Starter Kit with free Course for all Electronics Neophytes and Enthusiasts

Seeed Studio has provided the Grove Starter Kit along with free and detailed courses for you quickly get started with microcontrollers and electronics, regarding all the Seeed Studio XIAO boards, promising you a great learning experience.

Not only programming but also electronics knowledge is not required, you will be taken step by step, from understanding the basic concepts to exercising the simple projects individually, finally being able to build complex, interesting, wearable projects on your own, owing a practical electronic product prototype from the course.

You can have access to the Seeed Studio Grove ecosystem by connecting it to the compatible Seeed Studio XIAO expansion board. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs.For example, you can utilize the accelerometer on XIAO nRF52840 Sense combined with Edge Impulse to enable motion recognition by connecting with a Grove - OLED Display 0.66" (SSD1306)- IIC - 3.3V/5V. Get started and explore the infinite possibilities of the Seeed Studio XIAO series!

If you are interested in programming embedded machine learning, we have Codecraft visual programming that can help you quickly start your own TinyML project. And we have set up a #tinyml channel on our Discord server, please click to join for 24/7 making, sharing, discussing, and helping each other out.

We already have 10 XIAO products based on different solutions in the XIAO family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.

Application 1: Smart Private Garage

Materials: XIAO ESP32C3 *2, Grove - Button *1, Grove - Relay*1

Description:

This is a peer-to-peer WiFi communication application, since two XIAOs detect each other via Wifi, the garage door will open or keep opening, and vice versa.

Improvement:

It is nice to add an ultrasonic distance sensor to measure the car-to-door distance and an OLED screen to check the status of the garage. If you want an onboard voice sensor to command the door to open with vocal instruction, try our XIAO BLE Sense.

Application 2: Remote Forest Tracker

Materials: XIAO ESP32C3 *1, Grove - Wio - E5 *1, Grove - GPS *1

Description:

Thanks to the tiny size of the XIAO series, it is suitable to make the wearable devices, such as a small pet trackers. This wearable device can be used as a simple GPS-Tracker which will lock its current location and publish other data via LoRa.

Improvement:

A compass that shows direction and distance is a great added value to the tracker that you could consider. Meanwhile, publishing altitude, speed, or other parameters could bring more scenarios to this tracker. Besides, the chip ESP32-C3 allows this tracker to communicate over WiFi or BLE, and therefore, we can upload the tracker’s data or realize the Long Range-to-MQTT bridge as well.

Probably you are worried about the wireless capability of the above application of XIAO ESP32C3, and We have a 2.4GHz Rod Antenna for XIAO ESP32C3 which increases the wireless capability of the XIAO ESP32C3, The antenna is certified TELEC and XIAO ESP32C3 is compatible with Antenna, Check 2.4GHz 2.81dBi Antenna for XIAO ESP32C3 - Seeed Studio to see more!
