TTGO Mini T7 V1.3 Esp32 Development board
US$17.97
This board is the smaller version of ESP32, i.e mini ESP32. If you're interested in making your project connect to the web and be part of IOT (Internet of Things), then this board is the gadget for you! Like other microcontrollers and microprocessors, the ESP32 now has built in power regulation circuits, on board antennas and noise filters and fits snuggly onto a breadboard for rapid prototyping. The ESP32 can interface with other MCUs as master or slave or function completely standalone through SPI/SDIO, I2C and UART. The microcontroller can also support an SD card and multiple sensors with its 32 GPIO pins (all of which can be used for PWM).
