HW100, Mini ESP32 WROVER-B WiFi + Bluetooth Development Board with CP2104 USB Chip
This microcontroller has TWO microprocessor 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 you are able to 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!
With pre-soldered breadboard headers and built-in USB-serial adapter, all you need is a microUSB cable to connect it to your computer. No external programmer necessary.
