D1 LOLIN32 ESP32 ESP-32 CP2104 Wireless WiFi Bluetooth Development Board Micro USB Dual Core CPU 4 MB Flash Module
WeMos LOLIN32 module is somewhat larger than the well-known WeMos, but that is also possible with the extra functionality and I / O. This module is based on the ESP-32, with 4MB flash, WIFI, and Bluetooth. In addition, this module has a built-in interface, with which a lithium battery can be connected and even charged (max 500mA). To become Lite, the LoLin32 has to lose a few pins. The RX / TX and 5V pins are no longer present on the board. There is only one GND pin (instead of 5) and only one 3V3 pin (instead of 2). All I / O pins are available (x21 in total) which will allow you to exploit all the possibilities offered by the ESP32. The JST connector used to power the LoLin32 Lite using a LiPo battery is always present. It is now oriented in the extension of the board to the left of the micro-USB connector. The micro-USB port is always present. It is used for programming (code Arduino, Lua, or micro-python) as well as for the charge of the battery. The LoLin32 Lite status LED is always present. The Reset button has moved between the two micro-USB and LiPo battery connectors.
