OVERVIEW

GebraBit ESP8266 is an integrated Wi-Fi SoC Module that meets users’
Continuous demands for efficient power usage, compact design, and reliable performance in the Internet of Things industry.

GebraBit ESP8266, which features a PCB antenna and 26Mhz crystals, operates with a 5V input Supply Voltage due to an integrated 3V3 regulator which its output is accessible on the “3V3” pin. Also, Users can access the most important pins of the ESP8266 through the GebraBit ESP8266 module. Pins like HSPI, UART, I2C, I2S, IR REMOTE CONTROL, PWM , ADC, ENABLE,  RESET, and GPIO.Users can program and upgrade the ESP8266 firmware in (8M-bit) Serial Flash memory through UART and GPIO0 pins.

Although ESP8266 on this module is enabled by default through the ‘R3’ resistor, users can control ESP8266 by the ‘ENA’ pin. 

The GebraBit ESP8266 module can be driven via the serial interface using the standard AT commands.

As its clear, the module core is ESP8266EX , With the complete and self-contained Wi-Fi networking capabilities, ESP8266EX can perform either as a standalone application or as the slave to a host MCU. When ESP8266EX hosts the application, it promptly boots up from the flash. The integrated highspeed cache helps to increase the system performance and optimize the system memory.Also, ESP8266EX can be applied to any microcontroller design as a Wi-Fi adaptor through SPI/SDIO or UART interfaces. ESP8266EX integrates antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. The compact design minimizes the PCB size and requires minimal external circuitries. Besides the Wi-Fi functionalities, ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM. It can be interfaced with external sensors and other devices through the GPIOs. Software Development Kit
(SDK) provides sample codes for various applications.
