Summary of Contents for AZ-Delivery D1 Mini Battery Shield

  • Page 1 Quick Start D1 mini Battery Shield...
  • Page 2 Areas of application The module is specially designed for applications in prototyping, education, research and teaching. It is used to develop and test chargers and to impart practical knowledge about lithium-polymer batteries and electrical circuits. Required knowledge and skills The use of the module requires a sound knowledge of electrical engineering, in particular the handling of Li-Po batteries and chargers.
  • Page 3 can lead to injuries. Note: Ensure that there is no direct contact with live parts during operation. Caution: Overheating can cause damage to the module and the batteries. Note: Ensure that the module is sufficiently ventilated during operation and monitor the temperature regularly. Caution: High temperatures can significantly shorten the service life of the batteries and the module.

  • Page 5 Introduction The D1 Mini Battery Shield provides a convenient solution for powering the D1 Mini module with a Li-Ion/Li-Po battery. It contains an integrated DC-DC boost converter (step-up) that efficiently raises the battery voltage from 3.7 V to 5 V and provides a reliable power source for the D1 Mini module and associated shields with a robust power supply of up to 1 A.

  • Page 7 Overview Components Name Description of the Battery connection Connection to lithium battery (normal 3.3-4.2V) Micro Usb Charging connection ( normal 5V) Green Led lights up when the charging process is complete Red led lights up when charging Jumper J1 Setting the maximum charging current, 0.5A or 1A.
  • Page 8 Using the Jumper J1 J1 is a jumper that controls the maximum charging current for your Shield battery when it is charging. It has two settings: ● 0.5A : This is the default setting. If J1 is not soldered, the maximum charging current is set to 0.5 amps.
  • Page 9 Consult the operating instructions for the battery and charging components in order to obtain the most accurate instructions possible. Using the Jumper J2 To measure the battery voltage, we need to connect A0 to the battery by soldering jumper j2. The D1 mini already has an internal voltage divider that connects pin A0 to the ADC of the ESP8266 chip.

  • Page 10: Battery Polarity

    Battery polarity Ensure correct alignment when connecting the battery to the shield. Align the PH2-2mm connector with the shield in the correct direction. You can also solder the battery directly to the shields. There are markings or stickers that indicate the positive pole (+) and the negative pole (-). Make sure that you align the positive pole of the battery with the positive mark on the shield and the negative pole with the negative mark.
  • Page 11 Test example: Measuring the battery voltage It is very useful to know the remaining voltage level of the battery in order to predict charging (or replacement). The D1 Mini module has an analogue input that can be used to monitor the state of charge of the battery.
  • Page 12 delay(1000); This code reads an analogue voltage from a sensor connected to pin A0, converts and then prints the raw analogue-to-digital conversion value, the voltage in volts and the percentage of the maximum voltage (4.2 V) that the battery value represents. These values are output to the serial monitor in a continuous loop every second.
