Product Description:
Seeed Studio XIAO ESP32C3 has equipped a highly-integrated ESP32-C3 chip, built around a 32-bit RISC-V chip processor with a four-stage pipeline that operates at up to 160 MHz.
The board equips highly-integrated ESP32-C3 SoC. The chip has been installed with a complete 2.4GHz Wi-Fi subsystem which means it supports Station mode, SoftAP mode, SoftAP & Station mode, and promiscuous mode for multiple Wi-Fi applications. It works under an ultra-low power state, also supporting features of Bluetooth 5 and Bluetooth mesh. There are 400 KB SRAM & 4 MB Flash on the chip,
Application:
Internet of Things
Wearable devices
Health monitoring
Education
Low-Power(LP) networking
Rapid prototyping
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 here to see more!
