SenseCAP Indicator Abstract

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 iot@seeed.cc)
