Waveshare NodeMCU-32S ESP32 WiFi+Bluetooth Development Board
- Overview
- This is the NodeMCU development board based on ESP32, features WiFi+Bluetooth connectivity, onboard CP2102 and keys. What's more, all the I/O pins of ESP-WROOM-32 module are accessible via the extension headers.
- Thanks to the rich open-source resources, it supports development in various ways such as Lua/AT commands/MicroPython/Arduino/IOT source code, etc. helps you to fast prototype IoT applications.
- Onboard ESP-WROOM-32 module
- Onboard CP2102, USB to UART converter
- USB port for power input, firmware programming, or UART debugging
- 2x19pin extension headers, breakout all the I/O pins of the module
- 2x keys, used as reset or user-defined

LDTR-WG0227 TEC1-12706 40x40mm Thermoelectric Cooler Peltier Refrigeration Plate Module, 12V 60W
- Its work is characterized by side refrigeration and side fever
- Hot and cold on both sides of the temperature difference of 68 degrees
- Connected to the 12-volt power supply cooling piece on both sides there will be difference in temperature, side cold side of the heat, do not long power cooler radiator, otherwise it will cause cooler internal overheating and burning
- These devices must be used in conjunction with a heat sink to avoid burned
- Each device is full inspected and tested
- Fitted with 6-inch insulated leads
- Size: 40mm x 40mm
- Operates from 0~15.2V and 0~6A
