Grid Connect Inc. ESP32P001 Manuel D’Utilisation

GC-ESP32-PORT-N 

Description:

Features:

The GC-ESP32-PORT is a family of embedded networking modules that allow the user to create a 

customized modular solution for all of their networking requirements.  The GC-ESP32-PORT 

modules are all based on the powerful ESP32 processor.  The ESP32 processor has all the 

communication interfaces required to implement today’s wired and wireless standards; these in-

clude:  Wi-Fi, BLE, Ethernet, UART (RS232, RS485), I2C, I2S, and SPI.  Each module has different 

communication hardware and software options that are available for use.

• 

Wi-Fi

• 

BLE

• 

RMii

• 

SPI, I2S, I2C

• 

I/O

• 

UART (RS232, RS422, RS485)

Having a combination of BLE, and Wi-Fi on board makes the modules suitable for a 

variety of wireless networks, allowing for both Wi-Fi based internet connections and local BLE 

connections to a smart phone or tablet.

TBD

The ESP32 has two CPU cores that can be individually controlled and a clock frequency that is 

adjustable from 80 MHz to 240 MHz.  The ESP32 also has a sleep mode processor that allows for 

sleep current of less than 5 µA, making it suitable for battery powered applications.

 

The GC-ESP-PORT component utilizes the free RTOS operating system (now owned by Amazon/

AWS) with LwIP and a built-in TLS 1.2 with hardware acceleration. It also offers secure, encrypted 

over-the-air (OTA) updates so that the module firmware can be updated remotely without manual or 

physical intervention.  The AWS cloud extensions provide an application interface (API) for develop-

ers that want to implement cloud applications. 

Grid Connect has made available for the GC-ESP32-PORT family different firmware and hardware 

that allows the user to use for standard applications:

• 

Serial tunneling between the UART and Wi-Fi

• 

Serial tunneling between the UART and Ethernet

• 

Bridging between Wi-Fi and Ethernet

• 

Basic AWS cloud connection

• 

Custom firmware available 

If you wish to develop your own software/firmware there is a standard SDK with many options for 

your application.  The development environment for ESP32 is available on-line and is open source 

and free.
