The company Particle (formerly known as Spark) yesterday announced the third generation of its microcontrollers for the Internet of things. The main feature of the new products is support for Mesh networks.
Argon
Wi-Fi (based on ESP32) + BLE
802.11 b / g / n support
2.4 GHz up to 150 Mbps
Integrated onboard 2.4GHz antenna
Boron
2G / 3G or LTE (based on ublox SARA-U260) + BLE
LTE CAT M1 / NB1 module with global hardware support
LTE M1 SIM support via Particle MVNO (US / Mexico only)
Dual SIM support (Nano 4FF and MFF2)
Xenon
Low Power Mesh node (BLE)
On-board 2.4GHz mesh antenna
U.FL connector for external antenna
Argon and Boron can act as gateways through which cheap Xenons can access the network. The technology by which the mesh network is built is based on Nest's OpenThread .
The boards will start shipping in July 2018. Special prices are available for pre-order:
Argon - $ 19 $ 15
Boron LTE - $ 39 $ 29
Boron 2G / 3G - $ 59 $ 49
Xenon - $ 12 $ 9
In addition, for those who pre-order within 24 hours, delivery will be free.
