by the party responsible for compliance could void the

user’s authority to operate the equipment.

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 in­clude: 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.

Communication Interfaces

• Wi-Fi

• BLE

• RMii

• SPI, I2S, I2C

• I/O

• UART (RS232, RS422, RS485)

Wi-Fi, BLE

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.

Processor

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.

Software / Firmware

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 rmware can be updated remotely without manual or

physical intervention. The AWS cloud extensions provide an application interface (API) for develop­ers that want to implement cloud applications.

Grid Connect has made available for the GC-ESP32-PORT family different rmware 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 rmware available

If you wish to develop your own software/rmware 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.
