WEMOS ESP32 + OLED DEVELOPMENT BOARD
This is the new ESP32 board integrated with OLED module. If you're interested in making your project connect to the web and be part of the grander scheme 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, onboard 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).
This microcontroller has TWO microprocessors inside the metal RF shield as one will act as the co-processor. You have the capability of turning off the main processor when not in use to save power. This microcontroller is close to the same package size of an Arduino Nano, yet deliver features and capability that put its’ competitors to shame.
This microcontroller runs on the AT command, but why stop there. Thanks to the espressif and the git community we were able to test this product and have it running in the Arduino IDE. Simply select the board from the menu and the port option like any normal Arduino device and play with some example files provided! We used the Wi-Fi test code to scan our area for Wi-Fi channels. Super simple to do, follow the guide in the tutorial section to get it up and running! For the detailed view of coding and uploading, follow the Instructables link provided below.
