This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...

WORK IN PROGRESS - NOT READY FOR MANUFACTURE
Looking for collabortors to get this design ready for a a production build.
Project to build a 7S 5P 18650 battery state monitoring system.
Note: the BQ76930 is specifically configured for a 7 series pack.

This board forms part of a 9 * 18650 battery charger using 3 INA3221 chips to capture the voltage/current during charging.
The I2C INA3221 register data is written via the WEMOS PRO MINI to an INFLUX database every 10 seconds. The data is surfaced through a GRAFANA dashboard. Each INA3221 has its own I2C address hardwired through links to the A0 pin i.e. (0x40, 0x41, 0x42)

One of older projects imported from Eagle. It has three 18650 cells onboard and can charge them. Relays are needed for switching cells in parallel for charging or in serial to give 10-12 volts for LED strip.
Although USB connector used, it needs about 7,5 volts for success charging due to used LM3177 voltage drop.
Project was made and tested from Eagle, but imported to EasyEDA without any tes...
