Feb 14, 2023 — by Giorgio Mendoza 1,042 views

ThingPulse recently launched a new revision ESPGateway which integrates two ESP32 WROVER-IB modules and support for a LoRa E5 module. The device includes a USB-C port for programming, external 2.4GHz antennas, and access to 36x pins from the ESP32 modules to connect sensors, displays, etc.

As in the first revision launched in 2021, the new ESPGateway features the same two ESP32 WROVER-IB modules that come with an IPEX connector for external antennas.

The rear side of the device includes a USB-C connector, a USB-to-Serial chip and a convenient switch to select one of the ESP32 modules to be programmed.

There are four programmable RGB LEDs available, however each ESP32 module can control two of them to indicate status. Each ESP32 module offers access to 18x GPIOs pins, 1x 3.3V pin and 1x GND pin.

According to ThingPulse, the new revision includes a SeeedStudio Grove standard connector for LoRa-E5 modules to send and receive data over the LoRaWAN protocol.

Additionally, the hardware for this product is now officially supported by the OpenMQTTGateway project. ThingPulse suggests using this product in applications such as an ESPNow to Wi-Fi gateway, a BLE to Wi-Fi Gateway, a PAX Counter, a Wi-Fi range extender, etc.
