NANO32 ESP32 IoT Development Board

The NANO32 ESP32 IoT Development Board is the product by the designers of Arduino Nano and Espresso Lite (Thailand-based Gravitech and MakerAsia respectively) is the first third-party development board that provides another alternative to the eager-beavers community of geeks, makers, hackers and developers interested in the latest Wi-Fi/BT combo ‘wonder’ chip.

This NANO32 ESP32 IoT Development Board is the big brother of the ESP8266 development board. Nano32 is collaboration work by Makerasia and Gravitech from Thailand. It is base on ESP32 SoC. ESP32 the flagship product from Espressif (the company that design and produce ESP8266), but now with Xsensa Dual-Core 32-bit processors that case provides 600DMPIS. Let’s look at the features and Specification of this board.

The ESP32 is the latest chipset to be released by Shanghai-based, Espressif Systems that combines both Wi-Fi and Bluetooth (BT) capabilities within its dual CPU core and a rich accompaniment of hardware peripherals.
