Description:
The Wemos D1 Mini Battery Shield is an essential accessory for enabling portable power solutions for your Wemos D1 Mini or D1 Mini Pro boards. Designed to interface seamlessly with a single-cell 3.7V lithium battery, this shield incorporates an efficient DC-DC boost converter that elevates the battery’s voltage to a stable 5V output, delivering up to 1A of current. This setup ensures that your development board and connected peripherals receive consistent power, making it ideal for mobile and remote applications.
Charging the battery is straightforward: connect the shield to a 5V power source via the micro USB port, and the integrated charging circuit manages the process automatically. Dual LED indicators provide clear visual feedback—red indicates active charging, while green signifies a fully charged battery. Additionally, the shield features a jumper (J1) that allows you to select the charging current, offering options of 0.5A or 1A to accommodate various battery capacities and charging requirements.
