The WEMOS LOLIN32 ESP32 LITE V1.0.0 is a good choice for small projects where you don’t need so many I/Os, processing power, or interfaces. ESP32 lite is also a good choice for battery-powered projects, as it has a built-in LiPo battery charger.
The ESP32 Lite V1 is a low-cost, low-power development board base on the ESP32-DOWD6Q 28017 (Rev 1) SoC chip from Espressif. WEMOS LOLIN32 ESP32 LITE V1.0.0 has a dual-core Tensilica LX6 microprocessor clocked at up to 240MHz, 520kB of internal SRAM, integrated 802.11 BGN WiFi transceiver, integrated dual-mode Bluetooth (BLE and Classic), 4MB of flash memory, and a LiPo battery charger. It also has 19 digital I/O pins, 6 analog input pins, and support for capacitive touch sensors.
The Lolin32 lite board includes a CH340G chip that converts USB to serial. The CH340G chip on the LOLIN32 ESP32 lite module allows your computer to communicate with the ESP32 microcontroller over a serial connection. This means that you can use a serial terminal program, such as PuTTY, to send commands to the ESP32 and view the output.
The operating voltage of LOLIN32 ESP32 LITE are 3.3v. The WEMOS LOLIN32 ESP32 also has a 5V pin, but this pin is not for power. It is for connecting to the RX/TX pins of another device.
The LOLIN32 ESP32 LITE works by using the ESP32-DOWD6Q 28017 (Rev 1) SoC chip from Espressif. The chip has a number of different power modes, which can use to conserve power. The chip also has a number of different peripherals, which can use to interact with the outside world.
The wemos lolin32 lite Board is the successor to the ESP8266. The microcontroller also has Bluetooth and Bluetooth LE as well as more IO pins and improved analog inputs.
