Heltec Automation LoRa ESP32 OLED Display Bluetooth WIFI IoT Development Board for Arduino

The WIFI Kit series from Heltec Automation is a cost-effective networking solution featuring the Lexin ESP32 chip. It comes equipped with a Tensilica LX6 dual-core processor clocked at 240MHz, delivering computing power up to 600DMIPS. The chip includes 520 KB SRAM, an 802.11 b/g/n HT40 Wi-Fi transceiver, baseband, protocol stack, and LWIP. Additionally, it supports dual-mode Bluetooth (classic and BLE). Enhanced with the SX1262 chip, this board supports LoRa communication at 868/915MHz frequency, offering high sensitivity (-139dBm) and a power output of +20 dBm, ensuring reliable long-distance transmission up to 2.8km in open areas.

The board integrates 32MByte Flash, a Wi-Fi antenna, a 0.96-inch blue OLED display, a lithium battery charging circuit and interface, and a CP2102 USB to serial chip. It is fully compatible with the Arduino development environment, allowing for easy and rapid program verification and product development.
