream live sound over WiFi. This is challenging, but students can experiment with ESP32-S3's I2S features.
4. IoT04-BLE: Get the microcontroller to connect to an app like NRF Connect by Nordic. Apple ... Android my example BLE coding is tricky; use AI tools for assistance.
5. IoT05-LoRa (Meshtastic Basic): With two Seeed Studio Wio SX1262 modules, create a simple text-messaging system over LoRa. Follow Meshtastic documentation for setup and explore creative use cases like off-grid communication.
6. IoT06-LoRaWan (Advanced): Connect one LoRa module to a LoRaWAN network like TTN or Helium. You’ll need cloud integration and credentials for a gateway. Experiment with sending environmental sensor data.
7. IoT07-Meshtastic Network: Create a decentralized communication network using multiple Wio SX1262 LoRa modules. Test messaging across different distances and obstacles, exploring real-world applications like emergency communication.
8. IoT08-ESPNOW: ESP32 modules can communicate without a router using ESPNOW. Use the default example to send and receive messages between microcontrollers.
9. IoT09-ethernet-poe: If you have an Ethernet module, create a webserver using Ethernet. Advantages: 1. No passwords needed, 2. POE (Power over Ethernet). my example (PortentaH7 with Ethernet Vision Shield).
10. IoT10-multiplexer: Some microcontrollers lack sufficient pins for projects. Use a multiplexer to expand I/O capacity. This is useful for controlling many sensors or displays.
11. IoT11-UART: Connect two microcontrollers using the UART serial protocol (RX/TX crossed). my example
12. IoT12-I2C: Use the I2C protocol to connect and exchange information between two microcontrollers. Note: Pull up SDA and SCL lines to 3.3V using 4.7 kOhm resistors. my example
13. IoT13-SPI: Use SPI (MOSI, MISO, SCK, SS) to exchange information between microcontrollers. This can be difficult, as most MCUs act as controllers while sensors function as peripherals.

New Additions for Seeed Wio SX1262:

1. IoT14-Meshtastic GPS Tracking: Use the Wio SX1262’s Meshtastic capabilities to build a basic GPS tracking system for hiking or cycling.
2. IoT15-LoRa Remote Sensor Network: Deploy multiple LoRa nodes to collect and transmit environmental data (temperature, humidity, air quality) to a central station.
3. IoT16-LoRa Secure Messaging: Implement encryption to send secure messages between LoRa modules.
4. IoT17-LoRa to WiFi Bridge: Use an ESP32-S3 as a bridge to receive LoRa messages and send them to a web dashboard via WiFi.
