IOT Development Board

ATMega328-aufully compatible with the Arduino IDE

Support for Optiboot and DualOptiboot Bootloaders

Extremely low power consumption when asleep typically 8uA

External 8Mhz crystal oscillator to allow support for the critical timing required by the LORA radios and the LMIC LoRaWAN

Precision resistor divider to accurately measure the battery voltage before the regulator

Real time clock with temperature compensation to provide a high level of accuaracy for time critical functions such as scheduling of transmissions and timestamping events.

Support forHopeRF HCW69HCW and RFM95 Lora radios

On board EUI-64 unique ID accesible over the I2C bus

On board 4Mbit SPI flash for configuration data storage and code updates using DualOptiboot

Precision voltage regulator with quiescent current of only 1ua allowing supply voltages between 2.8v and 6.0v

U.FL connector for connection of a range of antenna options
