Openmote-B (Wireless environmental sensors)
General Description
The OpenMote B is an advanced low-power wireless node specifically designed for IEEE 802.15.4 and TSCH (Time-Slotted Channel Hopping) networking. It is based on the TI CC2538 system-on-chip (SoC), which integrates an ARM Cortex-M3 processor with a 2.4 GHz IEEE 802.15.4-compliant radio, enabling energy-efficient and deterministic communication.
When used with Contiki-NG, OpenMote B fully supports the 6TiSCH stack, leveraging TSCH for synchronized multi-hop communication and channel hopping to enhance reliability and mitigate interference. The node provides 128 KB of RAM, 512 KB of Flash, and a cryptographic accelerator, making it well-suited for secure IoT and industrial wireless sensor networks (WSNs).
Additionally, OpenMote B features multiple GPIOs, I2C, SPI, and UART interfaces, allowing integration with external sensors and peripherals. Its compatibility with RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks) and CoAP ensures seamless deployment in constrained IPv6-based IoT ecosystems.
