Information

WiFi Kit 32 is a classic IoT dev-board designed & produced by Heltec Automation(TM), it’s a highly integrated product based on ESP32 (include Wi-Fi and BLE), Li-Po battery management system, 0.96″ OLED are also included. It’s the best choice for smart cities, smart farms, smart home, and IoT makers.

WiFi Kit 32 is a part of the “Heltec ESP Arduino“ series, with the following features:

Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core);
Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching);
Onboard Wi-Fi, Bluetooth 2.4GHz PCB antenna;
Onboard 0.96-inch 128*64 dot matrix OLED display, which can be used to display debugging information, battery power, and other information;
Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
Compatible with the Arduino development environment.
