The Boron LTE is a powerful LTE CAT-M1 enabled development kit that can act as either a standalone cellular device or LTE enabled gateway, repeater, or endpoint for a Particle Mesh networks.
Equipped with the Nordic nRF52840 and u-blox SARA 410 processors, the Boron has built-in battery charging circuitry which makes it easier to connect a Li-Po battery and 20 mixed signal GPIOs to interface with sensors, actuators, and other electronics.
The Boron is great for connecting existing projects to the Particle Device Cloud or as a gateway to connect an entire group of local endpoints where Wi-Fi is missing or unreliable.
