Get Started with SenseCAP Indicator
Overview
SenseCAP Indicator is a 4-inch touch screen driven by ESP32-S3 and RP2040 Dual-MCU and supports Wi-Fi/Bluetooth/LoRa communication.
The device comes two Grove interfaces, which supports ADC and I2C transmission protocols, and two USB Type-C ports with GPIO expantion pins inside, so user can easily expand external accessories via USB port.
SenseCAP Indicator is a fully open source powerful IoT development platform for developers. One-stop ODM Fusion service is also available for customization and quick scale-up.
Features
- Dual MCUs and Rich GPIOs Equipped with powerful ESP32S3 and RP2040 dual MCUs and over 400 Grove-compatible GPIOs for flexible expansion options.
- Real-time Air Quality Monitoring Built-in tVOC and CO2 sensors, and an external Grove AHT20 TH sensor for more precise temperature and humidity readings.
- Local LoRa Hub for IoT Connectivity Integrated Semtech SX1262 LoRa chip (optional) for connecting LoRa devices to popular IoT platforms such as Matter via Wi-Fi, without the need for additional compatible devices.
- Fully Open Source Platform Leverage the extensive ESP32 and Raspberry Pi open source ecosystem for infinite application possibilities.
- Fusion ODM Service Available Seeed Studio also provides one-stop ODM service for quick customization and scale-up to meet various needs.(please contact [email protected])

Grove
There are two Grove interfaces for connecting Grove modules, providing more possibilities for developers.
Grove is a modular, standardized connector prototyping system and a strong open source hardware ecosystem. Click here to learn more
LoRa®
The embedded Semtech SX1262 LoRa® module enables you to build the LoRa® application and connect your local LoRa sensors to the Cloud via Wi-Fi. For example, you could build a LoRa hub device to connect your LoRa sensors to your smart home ecosystem to implement Matter over Wi-Fi. In this way, the LoRa devices could be connected to the Matter ecosystem via Wi-Fi, without the need to buy a new Matter-compatible device.
