Description
IOT Development Board
ATMega328-au fully 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 for HopeRF 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
