Depending on the configuration and following revisions, the features of the board are subject to change. For detailed information on hardware specifications, please visit www.seco.com
SECO Easy Edge is an IoT Sensor to Cloud device positioned as the hardware endpoint in the Clea offering, where the Easy Edge microcontroller is paired with Clea services to enable connected, data-driven field deployments. It is based on an ESP32 dual core Xtensa® 32-bit LX6 microprocessor and provides a compact footprint for machine retrofitting scenarios. 
On the connectivity layer, Easy Edge integrates WiFi (802.11 b/g/n) and Bluetooth 4.2 / BLE, and supports optional cellular modem configurations including a quad band GSM/GPRS modem (SIM868) or a global band LTE Cat-M / NB-IoT modem (SIM7080G), with SIM options and RF connectors for external antennas as applicable. 
For integration and I/O, it exposes an RS-232 / TTL UART (jumper selectable), an expansion connector with digital GPIOs (including ultra low power states), analog inputs, I2C, additional UART and PWM, plus onboard accelerometer and optional trusted secure element, with 9V to 24VDC power input and an optional rechargeable battery configuration listed on the page.
For ordering purposes, Easy Edge is referred to by its base code, "SYS-D47".
