BatOne has an advanced Li Ion charger circuit with indicator LED's that indicate the status of the charging cycle. For obvious reasons, when the device is running from a battery these indicator LED's are disabled to minimize power consumption. The status from the charger can also be read by the ESP8266 via an I2C bus allowing the processor to send messages to a user when the charging status changes.
The board is also equipped with a 3.3Volt synchronous boost converter that provides the power to the node.IT stack. The linear on board regulator on the ESP210 is disabled automatically when the BatOne is mounted to further reduce the power consumption.
This module is shipped with the NodeIT stack headers not soldered to the module. You will need a reasonably good solder iron to solder these to the PCB.
