HELTEC WIFI 32 module is an ultra-performance that is high ultra-low-power consumption Wi-Fi and Bluetooth wireless platform based on ESPRESSIF ESP32 chipset. ESP-32S dual-core 448 KByte ROM | 520 KByte SRAM | 16 KByte SRAM in RTC | 802.11 b/g/n/e/I Wi-Fi | Bluetooth v4.2 BR | EDR & BLE | clocks & Times |peripheral Interfaces and security mechanism.

ESP-32 Wifi Bluetooth combo module provides SDK Firmware for fast programming that is on-line open source toolchains based on GCC for development support. It is designed for Generic power that is low sensor hub, loggers, video steaming for camera, Wi-Fi & Bluetooth enabled devices, Home automation and mesh network applications, aimed at makers, hardware engineers, software engineers and solution provides. ESP32 is a chip that is a single GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low-power 40 nm technology. It is designed and optimized for the powerful performance that is best, RF performance, robustness, versatility, features, and reliability, for a wide variety of applications, and different power profiles.

HELTEC WIFI 8 is driven by ESP8266 SOC chip,  ESP8 module has a preprogrammed firmware which supports the serial interface communication by controlling using AT commands. The ESP8266 chip was developed by ESPRESSIF System, a smart connectivity platform or ESCP that provides high performance, high integration wireless SOCs, the chip designed for space and power-constrained mobile platform. The ESP8266 provides unsurpassed ability to embed Wifi capabilities within another system, or to the application, and minimal space requirement.
