Overview
Color brick is a set of LoRa-based modular development kit launched by Manthink. The kit is mainly composed of core board BC series, Power Board BP series and sensor BS series. BC series core board has standard hardware interface, BP power supply module and BS sensor module can be plugged into BC board through standard interface to form different sensors. BP series different types
of power supply can support USB 5V power supply, rechargeable lithium battery, primary lithium battery interface, button battery interface, to adapt to different application scenarios. BS series can develop or directly purchase different sensors according to
users' needs, such as GPS positioning sensors, temperature and humidity sensors, door magnetic sensors, water immersion sensors, 485 interfaces, etc.
Main features* Supports the LoRa/LoRaWAN uplink protocol.
* Built-in EB development framework, provides SDK, and supports periodic tasks and low power consumption through API.
* Fast development
* Flexible combination
* Ultra-small size (40x 40mm) can be flexibly plugged into other shells or carrier plates
* Supports powerful delivery capabilities
* Free LoRaWAN core network support
* Supports 4 brick interfaces
