1. INT101 Introduction

LiBat™ INT101 is the cloud connection board of a LiBat™ BMS. It carries a 2G GSM modem, which links the BMS to the LiBat™ cloud over the cellular network, and a GNSS module, which adds the position of the battery. The INT101 sits on top of the BMS and plugs onto its extension port; it takes its power from the BMS and needs no supply of its own. The BMS firmware runs the modem and the GNSS module, so there is nothing to set up on the board itself.

Note

The cloud connection of a BMS is set up by LiBat™. Contact LiBat™ before you order, and order the BMS together with the INT101: the extension port of the BMS is fitted at the factory for it.
