WeMos D1 Lithium Battery Charger Board with Mini USB

Admin — Thu, 29 Feb 2024 16:10:44 +0000

The WeMos lithium battery shield provides a means of powering your WeMos mini, or WeMos mini Pro (see item HCWEMO0002) from a single cell (3.7V) lithium battery. The shield contains a DC-DC converter to step-up the batteries 3.7V to 5V supplying your WeMos mini and shields with up to 1A of power. When the battery is depleted simply plug the shield into a USB power source using a mini USB cable and it will automatically recharge the battery. Two LEDs on the shield indicate when the battery is charging and when charging has been completed.

You can use D1 mini without a USB cable, it’s really wireless now. Put D1 mini anywhere, using this battery shield and a lithium Battery.

Connect to the lithium battery (normal 3.3-4.2V)
Charging port (normal 5V)
Green LED lights up when charging is complete
Red LED, lights when charging

Specification:

Charging Voltage: 10V MAX 5V Recommended
Charging Current: 1A

Ports:

XH2-2.54mm (Port 1): Connect to lithium battery (3.3-4.2V)
Micro USB: Charging Port (5V)
Green LED: Illuminates when charging is complete
Red LED: Illuminates when charging is in progress
J1: Sets the maximum charging current: 0.5A or 1A

WeMos LOLIN32 V1.0.0 based on ESP32 Rev1 Wifi Bluetooth Board

Admin — Thu, 29 Feb 2024 16:09:04 +0000

This is WeMos LOLIN32 V1.0.0 based on ESP32 Rev1 Wifi Bluetooth Board. The board design is basically perfect. It takes more than a little inspiration from Adafruits Feather series.

It has 4 MB flash memory onboard, a USB-serial adapter (cp210x), and a LiPo battery charger and connector. All the relevant pins are broken out and well-labeled, especially on the bottom. It has a nice central reset button, and even a single user LED for your blinking pleasure.

For the price, it has one more feature (the LiPo) than wed ask for. It even (barely) fits into a standard breadboard. Cant beat that with a stick. No wonder they stocked out in the first week.

Note: A 2 mm JSTXH Connecter is compatible with this module.

Features :

WIFI
Bluetooth
4MB Flash
Lithium battery interface, 500mA Max charging current.

Specifications :

Microcontroller : ESP-32
Operating Voltage (VDC) : 3.3
Digital I/O Pins : 26
Analog I/O Pins : 12
Clock Speed : 240 MHz
Flash Memory : 4 MB
